Globe Scientific's plastic serological pipettes are manufactured as a single piece. Unlike other brands that weld the separate tip and mouth pieces to the main body, our one-piece seamless design eliminates the weld points that trap liquid. The unique design provides faster fill and release rates, ensures a complete flow out of the sample and offers a higher degree of accuracy. The pipettes are supplied with an aerosol barrier plug that prevents both liquid and aerosols from contaminating the pipettors.
