MAGNETSCHEIDEVERFAHREN UND -VORRICHTUNG BEI GEBRAUCH EINER PIPETTE.

摘要

A magnetic material attracting/releasing control method makes use of a pipette device (P) sucking a liquid from or discharging a liquid into a container (1). A magnet body (M) or bodies are provided in a liquid suction line of the pipette device (P), and any magnetic material (3) contained in liquid sucked into the liquid suction line by magnetic force are deposited on the internal surface of the line. The magnetic material (3) is released and discharged together with liquid from the liquid suction line to a state where the effect of the magnetic force generated by the magnet body (M) is cut off.
