- 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. Since the syringe barrel is marked with a scale, 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 using a syringe.
- a straw can be reused if it absorbs the same solution. If the straw is placed horizontally, the space occupied by the clean bench is too large.

Description
本发明涉及一种超净台用磁力底座收纳盘、吸管、移液器、注射器架。
在超净台提供无菌环境的科研实验中，滴管吸头、吸管吸头、酒精棉球、培养瓶盖、打火机、眼科镊、吸管、移液器和注射器是常用的实验工具。其中，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小器材；使用吸管在试管、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转移实验溶液；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。
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。
吸管作为在科研实验中经常使用的工具，一根吸管如在吸取同样的溶液时会被反复利用。如吸管水平放置，占用的超净台的台面空间太大。而且玻璃吸管在水平放置的情况下，易造成吸管的污染。这就要求人们在超净台内为吸管准备垂直放置的有关装置。人们通常用超净台的台面上放置插入无菌试管的试管架，并将吸管垂直插入该试管中的方法来实现超净台内吸管的垂直放置。
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。
但在超净台的台面上放置试管架、移液器架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和注射器在超净台的台面上，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。
