DEVICE, SYSTEM, AND METHOD FOR SELECTING A TARGET ANALYTE OR FLUID

摘要

This disclosure is directed to a device and a system for aspirating and dispensing a target analyte, target material, or fluid. A picker may aspirate and dispense the desired material by introducing a pressure gradient. The picker may include a hydraulic fluid to hydraulically couple at least two components, such as a moveable pump component and a cannula.

主权项

1. A picking system comprising:
a pump block including a first end and a second end including a seal; a piston to be at least partially housed within the pump block and to partially extend through the seal, the pump block to allow translation of the piston relative to the pump block; a cannula including an adapter and a tube end including a picker tip, the adapter to connect to the second end of the pump block and the picker tip to extend away from the pump block; and a hydraulic fluid to at least partially fill a pump volume between the picker tip and the seal to hydraulically couple the piston and the cannula, wherein one end of the piston is to extend into the cannula.
