Abstract

A pipette comprises a housing extending from a lower end to an upper end and a neck extending from the lower end of the housing and configured to hold a pipette tip. A stroke rod comprising an upper end and a lower end is configured to displace a tip plunger in the pipette tip. A drive apparatus is configured to displace the stroke rod to: (1) aspirate a liquid specimen into the pipette tip held on the neck; and (2) to eject the specimen from the pipette tip by means of a tip plunger positively connected to the stroke rod. At least one locking sleeve is arranged coaxially with the stroke rod and configured to be displaceably guided toward the stroke rod in the housing The locking sleeve is configured to inhibit release of a tip plunger from the stroke rod.
