Abstract

Pipette mandrel, pipette assembly and method for connecting a pipette mandrel to a pipette tip A pipette assembly (10) for automatic pipetting machines including a stepped mandrel (30) and pipette tip (12) for providing a minimum contact seal between the pipette tip (12) and mandrel (30). The mandrel (30) includes a first cylindrical portion (42) with a first exterior diameter and a second cylindrical portion (44) with a second exterior diameter. Raised bands (40, 46) on the first and second cylindrical portions (42, 44) contact the interior wall of the pipette tip (12) to form seals. Because only a portion of the mandrel (30), specifically the seal portions, contacts the pipette tip (12), lower forces are required to insert the pipette tip (12) onto the mandrel (30).
