MICROMAN ®
The Positive Displacement Pipetting Reference
How does it 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.

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.
