Abstract

There is also provided an apparatus for use on an automated pipette machine for transmitting pressure changes produced by a pump on the machine to a pipette nozzle. The apparatus comprises a housing defining a chamber a first conduit and a second conduit. The first conduit extends into the chamber and has a first opening positioned in the chamber. The first conduit is fluidically connectible to the nozzle. The second conduit extends into the chamber and has a first opening positioned in the chamber. The second conduit is fluidically connectible to the pump. The first opening of the first conduit is positioned above the first opening of the second conduit. The chamber defines at least a selected volume between the height of the first opening of the first conduit and the height of the first opening of the second conduit.
