Abstract
A computer controlled pipetting system with a hand held pipettor and a control assembly. The pipettor has a motor driven pump for aspirating and dispensing liquid through a pipette which is inserted to the pipettor. The control assembly has a keyboard for controlling operation of the pipetting system. A calibration pipette is inserted into the pipettor for establishing reference signals corresponding to a selected density and temperature of a liquid which is aspirated into the calibration pipette by the pump. The reference signals are stored in a memory and subsequently used for aspirating selected quantities of liquid into a laboratory pipette which is inserted into the pipettor in place of the calibration pipette.
