  • Volumetric dispensing pipette
    Patent number: 4779768
    Abstract: A one-piece, blow molded pipette for dispensing precise volumetric quantities of fluid. The pipette includes a strategically positioned overflow reservoir and is uniquely configured so as to precisely control the flow paths of air and fluid within the pipette so as to positively preclude the accidental dispensing of a volumetric quantity of fluid greater than the volume of the tubular portion of the device.
