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. An improved pipette tip that includes the addition of an elastomeric material and cooperative means for insuring uniform interference and depth of penetration of the pipetter barrel as successive barrels are inserted and ejected. Also disclosed is an improved multiple-tip configuration with similar features that can be mounted to multiple barrels of a multi-pipetter as one tip instead of 8 or 12 individual tips. The addition of the elastomeric material allows for better sealing and eliminates alignment issues, high installation and ejection requirements while reducing the hand and thumb forces that due to repeated use will sometimes result in repetitive stress injury.
