VWR UHP (Ultra High-Performance) pipettors operate
using the air cushion principle, i.e. the aspirated liquid
has no contact with the shaft or plunger of the pipettor.
The liquid is aspirated into disposable tips put on the
pipettor.
Pipettors are equipped with a four-digit counter display-
ing the set volume, and the aspirated volume is set by
means of the adjustment knob (fig. 1B). The pipettor
design allows the user to lock the volume setting.
