Abstract
An ergonomically designed pipette tip that can be securely mounted to a barrel of a pipetter yet is designed to substantially reduce the axial force necessary to install and eject the pipette tip from the pipetter thus reducing the injuries resulting in repetitive stress injury to the thumb and hand. The new ergonomic pipette tip incorporates a separate sealing member constructed from an elastomer that is coupled to the more rigid and chemically inert elongated tubular member that becomes the receptacle for transferring the fluid sample aspirated by the pipetter. The new elastomeric sealing member allows for greater sealing capability or squeeze between the pipetter barrel and the new pipette tip while lowering the coefficient of friction between the mating parts, thus decreasing the axial ejection forces require to overcome the breakaway friction between the new ergonomic pipette tip and the pipetter.
