Volumetric Pipettes are designed to very accurately transfer a specific amount of solution. These pipets can only be used to deliver the volume of liquid for which it is calibrated. Volumetric pipets have narrow tips and a bulb-like expansion in the middle. The single calibration mark for these pipets is found in the tube section above the center expansion. Our volumetric pipets meet the most stringent ASTM standards for class A glassware available.
