Definitions
- the invention relates to a test tube for a clean bench, a storage tray, a pipette, a syringe holder and a sterilization tray.
- Test tubes are commonly used experimental tools in scientific research that provides a sterile environment in a clean bench. .
- the test tube is used as an experimental container to complete the operations of dispensing, extracting, washing, incubating, and replacing the sample; the pipette tip, the pipette tip, the alcohol cotton ball, the culture bottle cap, the lighter, and the ophthalmology are experiments.
- Auxiliary laboratory equipment that needs to be used multiple times; use a pipette (rotary aspiration adjustment dial, preset aspiration volume, and attach the tip) in test tubes, reagent bottles, culture flasks, beakers, measuring cylinders, measuring cups, measuring flasks
- the experimental solution was quantitatively transferred between experimental vessels such as a flask.
- the experimental solution of different functions can be transferred by simply changing the tip; by using the syringe and the microfilter, a small amount of the solution can be filtered and sterilized.
- the quantitative transfer of the test solution between the test tube, the reagent bottle, the culture flask, the beaker, the measuring cylinder, the measuring cup, the measuring flask and the Erlenmeyer flask can also be achieved by using the syringe; using the culture plate as a container, the cells are used. Carry out experimental operations such as incubation and cultivation.
- test tube As a test tube, the volume usually has various specifications. In scientific research experiments, these test tubes containing experimental samples often need to be placed vertically in a clean bench to prevent contamination of the experimental sample and spillage of the experimental system. For vertical placement of test tubes of different specifications in a clean bench, it is common to place test tubes on the surface of the clean bench to place the test tubes vertically.
- Pipettes are used as tools for quantitative transfer of solutions in scientific research experiments. The frequency of use is very high. Sometimes pipettes with a tip are used repeatedly when drawing the same test solution. Since the liquid level of the clean bench occupied by the pipette is too large, and the liquid pipette has been sucked, the liquid remaining in the suction head may flow to the pipette and the tip connection portion. Causes contamination of the pipette. This requires people to prepare a vertically placed pipette holder for the pipette in the clean bench. To ensure the stability of the pipette holder after placing the pipette, the pipette holder generally has a larger base area.
- Syringes are commonly used as tools in scientific research experiments. In the experiment, a syringe was used multiple times in the clean bench because it was used multiple times when transferring the same experimental solution. The horizontal placement of the syringe on the level of the clean bench will occupy the space of the clean bench, and may also be contaminated by contact of the injector head with other laboratory instruments.

Since the culture plate cannot be autoclaved, the general laboratory does not have the conditions for radiation sterilization. Therefore, it is common to sterilize the culture plate by ultraviolet light irradiation in a clean bench under aseptic conditions. In order to ensure the effect of UV light irradiation, the distance between the UV lamp and the culture plate should be controlled within 30 cm. Therefore, it is necessary to find some objects in the clean bench to raise the culture plate to be close to the light source of the ultraviolet lamp.

Description
本发明涉及一种超净台用试管、收纳盘、移液器、注射器架、灭菌托盘。
在超净台提供无菌环境的科研实验中，试管、滴管吸头、吸管吸头、酒精棉球、培养瓶盖、打火机、眼科镊、移液器、注射器和培养板是常用的实验工具。其中，使用试管为实验容器，完成对实验样品的分装、提取、洗涤、孵育和容器更换等操作；滴管吸头、吸管吸头、酒精棉球、培养瓶盖、打火机、眼科镊是实验中需要多次使用的辅助实验器材；使用移液器（旋转吸液调节转盘，预设吸液量，并装上吸头）在试管、试剂瓶、培养瓶、烧杯、量筒、量杯、量瓶和三角烧瓶等实验容器间定量转移实验溶液。在吸取不同体积的实验溶液时，只要更换吸头，就能转移不同功能的实验溶液；通过注射器和微型滤器配合使用，能实现少量溶液的过滤除菌。由于注射器针筒上标有刻度，使用注射器也能实现实验溶液在试管、试剂瓶、培养瓶、烧杯、量筒、量杯、量瓶和三角烧瓶之间的定量转移；使用培养板为容器，对细胞实施孵化和培养等实验操作。
作为实验容器的试管，容积通常有多种规格。在科研实验中，这些装有实验样品的试管经常需要垂直放置在超净台内以防止实验样品的污染和实验体系的溢出。为不同规格试管在超净台内的垂直放置，人们通常在超净台的台面上放置相应规格的试管架来垂直放置这些试管。
在需要使用滴管吸头、吸管吸头、酒精棉球、培养瓶盖、打火机、眼科镊等实验小器材时，人们通常将这些实验小器材，放在相关的容器中，或将这些实验小器材散放在超净台的台面上。
移液器作为在科研实验中定量转移溶液的工具，使用的频率很高，有时装有某一吸头的移液器在吸取同样的实验溶液时会被反复利用。由于移液器水平放置占用的超净台的台面空间太大，而且已吸过液体的移液器，上次吸液残留在吸头中的液体可能会流向移液器与吸头连接部分，造成对移液器的污染。这就要求人们在超净台内为移液器准备垂直放置的移液器架。为保证放入移液器后移液器架的稳定性，移液器架一般有较大的底座面积。
注射器作为科研实验中常用的工具。实验中，一支注射器由于在转移同一实验溶液时会被多次利用，需要在超净台内临时放置。注射器在超净台台面的水平放置会占用的超净台的台面空间，还有可能因注射器头部与其他实验器具的接触而污染。
在细胞培养实验中，必须对培养板，尤其是二次使用的培养板进行无菌处理。由于培养板不能进行高压灭菌处理，一般的实验室又没有辐射灭菌的条件。所以，人们通常在无菌条件的超净台内，对培养板用紫外灯照射的方法进行灭菌处理。为了保证紫外灯照射的效果，紫外灯与培养板之间的距离要控制在30厘米以内。因此，需要在超净台寻找一些物体垫高培养板，使其靠近紫外灯的光源。
但在超净台的台面上放置试管架、移液器架、注射器和收纳上述实验小器材的容器，或直接将上述的实验小器材散放在超净台的台面上，会较大的占用超净台的台面空间，导致在超净台台面上出现的实验样本、实验试剂和实验器材的拥挤现象，这些现象会妨碍科研实验快速和高效的实施过程，影响科研实验的精度和准确率。严重时可导致科研实验的失败。在超净台寻找一些物体垫高培养板进行紫外灯照射消毒时，由于超净台对放置的物品有一定的要求，寻找这些垫高物会比较麻烦，有时还出现垫高物不稳导致培养板的跌落。
本发明的目的在于提供一种结构合理，使用方便，放置空间可调的超净台用试管、收纳盘、移液器、注射器架、灭菌托盘。

使用方法：
预处理：用消毒液对超净台用试管、收纳盘、移液器、注射器架、灭菌托盘各构件部分进行擦拭灭菌，以确保安装在超净台内的具有磁性底座的试管、收纳盘、移液器、注射器架、灭菌托盘不会改变超净台内的无菌环境；如频繁使用，则将其长期放置在超净台中，免除用消毒液的擦拭灭菌；
磁性底座的安装：将恒磁铁旋转开关旋至关的位置；此时，恒磁铁的N和S极处于水平位置，磁力线在被非导磁材料隔开的两块软磁材料中形成闭路，磁性座吸附面没有磁性，可自由移动；将磁性底座放置所需位置，具体操作为：将磁性座吸附面与超净台内铁质的垂直边板接触，磁性座底面与超净台内的底面接触；旋转恒磁铁旋转开关至开的位置，此时恒磁铁的N和S极处于上下位置，恒磁铁的N和S极分别对准被非导磁材料隔开的两块软磁材料，从N极到软磁材料到超净台内的铁质垂直边板到另一块软磁材料到S极，形成磁力线闭合，可将磁性座吸附面牢牢的吸附在超净台内的铁质垂直边板上；
试管架水平构件的安装：选择所需的高度，安装试管架水平构件高度定位锁；具体步骤如下：松开定位锁紧固螺丝，将定位锁中间的柱形孔套入立柱，选择所需的高度，拧紧定位锁紧固螺丝，使定位锁的硅胶垫与立柱紧紧抱合；高度定位锁安装完毕后，取试管架水平构件，将试管架连接套筒套进立柱，连接套筒的下缘位于高度定位锁的上缘，完成试管架水平构件的安装和高度定位；
收纳盘水平构件的安装：选择所需的高度，安装收纳盘水平构件高度定位锁，其安装方法与安装试管架水平构件高度定位锁的方法相同；高度定位锁安装完毕后，取收纳盘水平构件，将该构件的连接套筒套进立柱，连接套筒的下缘位于高度定位锁的上缘，完成高度定位；完成收纳盘水平构件的安装和高度定位；

带盖塑料微型试管（以下简称试管）的放置：根据实验需要，旋转调整试管架板的水平位置；根据试管的规格，选择向不同规格的试管下挂孔垂直放置或取出试管，由于试管的管口端的直径要大于试管管体的直径，所以直径小的管体可垂直插入试管下挂孔中，而直径大的管口端却卡在试管下挂孔的上方，保证了试管的垂直放置；
收纳物的放置：根据实验需要，水平旋转调整收纳盘的水平空间位置，收纳物放置板边框围绕圆形收纳物放置板，并高于收纳物放置板的板面1cm，用于防止收纳物的脱落；根据实验需要在收纳物放置板上放入或取出包括滴管吸头、吸管吸头、酒精棉球、培养瓶盖、打火机、眼科镊的实验常用小器材；
移液器的放置：根据实验需要，旋转调整移液器架板的水平位置；向移液器下挂槽垂直放置或取出移液器，由于移液器根部呈向两侧伸展，所以其宽度要大于移液器的其他部分的直径；所以宽度小的移液器部分能插入移液器下挂槽中，而宽度大的移液器根部却卡在移液器下挂槽的上方，实现了移液器在移液器架上的垂直放置；
注射器的放置：根据实验需要，旋转调节注射器架板的水平位置；向注射器水平放置槽水平放置或取出注射器；
塑料材质的细胞培养板（以下简称培养板）的放置：根据实验需要，水平旋转培养板水平放置板的位置，将培养板和培养板盖放入由防滑脱边框包绕的空间中，培养孔和培养板盖的内面要面向紫外灯；打开超净台内的紫外灯对他们实施灭菌处理；灭菌处理结束后，关掉紫外灯，在无菌条件下，盖好培养板盖，从灭菌托盘上取下已灭菌的培养板，备用；
拆卸：需要从超净台内取出该具有磁性底座的试管、收纳盘、移液器、注射器架、灭菌托盘时，按从上向下的顺序，先垂直向上从立柱移出并取下灭菌托盘水平构件，松开定位锁紧固螺丝，垂直向上移动，从立柱上取出灭菌托盘高度定位锁；取出注射器、移液器、收纳盘和试管架水平构件的方法与取出灭菌托盘水平构件的方法相同，取出注射器、移液器、收纳盘和试管架高度定位锁的方法与取出灭菌托盘高度定位锁的方法相同；最后将恒磁铁旋转开关旋至关的位置，取出磁性底座即可。
本发明可在几乎不占用超净台台面空间（尤其是不占用超净台中央的台面空间）的前提下，使用一个支架解决了超净台中试管、上述实验小器材、移液器和注射器在超净台内的有序放置问题，及高效的培养板紫外灯照射灭菌问题。并可通过调节立柱上水平构件高度定位锁的位置来分别改变试管架板、收纳物放置板、移液器架板、注射器架板和培养板水平放置板的垂直空间位置。还可通过调节试管架水平构件、收纳盘架水平构件、移液器架水平构件、注射器水平构件和灭菌托盘水平构件的角度来改变试管架板、收纳物放置板、移液器架板、注射器架板和培养板水平放置板的水平空间位置。有利于在超净台中的科研实验操作快速、高效和准确的进行。
