Abstract
A device is disclosed for removing a disposable tip from a pipette. The device includes an elongated shaft with a flattened push-button at one end and an elongated groove. Elongated projections extend inwardly from each side of the groove. A guide member extends outwardly from the pipette. The guide member includes opposed longitudinal notches configured to mate with the projections along the sides of the groove in the shaft and includes an end portion configured to slide within the groove in the shaft. A sleeve is attached to the second end of the shaft. The sleeve is configured to slide over the exterior surface of the pipette. A spring is disposed within the shaft groove and biases the shaft and attached sleeve into a first position where the end of the pipette is exposed so that a disposable tip can be attached to it. When the push-button is depressed, the shaft and sleeve move downwardly along the pipette to push off the disposable tip.
