Abstract:
1. A combination of a pipette and a pipette cleaning apparatus, comprising: the pipette comprising a pipetting needle including a suction and ejection opening at a tip thereof; and the cleaning apparatus comprising a concave portion including a cavity, said cavity being internally bounded by an inner circumferential surface extending from a top opening to a lower end of the cavity, said cavity being configured to receive said pipetting needle of the pipette positioned therein for cleaning of the pipette, said pipetting needle and said cavity being mutually dimensioned so that pipetting needle is receivable within the cavity with the tip positioned proximate to said lower end such that a cleaning liquid passed through an inside of the pipette and ejected from the tip strikes the inner circumferential surface of the cavity and bounces therefrom to splash against an outer wall surface of the pipetting needle over a sufficient length thereof to effectively clean the outer wall surface, said inner circumferential surface presenting a continuously downward tapering configuration from said top opening to said lower end of the cavity.
