Description
超净台用磁力底座移液器、 注射器架、 收纳盘 技术领域
[0001] 本发明涉及一种超净台用磁力底座移液器、 注射器架、 收纳盘。
背景技术
[0002] 在超净台提供无菌环境的科研实验中移液器、 注射器和滴管吸头、 吸管吸头、 酒精棉球、 培养瓶盖、 打火机、 眼科镊是在实验中通常需要使用的实验器材。 其中， 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吋， 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； 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。 。
[0003] 移液器 （pipettor) 作为在科研实验中定量转移溶液的工具， 使用的频率很高， 有吋装有某一吸头的移液器在吸取同样的实验溶液吋会被反复利用。 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。
[0004] 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 溶液吋会被多次利用， 需要在超净台内临吋放置。 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。
[0005] 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 验小器材吋， 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。
[0006] 但在超净台的台面上分别放置移液器架、 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， 导致本来面积就不大的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。 严重吋可导致科研实验的失败。
