Abstract
A preprocessing device that carries out a dispensing process for aspirating a liquid sample accommodated in a sample container, and subsequently discharging and dispensing the sample into another sample container, the preprocessing device comprising: a dispensing nozzle; a dispensing nozzle tip detachably provided to the distal end of the dispensing nozzle; a disposal box in which the dispensing nozzle tip is disposed of after having been removed from the dispensing nozzle; and a cutting mechanism for cutting a dispensing nozzle tip inserted into a removal part, which removes the dispensing nozzle tip from the dispensing nozzle, from the longitudinal-direction side. This makes it possible to improve accommodation efficiency while suppressing accumulation of disposed-of dispensing nozzle tips.
