MICROMAN ®<br />
The Positive Displacement Pipetting Reference<br />
How does it work ?<br />
1. No air-to-liquid interface<br />
2. The desired volume is aspirated rapidly<br />
and completely<br />
3. The positive wiping action of the piston against<br />
the capillary wall assures accurate dispensing<br />
of even the most viscous sample and avoids any<br />
carry-over<br />

Improve accuracy and reliability<br />
with problem liquids<br />
Perfect solution for complete and rapid pipetting of viscous<br />
and dense liquids such as oil, syrup, cosmetic cream,<br />
liquefied food, paint, glycerol or buffers.<br />

100% protection<br />
against contamination<br />
Disposable capillaries and pistons prevent contact of the<br />
pipette with corrosive vapors or liquids.<br />
Built-in tip ejector prevents user contamination.<br />
No air-to-liquid interface protects the sample from<br />
aerosol contamination.<br />
Contamination-free pipetting of liquids such as DNA<br />
fragments, PCR templates, enzyme solutions or radio<br />
labeled components.<br />
