How does a positive-displacement pipette work?

1. No air-to-liquid interface    

2. The desired volume is aspirated rapidly and completely

3. The positive wiping action of the piston against the capillary wall assures accurate dispensing of even the most viscous sample and avoids any carry-over

Improve accuracy and reliability with problem liquids

·Perfect solution for complete and rapid pipetting of viscous and dense liquids such as oil, syrup, cosmetic cream, liquefied food, paint, glycerol or buffers.

·Unique solution to avoid leakage when pipetting high vapor pressure liquids such as acetone, chloroform, alcohol, hexane or solvents.

100% protection against contamination

·Disposable capillaries and pistons prevent contact of the pipette with corrosive vapors or liquids.
·Built-in tip ejector prevents user contamination.
·No air-to-liquid interface protects the sample from aerosol contamination.
·Contamination-free pipetting of liquids such as DNA fragments, PCR templates, enzyme solutions or radio labeled components.
