Low Insertion Force Tip/Mandrel
US Patent:
6973845, Dec 13, 2005
Filed:
Jan 18, 2001
Appl. No.:
09/764691
Inventors:
David W. Bell - Anaheim CA, US
Assignee:
Beckman Coulter, Inc. - Fullerton CA
International Classification:
G01N001/00
US Classification:
7386414
Abstract:
A pipette assembly for automatic pipetting machines including a stepped mandrel and tip for providing a minimum contact seal between the pipette tip and mandrel. The mandrel includes a first cylindrical portion with a first exterior diameter and a second cylindrical portion with a second exterior diameter. Raised bands on the first and second cylindrical portions contact the interior wall of the pipette tip to form seals. Because only a portion of the mandrel, specifically the seal portions, contacts the pipette tip, lower forces are required to insert the tip onto the mandrel.
