Abstract
A replaceable pipette tip is described which forms a tight sealing engagement with the working end of a pipette. In one embodiment for a pipette tip a cam surface is provided to enable a slight tip rotation when the working end of a pipette is inserted in the tip. A particularly effective and reliable seal is obtained when a pipette tip having integrally molded ring seals and a cam surface is employed with a pipette working end having a resilient insert located to form an effective seal with the molded rings.
