Intended Use
VWR® Pipettors are volumetric instruments designed to
measure and transfer liquids precisely and safely with the
use of disposable pipet tips. The pipettors operate on the
air-cushion principle (i.e., the aspirated liquid does not
come in contact with the shaft or plunger of the pipettor).
