COLO.SCIENCE – NICHIPET EX PLUS II
100–1000 µL variable micropipette Nichipet EX Plus II (single-channel)
The Nichipet EX Plus II 100–1000 µL variable micropipette is an original Nichiryo instrument made in Japan. It is built for work with organic solvents: a perfluoro-rubber O-ring and solvent-resistant plungers come as standard.
Volume is set from 100–1000 µL in 1 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 100–1000 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.
Nichipet EX Plus IIFor organic solvents – perfluoro-rubber O-ring as standard.
Other Nichipet EX Plus II models: 0.1–2 µL · 0.5–10 µL · 2–20 µL · 10–100 µL · 20–200 µL · 0.5/1–5 mL · 1–10 mL
Key features
- Perfluoro-rubber O-ring as standard – small volume growth against acids, alkalis, ammonia water, esters, furan and amines
- PTFE in the airtight chamber; plungers in solvent-resistant materials
- Ceramic plunger against corrosion (200 µL – 10 mL)
- Autoclavable at 121 °C for 20 minutes; non-grease design
- Easy calibration with the enclosed jig; one-touch volume lock
Where 100–1000 µL precision matters
- Buffers, media and reagent preparation
- Sample transfer in analytical chemistry
- Routine liquid handling in clinical and QC laboratories
