ABSTRACT:
A positive displacement pipette tip in which a one-piece piston having a tapered end slides within a capillary tube having a matching taper. The capillary tube includes a collar with a snap ring for attachment to the body of a pipette. The piston includes a two-prong fork-like coupling for attachment to the plunger of the pipette. Attachment of the pipette tip can be made without physical handling, and ejection is achieved by an over extension of the pipette plunger. The pipette tip has a precision outlet orifice for drawing and dispensing liquid, and is suitable for DNA research such as that involving polymerized chain reactions.
