在一些实施例中,在基于本说明书提供的纯化设备进行纯化的过程中,当磁珠被转移至分离容器131中后,可以依次向分离容器131中加入第一液体、第二液体等液体。第一液体可以用于对磁珠进行冲洗,以将未与磁珠混合或结合的杂质移除,实现杂质分离。因此利用第一液体冲洗磁珠的步骤也可称为洗杂处理。在一些实施例中,第一液体可以包括洗杂液,其包括Na2HPO4、KH2PO4、NaCl和KCl等。洗杂液可以根据纯化目标物的种类不同而不同,例如,当纯化目标物为核酸时,洗杂液可以包括三(羟甲基)氨基甲烷、甘露醇等。第二液体可以用于对磁珠进行冲洗,以将与磁珠结合的纯化目标物从磁珠上脱离。使其混合在第二液体中从分离容器131排出,便于收集提纯后的纯化目标物。因此利用第二液体冲洗磁珠的步骤可称为洗脱处理。在一些实施例中,第二液体可以包括洗脱液。洗脱液可以包括甘氨酸、柠檬酸盐或者醋酸钠等。洗脱液可以根据纯化目标物的种类不同而不同,例如,当纯化目标物为核酸时,洗脱液可以包括纯水或Tris-HCl。在一些情况下,本说明书提供的纯化设备10可以利用其设置在分离容器131中的过滤件132将磁珠与混合有杂质或者混合有纯化目标物的液体进行分离,使得对纯化目标物的收集更加方便。
在一些情况下,本说明书提供的纯化设备10不需要使用特制的磁珠过滤柱,也不需要在分离容器131中预装第二磁珠,而是直接将混合或结合有纯化目标物的磁珠转移至设置有过滤件132的分离容器131中进行纯化。同时无需利用滤膜对粗样品进行过滤,一定程度上减小了耗材成本。在另一些情况下,由于过滤件132的过滤孔的孔径小于磁珠的直径,因此可以将磁珠截留在分离容器131中,不需要使用第二磁珠的磁性来固定磁珠,使纯化操作更加简便,提高了纯化效率。同时该过滤件132还可以避免磁珠混合在第二液体中经由过滤孔132流出,有效提高了纯化效果。此外,由于本说明书提供的纯化设备10不需要利用滤膜对粗样品进行离心和过滤处理,因此可以避免离心和过滤对纯化目标物造成的损失,提高纯化目标物的回收率。
在一些实施例中,混匀容器112可以是任意具有容纳空间的容器。在一些具体实施例中,混匀容器112可以为适宜进行震荡旋转的容器。示例性的,如图2至图6所示,混匀容器112可以为摇瓶。在一些实施例中,为了防止震荡过程中对混匀容器112造成破坏,在混匀容器112和震荡平台111之间可以设置弹性件。示例性的弹性件可以包括弹簧、弹片以及硅胶垫等。在一些实施例中,混匀容器112的容积可以根据所要容纳的培养液的体积而定。示例性的,混匀容器112的容积的取值范围可以包括300ml~300L。
图10至图21分别示出了利用磁性件121将磁珠15从混匀容器112内部转移至分离容器131的上方开口的过程。该过程包括:将磁性件121伸入混匀容器112内部,并使一部分磁性件121没入液面以下(如图10和图13所示的位置),对磁珠15进行吸附。控制磁性件121移动至混匀容器112外部(如图8和图9所示的位置)。控制磁性件121移动至分离容器131的上方开口(如图14和图17所示的位置)。本说明书不限制磁性件121的具体结构、尺寸,只要能够实现上述描述的功能即可。例如,在纯化过程中,需要将磁性件121伸入到不同结构(例如,混匀容器112、分离组件13的漏斗134等)中,因此需要控制磁性件121的外径。在一些实施例中,磁性件121的外径可以小于分离容器131的上方开口的口径。在一些实施例中,磁性件121的外径可以小于混匀容器112的上方开口的口径。在一些实施例中,磁性件121的外径可以小于漏斗134的广口端的口径。
在一些实施例中,磁性件121可以包括磁棒1211。如前述实施例描述,磁棒1211可以沿震荡平台111的高度方向运动。震荡平台111的高度方向也可以是指震荡平台111的厚度方向。在一些实施例中,当混匀容器112固定于震荡平台111上时,震荡平台111的高度方向可以与混匀容器112的开口至底部的方向平行或近似平行。为了方便描述,在本说明书中,震荡平台111的高度方向可以通过图4、图12和图16中的箭头Y来表示。
结合图7至图11所示,在一些实施例中,转移组件12还可以包括沿震荡平台111的高度方向设置的第一轨道123。磁棒1211可以沿第一轨道123滑动。示例性的,如图7所示,磁棒1211的顶部固定设置有与第一轨道123适配的第一滑动件。通过第一滑动件与第一轨道123配接使得磁棒1211能够沿第一轨道123滑动。在一些情况下,通过设置第一轨道123,可以规范磁棒1211的运动路径,提高磁棒1211在运动过程中的稳定性。
在一些实施例中,转移组件12还可以包括磁棒外套1212。磁棒外套1212可以套设在磁棒1211上,且磁棒外套1212能够相对磁棒1211沿套设方向运动。其中,磁棒外套1212可以是指套设在磁棒1211外的壳体结构。示例性的,磁棒外套1212的一端具有开口,另一端封闭。磁棒1211可以从磁棒外套1212的开口端嵌入磁棒外套1212内,并沿套设方向移动。套设方向可以是磁棒1211的长度方向。在一些实施例中,套设方向可以与震荡平台111的高度方向相同。在本实施例中,当磁棒1211与磁棒外套1212配接(即磁棒外套1212套设在磁棒1211外)并伸入混匀容器112的液面以下时,磁棒1211提供的吸附力会使得磁珠15富集在磁棒外套1212的表面。在一些情况下,套设在磁棒1211外的磁棒外套1212可以对磁棒1211进行保护,避免磁棒1211直接与培养液接触对磁棒1211造成腐蚀。在另一些情况下,由于磁棒外套1212能够相对磁棒1211沿套设方向运动,因此可以将磁棒外套1212与磁棒1211分离,便于清洗或更换。还有一些情况下,可以利用磁棒外套1212能够相对磁棒1211移动的特点,实现磁珠15与磁棒外套1212的分离。关于此,在本说明书其他实施例中有更详细的描述,此处不再赘述。
如图7所示,在一些实施例中,转移组件12沿震荡平台111的高度方向设置的第一轨道123和沿套设方向设置的第二轨道124。第一轨道123与磁棒外套1212相对固定。磁棒1211可沿第一轨道123滑动,磁棒外套1212可沿第二轨道124滑动。在一些情况下,通过设置第一轨道123和第二轨道124,可以同时规范磁棒1211和磁棒外套1212的移动路径,提高磁棒1211和磁棒外套1212在运动过程中的稳定性。
如图7所示,在一些实施例中,磁棒外套1212的开口端固定设置有与第二轨道124适配的第二滑动件,通过第二滑动件能够带动磁棒外套1212沿第二轨道124滑动。同时,第二滑动件背离第二轨道124的一面还设置有第一轨道123,使得第一轨道123与磁棒外套1212相对固定。如图7所示,在一些实施例中,磁棒外套1212的开口端固定设置有与第二轨道124适配的第二滑动件,通过第二滑动件能够带动磁棒外套1212沿第二轨道124滑动。同时,第二滑动件背离第二轨道124的一面还设置有第一轨道123,使得第一轨道123与磁棒外套1212相对固定。在一些实施例中,第二轨道124可以独立于第一轨道123设置。如图8和图9所示,第一轨道124和第二轨道123可以并列设置。
如图10、图14和图18所示,在一些实施例中,转移组件12还可以包括沿震荡平台111的上方至分离容器131的上方方向设置的第三轨道125。磁性件121(例如,磁棒1211)可以沿第三轨道125滑动。从震荡平台111的上方至分离容器131的上方方向可以是指,从固定于震荡平台111上的混匀容器112的上方开口至分离容器131的上方开口的方向。为了方便描述,该方向可以通过图4和图6中的箭头X表示。其中,震荡平台111的上方可以是指震荡平台111的正上方或斜上方,例如,图14至图17中磁棒1211和磁棒外套1212所处的位置。分离容器131的上方可以是指分离容器131的正上方或斜上方,例如,图10和图11中磁棒1211和磁棒外套1212所处的位置。在一些情况下,通过设置第三轨道125,可以规范磁棒1211和磁棒外套1212从震荡平台111上方移动至分离容器131上方过程中的运动路径,提高在运动过程中的稳定性。
需要说明的是,前述实施例对于磁棒1211沿着第一轨道123滑动、磁棒外套1212沿着第二轨道124滑动以及磁棒1211和磁棒外套1212沿着第三轨道125滑动的描述仅出于说明目的,并不旨在限制磁棒1211、磁棒外套1212的运动方式。在一些实施例中,磁棒1211、磁棒外套1212可以通过手动控制(即操作人员用手拿着)进行移动。在另一些实施例中,磁棒1211、磁棒外套1212可以通过驱动装置,例如,通过机械手控制磁棒1211、磁棒外套1212进行移动。
结合图14至图17所示,在一些实施例中,纯化设备10的转移组件12还可以包括防滴挡片126。防滴挡片126可伸缩地设置于第二轨道125的底部。在一些实施例中,防滴挡片126可以
被配置为当磁性件121位于防滴挡片126所在平面以上时时处于伸出状态,当磁性件121位于防滴挡片126所在平面以下时处于收缩状态。例如,当磁棒1211和磁棒外套1212分别沿各自的轨道移动到图14和图16所示的位置时,防滴挡片126可以伸出并位于磁棒外套1212的正下方。在磁性件121从混匀容器112外部移动至分离容器131的上方开口的过程中,防滴挡片126可以位于磁性件121的下方,用于接住磁珠15上所含的残余液体,防止残余液体滴落到纯化设备10的其他部件上造成污染。其中,磁性件121的下方可以是指磁性件121的正上方或斜下方。
结合图18至图24所示,在一些实施例中,纯化设备10还可以包括磁珠脱离组件133。磁珠脱离组件133可以用于将富集在磁性件121表面的磁珠15与磁性件121分离,使磁珠15进入分离容器131中,以便对磁珠15进行后续处理。在一些实施例中,磁珠脱离组件133可以包括冲洗组件1330。冲洗组件1330可以用于对吸附有磁珠15的磁性件121(例如,套设有磁棒1211的磁棒外套1212)进行冲洗,将磁珠15与磁性件121分离。在一些实施例中,冲洗组件1330可以包括冲洗喷头1331。冲洗喷头1331可以设置在分离容器131的上方。
在一些实施例中,冲洗喷头1331可以与外部的泵阀组件连通。泵阀组件可以用于使冲洗喷头1331喷出特定的液体(例如,第一液体、第二液体等)。在一些实施例中,冲洗喷头1331可以设置在分离容器131的上方任意位置,只要冲洗喷头1331朝向分离容器131的上方开口设置,以使喷出的液体能够流入到分离容器131内即可。例如,在图18至图24所示的实施例中,冲洗喷头1331可以设置在分离容器131的上端,其喷口倾斜向下朝向分离容器131的中心轴线。在一些应用场景中,冲洗喷头1331喷出特定的液体可以对磁棒外套1212上的磁珠15进行冲洗。使得磁珠15在液体的冲击下从磁棒外套1212上脱离进入到分离容器131内。在另一些应用场景中,冲洗喷头1331喷出的液体会流入到分离容器131中,对堆积在过滤件132上的磁珠15进行洗杂或洗脱。
在一些实施例中,冲洗组件1330可以包括多个冲洗喷头1331,多个冲洗喷头1331可以间隔环绕设置在分离容器131的上方,提高冲洗效率。
在一些实施例中,冲洗组件1330除了可以用于喷出第一液体和第二液体对磁珠15进行洗杂和洗脱之外,还可以用于对系统管路(例如,排液管路17)或磁珠15进行清洗。示例性的,冲洗喷头1331可以喷出PBS缓冲液、纯水或者氢氧化钠溶液到分离容器131中,对磁珠15以及组件内部(例如,分离容器131内壁、排液管路17等)进行清洗。其中,氢氧化钠溶液一方面可以去除管路中的内毒素,避免下一次纯化实验引入过多内毒素,影响下游实验结果。另一方面可以对磁珠15进行清洗再生,磁珠15清洗后可以用于下一次纯化实验,避免磁珠15浪费,同时防止交叉污染。需要说明的是,冲洗组件1330可以不是必须的。特定液体(例如,第一液体、第二液体或者其他类型的液体)的添加可以通过加液管路实现。例如,分离组件13的上方开口设置有加液管路,加液管路可以与泵阀组件连通,根据需要向分离容器131中加入特定的液体。在一些实施例中,加液管路也可以与冲洗组件1330相结合,两者可以分别喷出不同类型的液体。例如,冲洗组件1330喷出第一液体,加液管路用于加入第二液体。
在一些实施例中,冲洗组件1330还可以包括能够绕分离容器131的中心轴线转动的旋转台1332。冲洗喷头1331可以设置于旋转台1332上。在一些实施例中,旋转台1332可以为圆环状构件,圆环状构件可以套设在分离容器131的上方开口部分的外侧壁,并且能够相对分离容器131的外侧壁转动。
在一些应用场景中,由于磁棒外套1212的侧壁上均富集有磁珠15,若仅通过一个冲洗喷头1331进行冲洗,则磁棒外套1212的部分区域的磁珠15可能无法被冲洗,残留在磁棒外套1212上。若增加冲洗喷头1331的数量,冲洗喷头1331的数量过多可能会导致冲洗喷头1331喷出的液体压力不足,使得冲洗效果较弱。在一些情况下,通过在分离容器131上方设置旋转台1332,使旋转台1332带动冲洗喷头1331绕分离容器131的中心轴线转动,可以增大冲洗喷头1331的冲洗面积,提高磁珠15脱离的效率,进而提高纯化效率。需要说明的是,旋转台1332可以不是必须的,可以通过其他方式实现冲洗喷头1331相对磁性件121的转动。示例性的,磁性件121可以被配置为能够沿其中心轴线进行转动。通过磁性件121自身的转动,同样可以提高冲洗喷头1311的冲洗面积,加快磁珠15脱离。
在一些实施例中,冲洗组件1330还可以包括驱动旋转台1332绕分离容器131的中心轴线转动的旋转驱动组件。仅作为示例,结合图25和图26所示,旋转驱动组件包括旋转电机1351、带轮1352和皮带1353,带轮1352和旋转台1332通过皮带1353实现传动连接,旋转电机1351与带轮1352传动连接。当旋转电机1351驱动带轮1352旋转时,带轮1352能够通过皮带1353带动旋转台1332旋转。在另一些实施例中,旋转驱动组件还可以包括齿轮组件、螺杆螺母组件等。
在一些实施例中,除了利用冲洗组件1330对磁珠15进行冲洗使磁珠15从磁性件121(例如,磁棒外套1212)上脱离外,还可以利用磁性件121本身的特性来实现。例如,可以通过减小磁性件121对于磁珠15的吸附力(即磁力作用),使得磁珠15在重力作用下与磁性件121脱离。
在一些实施例中,可以分别控制磁棒1211和磁棒外套1212沿对应的轨道滑动到图18至图21所示的位置。其中,磁棒外套1212沿第二轨道124滑动至该位置时,磁棒外套1212的底部位于分离组件13的漏斗134内。而磁棒1211则沿第一轨道123滑动至最上方,此时磁棒1211与磁棒外套1212的底部之间的距离最远。在本实施例中,由于磁棒1211与磁棒外套1212的底部距离较远,使得磁棒1211对于富集在磁棒外套1212的底部(即伸入到分离组件13的漏斗134中的部分)的磁珠15的吸附力几乎可以忽略。因此磁珠15可以在重力作用下从磁棒外套1212上脱离。在一些替代性实施例中,磁棒1211可以包括电磁棒。电磁棒通电时具有磁性;断电时,电磁棒磁性消失。在本实施例中,可以通过控制电磁棒的通/断电来控制电磁棒的磁性,进而控制磁性件121对磁珠15的吸附力。示例性的,当需要将磁珠15与磁性件121脱离时,可以停止对电磁棒通电。电磁棒断电后失去磁性,使得磁棒1211与磁珠15之间的作用力消失,磁珠15可以在重力作用下与磁棒外套1212分离。
在一些实施例中,可以将前述实施例中的冲洗组件1330与减小磁性件121对于磁珠15的吸附力相关的实施例相结合,加快磁珠15与磁性件121分离,提高纯化效率。示例性的,磁性件121可以包括磁棒1211和磁棒外套1212,磁棒外套1212和磁棒1211可以分别沿对应的轨道滑动至图18至图21所示的位置;在分离容器131的上方设置有冲洗喷头1331。在一些情况下,通过磁棒外套1212和磁棒1211的相对移动,可以降低磁性件121对于磁珠15的吸附力。同时利用冲洗喷头1331对磁珠15进行冲洗,可以进一步加快磁珠分离的速度。
在一些实施例中,分离容器131的两端均设置有开口,包括上方开口和下方开口。分离容器131中的过滤件132用于将从分离容器131的某一开口(例如,上方开口)进入,从另一开口排出的物质进行过滤。在一些实施例中,过滤件132可以为过滤板,过滤板上开设有过滤孔。过滤板的厚度方向与分离容器131的高度方向平行或近似平行。过滤板沿其厚度方向的横截面轮廓与分离容器131的内部腔体沿其高度方向的横截面轮廓匹配。这里所说的匹配可以是指两者形状相同或近似相同,且尺寸相近,以使得所要过滤的物质无法从过滤件132与分离容器131的内壁之间的缝隙通过。在一些实施例中,过滤件132的中心轴线方向可以与分离容器131的中心轴线方向相同或近似相同。在一些实施例中,磁珠15可以从分离容器131的上方开口处进入分离容器131内部。由于过滤件132的过滤孔的孔径小于磁珠15的直径,因此磁珠15将会被过滤件132截留在分离容器131内部。在一些实施例中,过滤孔的孔径大于生物大分子等物质的直径,以使得作为非纯化目标物的生物大分子(即杂质)和作为纯化目标物的生物大分子与磁珠15分离混入到特定液体中后可以经由过滤孔通过分离容器131的下方开口排出。例如,混合非纯化蛋白的洗杂液可以经由过滤孔从分离容器131的下方开口流出,而磁珠15将会继续堆积在过滤件132上被冲洗。
如图4所示,在一些具体实施例中,分离容器131可以为柱状容器,其两端均设有开口,并且两端的开口相互连通。
在一些实施例中,过滤件132可以设置在靠近分离容器131的下方开口处的位置。例如,在图23和图24所示的实施例中,分离容器131的底部为漏斗状,下方开口的管径小于其余部分的管径。过滤件132可以设置在该漏斗状底部的广口端(下方开口对应漏斗状底部的窄口端)。在一些实施例中,过滤件132可以为筛板。在一些实施例中,筛板可以相对分离容器131拆卸。在一些情况下,可以方便对筛板进行清洗或更换。在另一些情况下,可以取出堆积在筛板上的磁珠15。示例性,筛板可以沿分离容器131的高度方向相对分离容器131向上移动,通过分离容器131的上方开口取出。
在一些实施例中,分离容器131的上方还可以设置有漏斗134。漏斗134可以包括广口端和窄口端,漏斗134的窄口端可以与分离容器131的上方开口连通。如图18至图2所示,在一些情况下,漏斗134的广口端可以用于收容磁性件121(例如,磁棒外套1212),窄口端可以用于连通分离容器131,以保证磁珠15脱离磁性件121之后可以顺利掉落到分离容器131内。同时漏斗134可以防止磁性件121或磁珠15上残余的培养液滴落到分离容器131外造成污染。在一些实施例中,漏斗134的窄口端的外径可以小于分离容器131的内径,使得漏斗134的窄口端可以嵌入分离容器131的上方开口,以保证漏斗134中的磁珠15和/或液体能够流入到分离容器131中。在一些实施例中,漏斗134的广口端的内径大于磁性件121的外径,以使得吸附有磁珠15的磁性件121可以顺利地从广口端伸入漏斗134内。
在一些实施例中,漏斗134可以与前述实施例中的冲洗组件1330相结合。示例性的,漏斗134的广口端可以设置冲洗喷头1331。在另一示例中,旋转台1332可以设置在漏斗134的广口端并且可以沿漏斗134的广口端转动。在又一示例中,旋转台1332可以设置在漏斗134的广口端并且可以沿漏斗134的广口端转动,旋转台1332上还设置有冲洗喷头1331。
图25-图32示出了另一种分离组件的结构示意图。结合图25至图31所示,在一些实施例中,分离容器131可以包括重力柱1311,重力柱1311的上方开口可以与漏斗134连通。分离组件13可以包括密封塞1361,重力柱1311的下方开口可以通过密封塞1361密封。与重力柱1311连通的排液管路(例如,图21中的排液管路17)的入口设置有穿刺针管1362,穿刺针管1362能够穿过密封塞1361。在一些情况下,通过设置密封塞1361和穿刺针管1362,利用穿刺针管1362穿过密封塞1361来将排液管路和重力柱1311的下方开口密封连接,可以有效避免重力柱1311与排液管路的连通处漏液的情况出现。
在一些实施例中,密封塞1361可以由塑料、橡胶、硅胶等材料制成,以便于穿刺针管1362能够顺利穿透,并且穿刺针管1362拔出后,能够及时恢复形变,从而将重力柱1311的下方开口进行密封。
在一些实施例中,重力柱1311内可以设置有塞板,塞板可以作为过滤件132对重力柱1311中的磁珠进行截留。
在一些实施例中,分离组件13还可以包括:支撑架1363,重力柱1311可放置于支撑架1363内;适配结构,适配结构可以用于将不同的重力柱1311与支撑架1363进行配接。其中,不同的重力柱1311可以是指不同规格的重力柱1311。重力柱1311的规格可以是指重力柱1311的尺寸参数,例如,重力柱1311的直径、容积等。在一些情况下,通过设置适配结构,可以实现不同的重力柱1311与支撑架1363的配接。因此即使重力柱1311的规格不同,也可以采用对应规格的适配结构将重力柱1311与支撑架1363配接,使得支撑架1363能够兼容不同的重力柱1311。
在一些实施例中,支撑架1363可以为中空柱状结构,重力柱1311可以放入支撑架1363的内部。在一些实施例中,如图29所示,支撑架1363可以设有观察窗13631,以方便操作人员从外部观察重力柱1311的情况。
在一些实施例中,适配结构可以包括卡扣1364,卡扣1364可以设于支撑架1363的上方开口,用于限制重力柱1311晃动。
在一些实施例中,卡扣1364可以为环状结构,例如,卡环。卡环可以设置在支撑架1363的上方开口处,重力柱1311可以经由卡环放入到支撑架1363内,当重力柱1311晃动时,卡环可以对重力柱1311起到限制作用。例如,卡环可以与重力柱1311过盈配合,从而完全限制重力柱1311的晃动。
在一些实施例中,适配结构还可以包括压头1365,压头1365可以设于支撑架1363的下方开口,压头1365设有液体通道13651,压头1365的上方包括第一抵接面13652,液体通道13651的上方开口设于第一抵接面13652,液体通道13651的下方开口通过密封塞1361密封;重力柱1311的下方开口端包括与第一抵接面13652适配的第二抵接面1312,第一抵接面13652与第二抵接面1312抵接时,重力柱1311的下方开口伸入液体通道13651中。在本实施例中,当重力柱1311放入支撑架1363内之后,在自身重力作用下,重力柱1311会与压头1365抵接,从而使第一抵接面13652与第二抵接面1312抵接,进而使得重力柱1311的下方开口能够伸入液体通道13651中,再通过密封塞1361和穿刺针管1362能够实现与排液管路的密封连接。此外,由于第一抵接面13652和第二抵接面1312适配,因此当两者抵接之后,能够形成密封的效果,防止漏液。
在一些实施例中,第一抵接面13652和第二抵接面1312可以包括适配的锥状面。仅作为示例,如图29所示,第二抵接面1312可以为外锥状面,即锥状面向外凸出,重力柱1311的下方开口从外锥状面的底部伸出,第一抵接面13652可以为内锥状面,即锥状面向内凹陷,液体通道13651与内锥状面的底部连通。在一些实施例中,第一抵接面13652可以为外锥状面,第二抵接面1312可以为内锥状面。在另一些实施例中,第一抵接面13652和第二抵接面1312可以为平面、波浪面等形状。
在一些实施例中,适配结构与支撑架1363可以是可拆卸连接。例如,卡扣1364可以卡接在支撑架1363的上沿。又例如,压头1365可以通过磁吸连接、螺钉连接等方式与支撑架1363的下沿可拆卸连接。
在一些实施例中,如图28所示,分离组件13还可以包括支撑架卡槽1366,支撑架卡槽1366可以用于放置支撑架1363。支撑架卡槽1366上方具有开口,支撑架1363可以从支撑架卡槽
1366的上方开口放入支撑架卡槽1366内。
在一些实施例中,如图29所示,漏斗134的窄口端可以设置O型圈1367,O型圈1367与重力柱1311的上方开口适配,漏斗134的窄口端可以通过O型圈1367与重力柱1311密封连接。仅作为示例,如图29所示,O型圈1367可以设置在窄口端的外沿,当漏斗134的窄口端伸入重力柱1311的上方开口后,O型圈1367可以与重力柱1311的上方开口的内壁形成过盈配合,从而确保漏斗134与重力柱1311连接的密封性。
在一些实施例中,如图30所示,重力柱1311可以包括不同规格的第一重力柱1313或第二重力柱1314,卡扣1364可以包括第一卡扣13641或第二卡扣13642,压头1365可以包括第一压头13653或第二压头13654;第一卡扣13641、第一压头13643可以与第一重力柱1313适配,第二卡扣13642、第二压头13654可以与第二重力柱1314适配。
在一些实施例中,第一卡扣13641和第二卡扣13642可以不同。仅作为示例,第一卡扣13641和第二卡扣13642的规格不相同。在一些实施例中,第一压头13653和第二压头13654可以不同。仅作为示例,第一压头13653和第二压头13654的规格不相同。图30示例性的示出了支撑架1363分别与第一重力柱1313和第二重力柱1314连接的示意图。其中,由于图30中的第一重力柱1313的直径、容积大于第二重力柱1314的直径和容积,因此需要采用尺寸更大的第一卡扣13641(相较于第二卡扣13642)对第一重力柱1313进行固定。此外,第一重力柱1313的第二抵接面1312直径大于第二重力柱1314的第二抵接面1312直径,因此需要直径更大的第一抵接面13652(相较于第二压头13654的第一抵接面13652)进行配合,因而第一压头13653的直径(相较于第二压头13654)更大。
在本实施例中,由于重力柱1311具有不同的规格,因此当更换不同规格的重力柱1311时,可以使用与该规格重力柱1311适配的卡扣1364和压头1365将重力柱1311用于支撑架1363进行连接。在一些情况下,通过设置不同规格的重力柱1311,能够有效满足对于不同纯化目标的需求。此外,通过配备与重力柱1311规格适配的卡扣1364与压头1365(即适配结构),能够使支撑架1363兼容不同规格的重力柱1311,降低使用成本。同时,由于支撑架1363可以兼容不同规格的重力柱1311,因此支撑架卡槽1366也可以持续使用,进一步降低耗材成本。
可以理解的是,关于第一重力柱1313和第二重力柱1314的示例仅出于说明目的,并不限制重力柱1311的规格为两种,除第一重力柱1313和第二重力柱1314,还可以包括其他规格的第三重力柱、第四重力柱等。相应的,每种规格的重力柱1311均具备适配的卡扣1364和压头1365(即适配结构),以便于将不同规格的重力柱1311与支撑架1363进行连接。
在一些实施例中,如图29所示,漏斗134的窄口端设置有压紧法兰1368,压紧法兰1368与卡扣1364配接时,可以将重力柱1311压紧于压头1365上。仅作为示例,在将重力柱1311放入支撑架1363之后,可以通过旋转压紧法兰1368的方式将其与卡扣1364配接,从而实现重力柱1311与支撑架13631的锁紧,同时将重力1311柱压紧在压头1365上。在一些情况下,通过压紧法兰1368和卡扣1364的配合,不仅可以实现重力柱1311与支撑架1363的锁紧,还可以将重力柱1311压紧在压头1365上,有效避免重力柱1311与压头1365脱离导致漏液。
在一些实施例中,除了压紧法兰1368和卡扣1364,还可以通过其他的方式来实现上述效果。在一些实施例中,漏斗134的窄口端可以设置有磁吸件,支撑架1363的上方开口可以设置有磁铁,通过磁吸件与磁铁的磁吸作用可以将重力柱1311与支撑架1363锁紧。
在一些实施例中,结合图29和图30所示,漏斗134可以包括第一漏斗1341或第二漏斗1342,O型圈1367可以包括第一O型圈13671或第二O型圈13672,第一漏斗1341、第一O型圈13671可以与第一重力柱1313适配,第二漏斗1342、第二O型圈13672可以与第二重力柱1314适配。
在一些实施例中,旋转台1332可沿重力柱1311的高度方向运动,以便对重力柱1311进行更换、拆卸或安装。仅作为示例,在纯化设备10工作过程中,漏斗134需要与旋转台1332配合来接收磁珠(如图24及其实施例所描述),而当需要更换、拆卸重力柱1311时,漏斗134需要连同重力柱1311一起更换、拆卸,而旋转台1332会对漏斗134进行干涉,不便于取出重力柱1311,因此需要控制旋转台1332抬升。
在一些实施例中,结合图1、图26和图28所示,分离组件13还可以包括沿重力柱1311的高度方向设置的第一升降轨道1371,旋转台1332可沿第一升降轨道1371滑动。仅作为示例,分离组件13可以包括第一升降轨道1371、第一升降电机1372和第一升降丝杠1373,第一升降电机1372与第一升降丝杠1373传动连接,第一升降丝杠1373与旋转台1332连接,第一升降电机1372
可以驱动第一升降丝杠1373沿第一升降轨道1371运动,从而带动旋转台1332运动。在一些情况下,通过设置第一升降轨道1371,可以规范旋转台1332的运动路径,提高旋转台1332在运动过程中的稳定性。
在一些实施例中,支撑架1363可沿重力柱1311的高度方向移动。在本实施例中,通过控制支撑架1363的重力柱1311的高度方向运动,可以控制穿刺针管1362从密封塞1361拔出或穿入密封塞1361,以便对重力柱1311进行更换、拆卸或安装。仅作为示例,结合图1、图26和图27所示,在纯化设备10工作过程中,穿刺针管1362需要穿入密封塞1361,将排液管路与重力柱1311连通。由于穿刺针管1362相对纯化设备10固定,因此当需要拆卸、拆卸重力柱1311时,可以控制支撑架1363沿重力柱1311的高度方向运动,使穿刺针管1362从密封塞1361拔出,使得重力柱1311在后续运动过程中避让穿刺针管1362。
在一些实施例中,分离组件13还可以包括沿重力柱1311的高度方向设置的第二升降轨道,支撑架1363可沿第二升降轨道滑动。仅作为示例,结合图1、图28和图28所示,分离组件13可以包括第二升降电机1381,第二升降轨道可以包括支撑架卡槽1366的沿重力柱1311高度方向设置的导向轴13661,支撑架1363可以包括沿重力柱1311高度方向设置的导向条13632,导向条13632与导向轴13661适配,第二升降电机1381能够驱动导向条13632沿导向轴13661运动,从而带动支撑架1363抬升或下降。在一些情况下,通过设置第二升降轨道,可以规范支撑架13631的运动路径,提高支撑架13631在运动过程中的稳定性。在另一示例中,分离组件13可以包括与第二升降电机1381传动连接的第二升降丝杠,第二升降丝杠可以与导向条13632连接,第二驱动电机可以通过驱动第二升降丝杠带动导向条13632沿导向轴13661运动。
在一些实施例中,支撑架1363可沿垂直于重力柱1311的高度方向。当穿刺针管1362从密封塞1361中拔出之后,可以控制支撑架1363从旋转台1332的下方移动到其他位置,以便于对重力柱1311进行更换或拆卸。其中,垂直于重力柱1311的高度方向可以是指垂直于重力柱1311高度方向的平面内的某一方向。
在一些实施例中,结合图1和图28所示,分离组件13还可以包括沿垂直于重力柱1311的高度方向设置的平移轨道1391,支撑架1363可沿平移轨道1391滑动。仅作为示例,分离组件13可以包括平移轨道1391、平移电机1392和平移丝杠1393,平移丝杠1393可以与平移轨道1391适配,且与支撑架卡槽1366连接,平移电机1392可以驱动平移丝杠1393沿平移轨道1391滑动,从而带动支撑架卡槽1366以及设置在支撑架卡槽1366上的支撑架1363滑动。
结合图33和图36所示,在一些实施例中,收集组件14可以包括加液口141和收集容器145。收集容器145可以用于收集混合有纯化目标物(纯化目标物含量达到第二含量阈值)的第二液体。加液口141可以与分离容器131的下方开口连通,将分离容器131中的液体排入收集容器145中。示例性的,加液口141可以通过泵阀组件的排液管路17与分离容器131的下方开口连通。
在一些实施例中,收集组件14还可以包括废液暂存容器146。废液暂存容器146可以用于收集洗杂过程中混合有杂质的第一液体(如PBS洗杂液),以及洗脱过程中混合有纯化目标物但其含量未达到第二含量阈值的第二液体(如甘氨酸洗脱液)。在一些实施例中,在洗杂处理阶段,加液口141可以位于废液暂存容器146的上方开口处(如图33所示的位置),用于将分离容器131中的洗杂液排入废液暂存容器146中。在一些实施例中,在洗脱开始阶段,在纯化目标物含量未达到第二含量阈值之前,加液口141依旧可以位于废液暂存容器146的上方开口处,用于将洗脱液排入废液暂存容器146中。直到洗脱液中的纯化目标物含量达到第二含量阈值时,加液口141可以移动到收集容器145的上方开口处,用于将洗脱液存储在收集容器145中。
在一些具体实施例中,如图33所示,废液暂存容器146的内径可以大于收集容器145的内径。在一些应用场景中,由于废液暂存容器146不仅需要存储洗杂液,还可能会用于存储一部分洗脱液。示例性的,当洗脱液中的纯化目标物含量未达到第二含量阈值时,洗脱液可能会被排放到废液暂存容器146当中。基于上述原因,废液暂存容器146的容积可以大于收集容器145的容积。在一些实施例中,废液暂存容器146的底部可以设置有排出管路,排出管路可以与外部的容积较大的容器连通。废液暂存容器146中的废液可以经由排出管路排入到该容器中,防止废液暂存容器146内的液体溢出。
在一些实施例中,收集组件14还可以包括额外加液口142。额外加液口142可以用于排出其他类型的液体,示例性的,其他类型的液体可以包括但不限于中和液、纯水、氢氧化钠溶液等。在一些实施例中,中和液可以包括pH值偏高的缓冲液。在一些应用场景中,当纯化目标物的类型为抗体时,中和液可以用于将收集容器145中的洗脱液中的酸性环境中和成pH中性,避免收集容
器145中的抗体长期处于酸性环境受到破坏。需要说明的是,额外加液口142可以不是必须的,中和液可以通过其他的通道排出。例如,加液口141既可以用于排出分离容器131中的液体,也可以排出中和液。
如图33所示,在一些实施例中,收集组件14还可以包括沿废液暂存容器146上方至收集容器145上方方向设置的第四轨道144。加液口141可以沿第四轨道144滑动。在一些实施例中,在一些情况下,通过设置第四轨道144,可以规范加液口141的移动路径,提高加液口141运动时的稳定性,保证加液口141排出的液体进入收集容器145或废液暂存容器146当中。
如图33所示,在一些实施例中,收集组件14还可以包括底座147。在沿底座147的长度方向上设置有多个孔位。多个收集容器145可以放置在对应的孔位中进行固定,以便于对多个收集容器145批量操作。在一些实施例中,第四轨道144方向可以与从底座147其中一个收集容器145的上方开口至另一个收集容器145的上方开口的方向相同或近似相同,以便于加液口141可以沿第四轨道144从其中一个收集容器145的上方开口移动至另一个收集容器145的上方开口。在一些应用场景中,当其中一个收集容器145中的液面达到一定高度(例如,第三液面高度阈值)时,加液口141可以沿第四轨道144移动到相邻的收集容器145的上方开口排出液体。在一些实施例中,废液暂存容器146可以与底座147相邻设置,以减小加液口141从废液暂存容器146移动至收集容器145所需的距离。
在一些实施例中,如图35所示,收集组件14可以包括底座147和收集容器支架148,收集容器支架148可以用于放置收集容器145,收集容器支架148可以安装于底座147。仅作为示例,收集容器支架148可以包括多个放置孔位,每个放置孔位可以放置一个收集容器145,以便进行批量化操作。
在一些实施例中,结合图34和图35所示,收集容器145可以包括不同规格的第一收集容器1451或第二收集容器1452,收集容器支架148可以包括第一收集容器支架1481或第二收集容器支架1482,第一收集容器支架1481可以用于放置第一收集容器1451,第二收集容器支架1482可以用于放置第二收集容器1452,第一收集容器支架1481的尺寸与第二收集容器支架1482的尺寸相同。其中,第一收集容器支架1481的尺寸与第二收集容器支架1482的尺寸相同可以是指第一收集容器支架1481的长度、高度、宽度等尺寸与第二收集容器支架1482相同。由于第一收集容器支架1481与第二收集容器支架1482尺寸相同,因此第一收集容器支架1481和第二收集容器支架1482的长度方向可以是同一方向,通过图34所示的箭头X1来表示。第一收集容器支架1481的高度方向和第二收集容器支架1482的高度方向可以是同一方向,通过图34所示的箭头Y1来表示。
在一些实施例中,底座147上可以安装一个或多个第一收集容器支架1481或者第二收集容器支架1482。在一些实施例中,收集容器支架148上可以放置一个或多个同样规格的收集容器145。
仅作为示例,第一收集容器1451的容积为50ml,第二收集容器1452的容积为125ml,且第一收集容器1451的外径小于第二收集容器1452的外径。第一收集容器支架1481包括多个第一放置孔位,第二收集容器支架1482可以包括多个第二放置孔位,第一放置孔位与第一收集容器1451适配,第二放置孔位与第二收集容器1452适配。在一些情况下,相同尺寸的收集容器支架148可以兼容不同规格的收集容器145,从而能够安装于同一个底座147上,不仅更方便批量化操作,还能够有效节省设备成本。
结合图33和图36所示,在一些实施例中,收集组件14还可以包括与加液口141连接的加液头143。加液头143可以用于固定加液口141,提高加液口141在工作过程中的稳定性。在一些实施例中,加液头143可以包括依次固定连接的第一板体1431、第二板体1432以及第三板体1433。其中,第一板体1431与第四轨道144滑动连接。第二板体1432相对第一板体1431呈一定角度(例如,90度)设置。第三板体1433与第一板体1431平行或近似平行(例如,两个板体之间的夹角小于5度)。加液口141设置在第三板体1433上。在本实施例中,当由第一板体1431、第二板体1432以及第三板体1433组成的加液头143沿第四轨道144滑动时,可以带动设置在第三板体1433上的加液口141滑动。
在一些实施例中,检测组件可以包括第一检测组件161。第一检测组件161可以是指检测容器中液位(即液面位置)是否达到设定液位的仪器或设备。第一检测组件161可以包括液位传感器,用于检测分离容器131中的液面位置是否达到设定的液位。液面位置可以是指分离容器131中的液体最高点的位置。根据本说明书其他实施例的描述,在纯化过程中,需要向分离容器131中加入第一液体对磁珠15进行洗杂,以及在洗杂完成后加入第二液体对磁珠15进行洗脱。在一些实施
例中,为了保证杂质和纯化目标物更快脱离磁珠15并与液体混合,需要让第一液体或第二液体与磁珠15充分接触,同时也要避免分离容器131中的液体过多发生液体溢出的情况发生。因此需要对分离容器131内的液面位置进行检测并根据检测结果进行调整,使其保持在合适的范围内。在一些情况下,通过在适当位置设置液位传感器,可以检测分离容器131中的液面位置是否达到设定的位置,进而可以根据检测结果控制加液量(例如,可以通过控制冲洗喷头1331喷出的液体量来实现)和排液量(例如,可以通过控制加液口141排出的液体量来实现)。需要说明的是,第一检测组件161可以不是必须的。在一些实施例中,分离容器131内的液体体积可以通过冲洗组件1330(如冲洗喷头1331)排出的液体体积和从分离容器131内排出的液体体积来确定。示例性的,分离容器131内的液体体积可以等于冲洗组件1330排出的液体体积与从分离容器131内排出的液体体积的差值。
在一些实施例中,第一检测组件161可以包括第一液位传感器1611。第一液位传感器1611可以设置在分离容器131的第一位置,用于检测液面位置与第一位置之间的关系。在一些实施例中,第一位置可以为分离容器131的内部腔体的顶部(即分离容器131的上方开口处)至底部(例如,过滤件132上表面所在的位置)之间的任意位置。示例性的,第一位置可以为分离容器131的内部腔体的高度的1/3处。当液位传感器检测到液面位置未达到第一位置时,表明分离容器131中的液位高度过低,液体过少。
在一些实施例中,第一检测组件161还可以包括第二液位传感器1612。第二液位传感器1612可以设置在分离容器131的第二位置。第一位置的高度可以高于第二位置的高度。在本实施例中,第一液位传感器1611可以检测液面位置是否达到第一位置,第二液位传感器1612可以检测液面位置是否达到第二位置。示例性的,设置在第一位置(例如,第一位置为分离容器131的内部腔体的高度的4/5处)的第一液位传感器1611可以用于检测最高液面位置(或称为第一液面阈值)。当液面位置达到第一位置时,表明分离容器131内的液体过多。设置在第二位置(例如,第二位置为分离容器131的内部腔体的高度的1/3处)的第二液位传感器1612可以用于检测最低液面位置(或称为第二液面阈值)。当液面位置未达到第二位置时,表明分离容器131内的液体过少。在一些实施例中,第一液位传感器1611和第二液位传感器1612可以是相同的液位传感器,也可以是不同的液位传感器。
在一些实施例中,液位传感器的类型可以包括但不限于法兰压差液位传感器、浮球式液位传感器、磁性液位传感器、投入式液位传感器、电容式液位传感器、电动浮球液位传感器等。在一些具体实施例中,液位传感器可以为电容式液位传感器,以便于在分离容器131外部对分离容器131内的液位进行检测。
如图23和图24所示,在一些实施例中,纯化设备10的检测组件还可以包括第二检测组件162。第二检测组件162可以用于检测加入到分离容器131中的第一液体的体积。
在一些实施例中,在将磁珠与纯化目标物分离之前,需要检测杂质是否与磁珠分离完毕。当确定磁珠上的杂质移除完毕后,可以利用第二液体对磁珠进行冲洗,以保证磁珠上没有残留的杂质混合在第二液体中或者杂质的含量可以忽略不计。
在一些实施例中,第二检测组件162可以包括第一流量传感器,第一流量传感器可以检测加入到分离容器131中的第一液体的体积。在一些具体实施例中,第一流量传感器可以为第一流量阀,第一流量阀可以设置在冲洗组件(如冲洗组件1330)的冲洗喷头1331上,用来检测冲洗喷头1331喷出的第一液体的流量。当喷出的第一液体的体积达到设定的体积阈值(可称为第一体积阈值)时,表明洗杂处理完成。
在一些替代性实施例中,第二检测组件162可以检测经过滤件132的过滤孔通过分离容器131的下方开口排出的第一液体的体积。当第一液体的体积达到第二体积阈值时,可以表明洗杂已经完成。在一些实施例中,第二体积阈值可以等于第一体积阈值。
在一些实施例中,从分离容器131的下方开口排出的第一液体的体积也可以通过第二检测组件进行检测。在一些实施例中,第二检测组件162可以包括第二流量传感器,第二流量传感器可以检测分离容器131的下方开口排出的第一液体的体积。在一些具体实施例中,第二流量传感器可以为第二流量阀,第二流量阀可以设置在与分离容器131的下方开口连通的排液管路17上,用来检测从分离容器131的下方开口排出的第一液体的流量。
在一些实施例中,检测组件还可以包括第三检测组件163。第三检测组件163可以是指检测液体中某种物质含量的仪器或设备。第三检测组件163可以用于检测与分离容器131连通的排液管路17中第一液体的杂质含量和/或第二液体的纯化目标物含量。示例性的,在洗杂处理过程中,加入第一液体将磁珠15上的杂质移除,磁珠15上的杂质会混合在第一液体中经由过滤件132通过
分离容器131的下方开口排出。可以理解的是,随着洗杂的不断进行,磁珠15上的杂质会越来越少,混合在第一液体中的杂质含量会逐渐降低并趋于稳定。在一些实施例中,当洗杂液中的杂质含量达到第一含量阈值(该阈值可以称为基线)并维持检测时间阈值不变(即没有变化或者几乎没有变化)时,表明磁珠15上的杂质已完全与磁珠15分离或者残余的杂质可以忽略不计,即洗杂完成。
在另一示例中,在洗脱处理过程中,加入第二液体将纯化目标物(例如,目标蛋白)与磁珠15分离,纯化目标物会混合在第二液体中。在一些实施例中,当洗脱液(即第二液体)中的纯化目标物含量逐渐上升并达到第二含量阈值时,表明洗脱已经达到纯化要求,可以对第二液体进行收集,因此可以将其收集至收集容器145中。可以理解的是,随着洗脱的不断进行,第二液体中的纯化目标物含量会逐渐上升至最高点然后下降。在一些实施例中,当第二液体中的纯化目标物含量达到第三含量阈值且处于下降趋势时,表明从磁珠15上分离的纯化目标物较少,可以认为磁珠15上残留的纯化目标物较少或完全没有残留。因此可以停止向分离容器131中加入第二液体并结束对第二液体的收集。第三含量阈值可以是指满足收集要求的第二液体中的纯化目标物含量的最低值。关于确定是否停止收集第二液体的更多细节可以参见图39的描述,此处不再赘述。
如图1、2、4、6、10、14、18所示,在一些实施例中,第三检测组件163可以包括与排液管路17连通的含量检测传感器。在一些实施例中,含量检测传感器的类型与所要检测的杂质类型或者纯化目标物类型有关。为了方便描述,本说明书将以非纯化蛋白(即杂质)以及纯化蛋白为例进行说明。在一些实施例中,含量检测传感器可以包括紫外线吸收检测器。紫外吸收检测器可以根据所要检测的物质对紫外光吸收强弱与所要检测的物质浓度成正比的原理对液体中的特定物质的含量进行检测。示例性的,紫外吸收检测器可以检测第一液体在紫外光吸收峰为280nm处的紫外光吸收值(或称为光密度值),进而根据紫外光吸收值确定液体中非纯化蛋白的含量。示例性的,紫外吸收检测器可以检测第二液体在特定紫外光吸收峰(例如,紫外光吸收峰为280nm)处的紫外光吸收值,从而根据紫外光吸收值确定纯化蛋白的含量。
在另一些实施例中,在检测第一液体中的杂质含量或者第二液体中的纯化目标物含量时,第三检测组件163可以不是必须的,可以通过其他检测组件进行检测。例如,废液暂存容器146上设置有特定的含量检测传感器,可以用于对废液暂存容器146中的纯化目标物含量进行检测。再例如,收集容器145上设置有特定的含量检测传感器,用于对收集容器145中的纯化目标物含量进行检测。
如图33和图36所示,在一些实施例中,检测组件还可以包括第四检测组件164。第四检测组件164可以是指检测容器中液位(即液面位置)是否达到设定液位的仪器或设备。第四检测组件164可以用于检测废液暂存容器146和/或收集容器145中的液面位置是否达到设定的位置。在一些实施例中,第四检测组件164可以设置在收集组件14的加液头143上。示例性的,第四检测组件164可以设置在第三板体1433上,并且被配置为当加液口141位于收集容器145的上方开口时,第四检测组件164也位于收集容器145的上方开口。当加液头143沿着第四轨道144移动时,可以带动第四检测组件164移动到废液暂存容器146或收集容器145的上方开口,对其液面位置进行检测。
如图33所示,在一些实施例中,第四检测组件164可以用于检测收集容器145中的液面位置是否达到设定的第三液面阈值。在一些情况下,当其中一个收集容器145中的液体达到第三液面阈值时,加液口141可以停止加液,防止收集容器145中的液体溢出。在一些实施例中,第四检测组件164可以用于检测废液暂存容器146中的液面位置是否达到第四液面阈值。当废液暂存容器146中的液体达到第四液面阈值时,可以将液体通过设置在其底部的排出管路排到外部的容积较大的容器中,避免废液溢出。
在一些实施例中,第四检测组件164可以包括如前述实施例所描述的一种或多种液位传感器。在一些具体实施例中,第四检测组件164可以包括超声波液面传感器。
在一些实施例中,纯化设备10可以包括第五检测组件165,第五检测组件165可以包括第一光电传感器1651,第一光电传感器1651可以用于检测支撑架1363内是否安装有第一重力柱1313或者第二重力柱1314。仅作为示例,结合图31和图32所示,第五检测组件165包括两个第一光电传感器1651、两个弹簧销1652。两个第一光电传感器1651对称设置在保持架卡槽1366下方。保持架卡槽1366与第一光电传感器1651对应的位置设置有两个安装孔1653,两个安装孔1653的中心轴线均与重力柱1311的高度方向平行。两个安装孔1653内分别设置有一个弹簧1654。为方便描述,两个弹簧销1652中的其中一个可以称为第一弹簧销,另一个可以称为第二弹簧销。两个安装孔1653中的一个安装孔1653可以称为第一安装孔,另一个可以称为第二安装孔。两个弹簧1654中的其中一个弹簧1654可以称为第一弹簧,另一个弹簧1654可以称为第二弹簧。第一弹簧销穿过第一
弹簧且第一弹簧的上端与第一弹簧销抵接,第二弹簧销穿过第二弹簧且第二弹簧的上端与第二弹簧销抵接。弹簧销1652通过弹簧1654可实现沿安装孔1653的中心轴线方向运动。
支撑架1363的导向条13632的数量为两个,两个导向条13632的下端分别与两个安装孔1653对应,其中一个导向条13632的下端面设置有凹槽。为了方便描述,两个导向条13632中的一个可以称为第一导向条,另一个可以称为第二导向条。第一导向条的下端设置有凹槽。导向条13632的下端与安装孔1653对应可以是指导向条13632的下端与安装孔1653对齐,使得导向条13632的下端能抵接弹簧销1652。在一些实施例中,当第一重力柱1313与支撑架1363配接并放入支撑架卡槽1366内时,第一导向条的下端可以与第一安装孔对齐,第二导向条的下端可以与第二安装孔对齐。在一些实施例中,当第二重力柱1314与支撑架1363配接并放入支撑架卡槽1366内时,第一导向条的下端可以与第二安装孔对齐,第二导向条的下端可以与第一安装孔对齐。
当支撑架卡槽1366中未安装支撑架1363时,弹簧销1652的上端均伸出安装孔1653。当支撑架1363以及第一重力柱1313放入支撑架卡槽1366时,第一导向条在支撑架1363以及第一重力柱1313的重力作用下可以抵接第一弹簧销的上端并推动第一弹簧销挤压第一弹簧,促使第一弹簧压缩,进而使第一弹簧销的下端与对应的第一光电传感器1651接触。而当支撑架1363以及第二重力柱1314放入支撑架卡槽1366时,第二导向条在支撑架1363以及第二重力柱1314的重力作用下可以抵接第二弹簧销的上端并推动第二弹簧销挤压第二弹簧,促使第二弹簧压缩,进而使第二弹簧销的下端与对应的第一光电传感器1651接触。所以,当第一弹簧销对应的第一光电传感器1651产生光电传感信号时,表明支撑架卡槽1366内放置有支撑架1363,且支撑架1363内安装有第一重力柱1313。当第二弹簧销对应的第一光电传感器1651产生光电传感信号时,表明支撑架卡槽1366内放置有支撑架1363,且支撑架1363内安装有第二重力柱1314。当两个第一光电传感器1651均未产生光电传感信号时,支撑架卡槽1366内未放置支撑架1363和重力柱1311。
在一些实施例中,结合图34和图35所示,纯化设备10还可以包括第六检测组件166,第六检测组件166可以用于检测底座147上是否安装有第一收集容器支架1481或者第二收集容器支架1482。
在一些实施例中,第六检测设备166可以包括第二光电传感器1661,第二光电传感器1661可以用于检测底座147上是否安装有第一收集容器支架1481或者第二收集容器支架1482。
仅作为示例,第六检测组件166可以包括第一光电感应片1662、第二光电感应片1663和两个第二光电传感器1661,第一收集容器支架1481的长度方向的至少一端设置有第一光电感应片1662,第一光电感应片1662设于第一收集容器支架1481的高度方向上的第一高度位置。第二收集容器支架1482的长度方向的至少一端设置有第二光电感应片1663,第二光电感应片1663设于第二收集容器支架1482的高度方向上的第二高度位置。第一高度位置和第二高度位置不同。
底座147的长度方向上的至少一端设置有两个第二光电传感器1661,两个第二光电传感器1661分别位于底座147高度方向上的第三高度位置和第四高度位置。底座147的长度方向可以通过图35中的箭头X2来表示。底座147的高度方向可以通过图35中的箭头Y2来表示。底座147的长度方向与第一收集容器支架1481的长度方向平行。当第一收集容器支架1481安装于底座147上时,第一高度位置与第三高度位置相同,因此位于第一高度位置的第一光电感应片1662能够被位于第三高度位置的第二光电传感器1661检测到,该第二光电传感器1661可以产生传感信号。当第二收集容器支架1482安装于底座147上时,位于第二高度位置的第二光电感应片1663能够被位于第四高度位置的第二光电传感器1661检测到,该第二光电传感器1661可以产生传感信号。基于上述内容,当位于第三高度位置的第二光电传感器1661产生光电传感信号时,表明底座147上安装的是第一收集容器支架1481。当位于第四高度位置的第二光电传感器1661产生光电传感信号时,表明底座147上安装的是第二收集容器支架1482。当两个第二光电传感器1661均未产生光电传感信号时,表明底座147上没有安装收集容器支架148或者收集容器支架148安装不到位。
在一些实施例中,第一收集容器支架1481的长度方向的两端均设置有第一光电感应片1662,第二收集容器支架1482的长度方向的两端均设置有第二光电感应片1663。如此设置之后,第一收集容器支架1481和第二收集容器支架1482两端的光电感应片均可以被第二光电传感器1661检测到,无需按照特定的方向安装第一收集容器支架1481和第二收集容器支架1482,降低安装难度。
在一些实施例中,第六检测设备166可以包括设置在底座147上的重力检测传感器,通过重力检测传感器可以确定底座147上是否安装有第一收集容器支架1481或者第二收集容器支架1482。仅作为示例,第一收集容器支架1481的自身重量与第二收集容器支架1482的自身重量相同,第二收集容器1452的重量大于第一收集容器1451的重量。当第一收集容器支架1481和第二收集
容器支架1482放置相同数量的第一收集容器1451和第二收集容器1452时,由于,所以第二收集容器支架1482的重量相较第一收集容器支架1481更重,通过底座147上的重力传感器的检测结果即可确定。
在一些实施例中,纯化设备10的一个或多个组件可以通过手动操作的方式执行相应功能。示例性的,结合图2所示,可以手动控制震荡平台111对混匀容器112进行震荡。在另一示例中,结合图16所示,可以手动控制磁性件121伸入混匀容器112内吸附磁珠15。在又一示例中,结合图33所示,可以手动控制加液头143和加液口141沿着第四轨道144滑动,从而移动到收集容器145或者废液暂存容器146的上方开口。
在一些实施例中,纯化设备10的一个或多个组件可以由其他组件进行控制以执行相应的功能。如图1所示,在一些实施例中,纯化设备10还可以包括控制组件18,控制组件18可以用于控制前述实施例中的一个或多个组件执行相应的功能。示例性的,控制组件18可以控制混合组件11进行混匀操作,以使混匀容器112中的磁珠15与纯化目标物充分结合。在另一示例中,控制组件18可以控制转移组件12中的磁性件121从混匀容器112内部运动至分离容器131的上方开口。
在一些实施例中,控制组件18可以包括控制单元181和驱动单元182。控制单元181可以用于接收工作指令,工作指令可以由操作人员输入,用于指示控制组件18驱动一个或多个组件执行相应的功能。在一些实施例中,控制单元181可以根据工作指令生成对应的指令,并将指令发送至驱动单元182。在一些实施例中,驱动单元182可以与纯化设备10的一个或多个组件驱动连接。驱动单元182可以接收来自控制单元181的指令,并根据指令驱动对应的组件执行特定功能。以下将结合纯化设备10的一个或多个组件对控制单元181和驱动单元182进行进一步说明。
如图1和图2所示,在一些实施例中,控制单元181可以根据工作指令生成第一指令并发送至驱动单元182。第一指令与混合组件11的震荡平台111对应,可以指示震荡平台111在设定的工作时间内,按照设定转速对混匀容器112进行旋转震荡。在一些实施例中,驱动单元182接收到第一指令后,可以驱动震荡平台111进行工作。例如,驱动单元182可以控制震荡平台111的电机(例如,图13中的震荡驱动电机113)按照第一指令的指示驱动曲轴(例如,图13中的曲轴114)运动,进而带动震荡平台111旋转。
结合图1、图2和图7所示,在一些实施例中,控制单元181可以根据工作指令生成第二指令并发送至驱动单元182。第二指令与转移组件12以及磁珠脱离组件133对应,可以指示转移组件12的磁性件121(例如,磁棒1211和磁棒外套1212)移动到分离容器131的上方开口处,并指示磁珠脱离组件133将磁珠15与磁性件121分离。在一些实施例中,驱动单元182接收到第二指令后,可以控制磁性件121以及磁珠脱离组件133按照第一指令的指示工作。示例性的,磁性件121可以包括磁棒1211和磁棒外套1212,磁棒1211和磁棒外套1212分别通过第一滑动件和第二滑动件与第一轨道123和第二轨道124滑动连接。驱动单元182可以驱动第一滑动件和第二滑动件运动,从而带动磁棒1211和磁棒外套1212沿对应的轨道运动至图18至图21所示的位置,使磁珠15在重力作用下与磁棒外套1212分离。
结合图1、图2、图6和图10所示,在一些实施例中,控制单元181可以根据工作指令生成第三指令并发送至驱动单元182。第三指令与冲洗组件1330对应,可以指示冲洗喷头1331按照一定的速率喷出特定的液体。驱动单元182接收到第三指令后,可以控制冲洗喷头1331按照第三指令的指示进行工作。示例性的,驱动单元182可以驱动与冲洗喷头1331连通的泵阀组件工作,通过冲洗喷头1331喷出第一液体对磁珠15进行冲洗。
在一些实施例中,控制单元181可以根据工作指令生成第四指令并发送至驱动单元182。第四指令与冲洗组件1330对应,可以指示冲洗喷头1331按照一定的速率喷出特定的液体。驱动单元182接收到第四指令后,可以控制冲洗喷头1331按照第四指令的指示进行工作。示例性的,驱动单元182可以驱动与冲洗喷头1331连通的泵阀组件工作,通过冲洗喷头1331喷出第二液体对磁珠15进行冲洗。
结合图1、图4、和图33所示,在一些实施例中,含量检测传感器可以根据与分离容器连通的排液管路中液体中的特定物质的含量生成检测信号。控制组件18还可以用于根据检测信号控制驱动单元182驱动收集组件14收集分离容器131内的液体。
在一些实施例中,含量检测传感器可以根据与分离容器连通的排液管路中第一液体中的杂质含量生成第一含量检测信号和/或第二液体中的纯化目标物含量生成第二含量检测信号。控制单元181可以基于第二含量检测信号生成第五指令并发送至驱动单元182。第五指令与收集组件14对应,可以指示收集组件14收集来自分离容器131内的第二液体。驱动单元182接收到第五指令后,可
以控制收集组件14按照第五指令的指示进行工作。示例性的,结合图33所示,含量检测传感器检测到与分离容器131连通的排液管路17中第二液体中的纯化目标物含量达到第二含量阈值。因此控制单元181可以生成第五指令,第五指令可以指示收集组件14对第二液体进行收集。驱动单元182在接收到该指令后,可以驱动收集组件14的加液头143沿第四轨道144移动至收集容器145的上方开口,并驱动加液口141排出第二液体至收集容器145。
在一些实施例中,纯化设备10还可以包括上位机,上位机可以是指能够发出操控命令(例如,工作指令)的计算机,如电脑、平板等。上位机可以与控制组件18连接/通讯,通过将工作指令发送给控制单元181,指示驱动单元182驱动相应的组件进行工作。在一些实施例中,上位机可以被手动操控,例如,操作人员可以手动操作上位机中的上位机软件发出工作指令。在另一些实施例中,上位机可以通过控制程序或软件对纯化设备10进行控制。在一些实施例中,上位机可以包括显示装置,例如显示屏。显示屏可以用于将一个或多个检测组件的检测结果以特定的形式(例如,数字、图像等)呈现。在一些实施例中,如图3所示,纯化设备10还可以包括交换机19,交换机19可以用于实现上位机可以与控制组件18连接/通讯。
需要说明的是,本说明书所描述的通过控制组件18对纯化设备10的一个或多个组件进行控制的实施例仅出于说明目的,并不旨在限制控制组件18所能控制的组件具体类型。例如,控制组件18还可以接收第四检测组件164发送的收集容器145中液体的液面位置达到第三液面阈值的检测信号。控制单元181可以基于该检测信号生成第六指令,该指令可以指示加液口141从当前收集容器145的上方移动至另一个收集容器145的上方。驱动单元182接收到该指令后,可以驱动加液头143沿第四轨道144进行移动,从而带动加液口141移动到相应的位置。
在一些实施例中,为了提高纯化效率,可以将多个前述实施例中所描述的纯化设备10进行并联,组成新的第一纯化设备组100。例如,在图37所示的实施例中,第一纯化设备组100由4台纯化设备10并联组成。该第一纯化设备组100的多个纯化设备10之间相互独立,在纯化过程中互不影响。在一些实施例中,第一纯化设备组100的一个或多个纯化设备10可以由同一上位机进行控制。在另一些实施例中,第一纯化设备组100的一个或多个纯化设备10可以由不同的上位机进行控制。需要说明的是,本实施例图37中所示的第一纯化设备组100包括4台纯化设备10,并非表示本发明仅仅局限于扩展到4台,可以扩展的台数不作限定。在一些实施例中,第一纯化设备组100的每个纯化设备10可以完全相同。
在一些实施例中,除了将多台纯化设备10并联来提高纯化效率之外,在一些实施例中,还可以提高单台纯化设备10的组件数量来实现。如图38所示,在一些实施例中,第二纯化设备组200可以包括与本说明书其他实施例中的纯化设备10相同的组件。例如,第二纯化设备组200的震荡平台111、混匀容器112、分离组件13(例如,分离容器131)、收集组件14、控制组件18、检测组件(例如,第三检测组件163)、磁珠脱离组件133、转移组件12(例如,磁性件121)可以与纯化设备10的震荡平台111、混匀容器112、分离组件13(例如,分离容器131)、收集组件14、控制组件18、检测组件(例如,第三检测组件163)、磁珠脱离组件133、转移组件12(例如,磁性件121)相同或相似。不同之处在于第二纯化设备组200的震荡平台111可以固定两个混匀容器112,以及设置有两个分离组件13、两个收集组件14、两个转移组件12以及两个检测组件。第二纯化设备组200的组件均可以通过控制组件18独立进行控制,在工作时互不影响。在一些情况下,通过提高组件数量,提高了第二纯化设备组200纯化效率,还可以使第二纯化设备组200结构更加紧凑,体积更加小巧。本实施例图38中所示扩展到2通道(即组件数量为2),并非表明本发明仅仅局限于扩展到2通道,可以扩展的通道数不作限定。
图39是根据本说明书一些实施例所示的纯化方法的示例性流程图。如图39所示,本说明书还提供一种基于前述一个或多个实施例所描述的纯化设备10,对培养液中的生物大分子进行纯化的方法,该方法3900可以包括以下步骤:
步骤3910、控制混合组件11进行混匀操作。
在一些实施例中,控制混合组件11进行混匀操作包括:首先将一定量的培养液和一定量的磁珠15放入混匀容器112中,然后将混匀容器112固定于震荡平台111并控制震荡平台111对混匀容器112进行震荡,使磁珠15与培养液中的纯化目标物结合。
步骤3920、控制转移组件12中的磁性件121将磁珠15转移至分离容器131的上方开口。
在一些实施例中,控制转移组件12中的磁性件121将磁珠15转移至分离容器131的上方开口包括:将磁性件121的一部分伸入到混匀容器112的液面以下,利用磁性件121的吸附力使磁珠15富集在磁性件121的表面。然后将磁性件121从混匀容器112中取出并移动至分离容器131
的上方开口处。
步骤3930、控制磁珠脱离组件133将磁珠15从磁性件121上脱离,使磁珠15进入分离容器131并堆积于过滤件132上。
步骤3940、控制冲洗组件1330向分离容器131内加入第一液体。通过第一液体冲洗磁珠15来移除未与磁珠15结合的杂质。
步骤3950、控制冲洗组件1330向分离容器131内加入第二液体。通过第二液体冲洗磁珠15使得与磁珠15结合的纯化目标物与磁珠15分离。
步骤3960、控制收集组件14收集来自分离容器131的第一液体和/或第二液体。在一些实施例中,可以通过与分离容器131的下方开口连通的收集组件14收集混合有纯化目标物的第二液体。在一些实施例中,可以控制收集组件14收集来自分离容器131的第一液体。在一些实施例中,可以通过与分离容器131的下方开口连通的收集组件14收集混合有杂质的第一液体。
在一些实施例中,磁性件121可以包括磁棒1211。在将磁棒1211转移至分离容器131的上方开口处的过程中,可以控制磁棒1211沿第一轨道123和第二轨道124滑动,以规范磁棒1211的运动路径,提高运动过程中的稳定性。
在一些实施例中,当磁性件121位于分离容器131的上方开口处时,可以通过设置在分离容器131的上方开口处的磁珠脱离组件133的冲洗组件1330对磁珠15进行冲洗来将磁珠15与磁性件121分离。在一些实施例中,还可以通过减小磁性件121的磁力降低磁性件121对磁珠15的吸附力,使磁珠15在重力作用下与磁性件121分离。例如,可以控制磁棒1211和磁棒外套1212分别移动至图18至图21所示的位置,减小磁棒1211对磁棒外套1212底部的磁珠15的吸附力,使磁珠15在重力作用下脱离。关于通过减小磁性件121的磁力降低磁性件121对磁珠15的吸附力的更多细节,可以参见本说明书其他实施例的描述,此处不再赘述。
在一些实施例中,在洗杂过程中,可以通过第三检测组件163检测与分离容器131连通的排液管路17中的第一液体中的杂质含量。当第一液体中的杂质含量达到第一含量阈值且维持检测时间阈值不变(即没有发生变化或者几乎没有变化)时,表明洗杂完成,可以停止加入第一液体。
在一些实施例中,在洗脱过程中,可以通过第三检测组件163检测与分离容器131连通的排液管路17中第二液体中的纯化目标物含量。当第二液体中的纯化目标物含量达到第二含量阈值时,表明第二液体中的纯化目标物含量满足收集要求,可以对第二液体进行收集。当纯化目标物含量达到第三含量阈值时,表明从磁珠上分离的纯化目标物较少,可以认为磁珠15上残留的纯化目标物较少或完全没有残留,因此可以停止向分离容器131中加入第二液体并结束对第二液体的收集。在一些实施例中,第三含量阈值可以超过第二含量阈值。当第三含量阈值超过第二含量阈值时,若纯化目标物含量达到第三含量阈值,且第二液体中的纯化目标物含量处于下降趋势(例如,可以基于若干个连续的时刻对应的纯化目标物含量数值(如10个数值),确定目前的纯化目标物含量变化趋势),则表明磁珠15上残留的纯化目标物较少或完全没有残留,因此可以停止向分离容器131中加入第二液体并结束对第二液体的收集。若纯化目标物含量不处于下降趋势,则可以继续收集第二液体。在一些实施例中,第三含量阈值可以小于第二含量阈值。当第三含量阈值小于第二含量阈值时,若纯化目标物含量达到第三含量阈值,则可以直接确定停止向分离容器131中加入第二液体并结束对第二液体的收集。在一些实施例中,当停止向分离容器131中加入第二液体并结束对第二液体的收集时,可以视为纯化过程结束。
在一些实施例中,当停止向分离容器131中加入第二液体并结束对第二液体的收集后,还可以对纯化设备10的一个或多个组件、管路以及磁珠15进行清洗、消毒。在一些具体实施例中,可以控制冲洗组件1330(例如,冲洗喷头1331)向分离容器131中加入其他液体(包括但不限于PBS洗杂液、纯水、氢氧化钠溶液)。例如,加入PBS洗杂液、纯水或氢氧化钠溶液等对分离容器131内部、过滤件132、排液管路17以及磁珠15进行清洗、消毒。又例如,将磁棒外套1212和漏斗134等部件浸泡在氢氧化钠溶液中进行消毒。
在一些实施例中,前述一个或多个实施例所描述的纯化方法可以通过控制组件18来实现。在一些实施例中,控制关于控制组件18如何控制一个或多个组件的相关细节可以参见图37相关的实施例,此处不再赘述。
