Magnetic particle separation device drive system and negative pressure filling

Aspects of the present disclosure include a system for transporting liquid from a chamber into one or more collection containers. The system can be a semi-automatic system or a full-automatic system. The system may be installed in a sample preparation device, such as a cylindrical cartridge. The system includes a plunger chamber that generates a negative pressure to fill the one or more collection containers. The plunger chamber can be activated using a pivotable lock arm and a trigger coupled to the lock arm. The present disclosure also provides methods of transporting liquid from a chamber into one or more collection containers using the system. 本公开的各个方面包括一种将液体从一个腔室运送到一个或多个收集容器中的系统。所述系统可以是半自动系统或全自动系统。所述系统可安装在样本制备装置(如圆柱形盒)中。所述系统包括一个柱塞室，所述柱塞室产生负压，以填充所述一个或多个收集容器。利用一个可枢转锁定臂和一个与锁定臂耦合的触发器，即可启动所述柱塞室。本公开还提供了使用所述系统将液体从一个腔室运送到一个或多个收集容器中的方法。
