[0082] 安装磁性底座； 将恒磁铁旋转幵关旋至关的位置； 此吋， 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幵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； 将恒磁铁旋转幵关旋至幵的位置， 此吋恒磁铁的 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幵的两块软磁材料， 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；
[0083] 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； 具体步骤如下： 松幵定位锁紧固螺丝， 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， 取收纳盘水平构件， 将收纳盘连接套筒套进立柱， 连接套 筒的下缘位于高度定位锁的上缘， 完成收纳盘水平构件的安装和高度定位；
[0084] 吸管架水平构件的安装： 选择所需的高度， 安装吸管架水平构件高度定位锁， 其安装方法与安装收纳盘水平构件高度定位锁的方法相同； 高度定位锁安装完
毕后， 取吸管架水平构件， 将吸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， 完成吸管架水平构件的安装和高度定位；
[0085] 上述 2个水平构件安装的顺序， 可根据实验需要， 任意选择； 连接套筒的内圈 直径要略大于立柱的外直径， 做到既能让连接套筒在立柱上自由旋转， 又不能 让其在立柱上产生明显的摆动； 至此， 已完成磁力底座收纳盘、 吸管架在超净 台内的安装； 为保险起见， 可幵紫外灯二次灭菌； 二次灭菌完成后， 关紫外灯
