Device for the accurate dispensing of small volumes of liquid samples

摘要

A device for accurately dispensing small volumes of liquids in the form of uniform droplets. The dispensing device communicates with a source of compressed air which, during start-up transience of the dispensing device, directs a jet of compressed air at the trajectory of dispensed droplets, thereby deflecting the droplets out of their normal trajectory and away from the collecting surface or container and allowing accurate dispensing.
