ABSTRACT:
A unitary volumetric pipette for dispensing liquids is formed as a unitary structure made from components that have been precision made by an injection molding process and which are bonded together to create an extremely precision fluid dispensing device. The pipette includes a stem portion which is separately formed in an injection molding process and which is bonded, usually through heat bonding, to a bulb portion to complete the pipette. The bond between these two components is sufficiently strong to prevent separation of the pieces and is waterproof to prevent any leakage of fluid from the bulb portion.
