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. The ergonomic pipette tip includes molded-in expansion joints and/or the addition of a second elastic material to decrease the amount of force necessary to radially expand the entrance to the pipette tip when the pipetter barrel is guided and stability oriented towards the sealing region of the pipette tip. Also disclosed is an ergonomic adapter with similar features as the tip that can also be mounted to the barrel of the pipetter and attached to a standard pipette tip or a combination of tips. Therefore, the relatively small axial forces necessary for mounting and ejecting the new ergonomic tip and adapter can substantially help to reduce the hand and thumb forces, that due to repeated use, will sometimes result in repetitive stress injury.
