Description

一种多用加样盒A multi-purpose sample box

技术领域 technical field

本实用新型涉及一种生化实验室、分子实验室及医院化验室等常用实验加样用具,尤其是涉及一种主要用于四道、八道和十二道加样器的加样盒。 The utility model relates to a commonly used experimental sampling tool for biochemical laboratories, molecular laboratories and hospital laboratories, in particular to a sample loading box mainly used for four-channel, eight-channel and twelve-channel samplers.

背景技术 Background technique

中国专利公开号为CN202049157U于2011年11月23日公开了一种多用加样槽。将该加样槽内部设计为联体的V形凹槽,凹槽为十二道,间隔为四道及八道加样器枪头之间的间隔。该结构的加样槽只方便大中剂量取液使用,很多生化或者分子试验,试剂用量超微且价格昂贵。当V形凹槽内只有少量液体试剂时,液体试剂在V形凹槽的底部会呈现断流、分布不均匀等现象,用多道加样器吸取液体试剂时,则会导致加样器各枪头吸取的液体试剂量不相同,这会造成试验的误差。甚至部分液体试剂无法被吸取而倒掉,造成不必要的浪费。 Chinese patent publication number is CN202049157U on November 23rd, 2011, discloses a kind of multi-purpose sampling tank. The interior of the sampling tank is designed as a conjoined V-shaped groove, the grooves are twelve, and the interval is the interval between four and eight sample injector tips. The sample tank with this structure is only convenient for taking large and medium doses of liquid. For many biochemical or molecular tests, the amount of reagents is very small and the price is expensive. When there is only a small amount of liquid reagent in the V-shaped groove, the liquid reagent will appear broken flow and uneven distribution at the bottom of the V-shaped groove. The amount of liquid reagent absorbed by the gun tip is not the same, which will cause the error of the experiment. Even part of the liquid reagent cannot be sucked and poured out, causing unnecessary waste.

发明内容 Contents of the invention

本实用新型所要解决的技术问题是提供一种即使微小剂量时,仍能够被加样器所均匀吸取,从而节约试剂和减少试验误差的多用加样盒。 The technical problem to be solved by the utility model is to provide a multi-purpose sample adding box which can be absorbed evenly by the sample injector even in a small dose, thereby saving reagents and reducing test errors.

本实用新型解决上述技术问题所采用的技术方案为:一种多用加样盒,包括框架和第一V型凹槽,第一V型凹槽设置在框架内,其特征在于所述的第一V型凹槽底部设置有多个凹孔,相邻凹孔的孔底之间的距离为多道加样器相邻枪头间距,所述的凹孔的口径为2mm~11mm,所述的凹孔的深度为2mm~7mm。 The technical solution adopted by the utility model to solve the above-mentioned technical problems is: a multi-purpose sample loading box, including a frame and a first V-shaped groove, the first V-shaped groove is arranged in the frame, and it is characterized in that the first The bottom of the V-shaped groove is provided with a plurality of concave holes, and the distance between the bottoms of adjacent concave holes is the distance between adjacent tips of the multi-channel sampler. The diameter of the concave holes is 2 mm to 11 mm. The depth of the concave hole is 2mm-7mm.

第一V型凹槽的底部设置有汇流通道,所述的汇流通道的底部呈弧形面,凹孔设置在汇流通道的底部。 A confluence channel is provided at the bottom of the first V-shaped groove, the bottom of the confluence channel is arc-shaped, and the concave hole is arranged at the bottom of the confluence channel.

还包括一个框架,框架包括四个侧边,第一V形凹槽的开口朝上,框架的反面形成两个第二V形凹槽,第二V形凹槽的开口朝下,第一V形凹槽位于两个第二V形凹槽之间。 It also includes a frame, the frame includes four sides, the opening of the first V-shaped groove faces upwards, and the reverse side of the frame forms two second V-shaped grooves, the opening of the second V-shaped groove faces downwards, and the opening of the first V-shaped groove faces downwards. The V-shaped groove is located between the two second V-shaped grooves.

所述的框架呈梯形台,框架的下边宽度为L1,框架的上边宽度为L2,L1=2L2。 The frame is a trapezoidal platform, the width of the lower side of the frame is L1, the width of the upper side of the frame is L2, and L1=2L2.

所述的第二V形凹槽内设置有隔板,分隔成两个加样槽,一个为八道加样器枪头的加样槽,另一个为四道加样器枪头的加样槽。 The second V-shaped groove is provided with a partition, which is divided into two sample slots, one is the sample slot for the tip of the eight-channel sampler, and the other is the sample slot for the tip of the four-channel sampler. .

所述的相邻凹孔之间的上边缘直接相连。避免过多的液体试剂留在相邻凹孔的平台处。 The upper edges between the adjacent concave holes are directly connected. Avoid leaving excess liquid reagents at the lands of adjacent wells.

所述的相邻凹孔之间的分隔壁上设置有导通孔,所述的导通孔的口径为0.8mm~1.2mm。 Conducting holes are provided on the partition walls between the adjacent recessed holes, and the diameter of the conducting holes is 0.8mm-1.2mm.

导通孔的设置,使凹孔之间的试剂也能流通,进一步保证加样器的枪头取样的均匀性。 The setting of the conduction hole enables the reagents between the concave holes to flow, further ensuring the uniformity of sampling by the pipette tip of the sample injector.

所述的凹孔的口径为9mm,所述的凹孔的深度为3.5mm,导通孔的口径1 mm。根据大量的实验证明,采用上述尺寸时,取样的均匀性最好。  The diameter of the concave hole is 9 mm, the depth of the concave hole is 3.5 mm, and the diameter of the through hole is 1 mm.

When a drop of liquid reagent is in the shape of a ball on the waterproof membrane, when a small amount of liquid reagent is in the V-shaped groove, the liquid is intermittent and will not be connected into one piece. At this time, it is difficult for the nozzles of the sampler to absorb evenly.

与现有技术相比,本实用新型的优点在于V型凹槽只有微剂量液体时,能避免试剂弥散在V型凹槽的底部各处,液体试剂会集中在各凹孔中,如此,取样时加样器的枪头与凹孔相对应,从而节约试剂并且减少试验误差。 Compared with the prior art, the utility model has the advantage that when the V-shaped groove only has a micro-dosage of liquid, it can prevent the reagent from being dispersed everywhere at the bottom of the V-shaped groove, and the liquid reagent will be concentrated in each concave hole. The gun head of the sample injector corresponds to the concave hole, thereby saving reagents and reducing experimental errors.

汇流通道有利液体试剂集中到各凹孔。 The confluence channel facilitates the concentration of liquid reagents into each concave hole.

框架的正面有一个第一V形凹槽,框架的反面形成两个第二V形凹槽,增加了加样盒的用途。 There is a first V-shaped groove on the front side of the frame, and two second V-shaped grooves are formed on the reverse side of the frame, increasing the usage of the sample box.
