Description
超净台用磁力底座移液器架、 收纳盘、 灭菌托盘 技术领域
[0001] 本发明涉及一种超净台用磁力底座移液器架、 收纳盘、 灭菌托盘。
背景技术
[0002] 在超净台提供无菌环境的科研实验中移液器、 滴管吸头、 吸管吸头、 酒精棉球 、 培养瓶盖、 打火机、 眼科镊、 培养板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； 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； 使用培养板为容器， 对细胞实施孵化和 培养等实验操作。
[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] 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。
[0005] 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。
[0006] 但在超净台的台面上分别放置移液器架、 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 。 严重吋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 灯照射消毒吋， 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， 有吋还出现垫高物不稳导致培养板的跌落。
