Abstract
The present invention determines whether or not a mounted tip and a dispensing amount match with each other in order to prevent contamination in a dispensing device. The present invention is provided with a pipette mechanismthat performs suction and discharge, a motorthat drives the pipette mechanism, and a pressure sensorthat detects a pressure of the pipette mechanism. A dispensing tipis mounted to the pipette mechanism. A control computercontrols the motor, drives the pipette mechanism in a suction or discharge direction, and determines a type of the dispensing tipon the basis of a difference in pressure waveform detected by the pressure sensor
