Positive displacement pipettes offer an alternative to air displacement models. These products are designed for use with high vapor-pressure applications, such as when dispensing alcohols, acetone and hydrocarbons. The piston of the pipette remains in contact with the liquid that’s aspirated, so there is no air between the piston and the liquid. This type of pipette provides accurate and reproducible results even with high density media. We offer BrandTech positive displacement pipettes in various volume sizes.
