COLO.SCIENCE – NICHIPET AIR
2–20 µL variable micropipette Nichipet Air (single-channel)
The Nichipet Air 2–20 µL variable micropipette is an original Nichiryo instrument made in Japan. It is among the world’s lightest micropipettes, with up to 70 % less stroke load – made for long pipetting series.
Volume is set from 2–20 µL in 0.02 µL increments. Accuracy and precision below are Nichiryo values measured with original Nichiryo tips.
Same range, 5 Nichiryo lines – choose by your work
All lines below cover 2–20 µL, are made in Japan and use original Nichiryo tips. They differ in weight, resistance and durability – pick the line that fits how often and with what liquids you pipette.

Key features
- Among the world’s lightest micropipettes – approx. 70 g
- Up to 70 % less stroke load than conventional models
- Entire body autoclavable at 121 °C for 20 minutes
- Volume setting independent of the push button – no volume shift while pipetting
- Removable tip ejector, also for thin test tubes
Where 2–20 µL precision matters
- Small reagent volumes in molecular biology
- Serial dilutions at low volume
- Sample loading for electrophoresis
