CLOSED FLUID RECEIVING AND SAMPLING CONTAINER
20210387176 · 2021-12-16 ·

A closed fluid receiving and sampling container that enables transfer of valuable reaction liquid to a receptacle without risking loss of sterility. The sampling container has a dip tube subassembly with a shorter inlet tube bent towards the wall of the receptacle to prevent or reduce foaming, and a longer outlet tube used to drain the waste liquid once the magnetic beads are trapped by the magnet. The dip tube subassembly is injection molded in one piece and provides a sealed cap also with a vent tube therethrough to enable filling and draining the receptacle without removing the cap, thus keeping the process aseptic. The sampling container is especially useful in the context of magnetic bead separation processes.

Automated diagnostic analyzer and method for its operation

An automated analyzer that receives samples prepared for analysis in an automated pre-analytical module and a method of operation of such automated analyzer. The automated analyzer includes a shuttle transfer station that receives a shuttle carrier from the automated pre-analytical system. The shuttle transfer station has a clamping assembly for the shuttle. The clamping assembly has jaws that advance engagement members into contact with a bottom portion of sample containers disposed in the shuttle. The clamping assembly secures the sample containers in the shuttle when sample is aspirated from the sample containers. The automated analyzer also has a multichannel puncture tool that is adapted to be carried by a robotic gripper mechanism. The multichannel puncture tool has multiple puncture members that each defines a channel. Each channel is in communication with a different trough in the consumable. A pipette can pass through the channel in the puncture tool.
