NERO NRO-F-25
Single Channel Fixed Volume Pipettor
Fixed 25 uL Dispense · UniCal® Recalibration · ISO 8655 Certified
Repetitive identical-volume protocols — rapid test kits, diagnostic plate fills, master mix distribution — lose throughput and accuracy when operators dial volume on every transfer. The NRO-F-25 is purpose-built for this workflow: a fixed 25 uL dispense, a 3-5N ultra-soft plunger, and UniCal® recalibration in under 30 seconds.
Why The NRO-F-25?
Fixed-volume pipetting solves a problem variable-volume pipettes don't: it eliminates the volume-drift risk entirely. Rapid test kit manufacturing, diagnostic QC labs, and high-throughput plate filling all benefit from a pipette where the operator cannot accidentally change the dispense volume mid-shift.
The NRO-F-25 delivers fixed 25 uL dispenses with 0.8% accuracy and 0.4% CV at nominal, calibrated against DIN EN ISO 8655-2 at Microlit's NABL ISO 17025 lab. Combined with NERO's UniCal® technology, an operator can recalibrate the pipette in under 30 seconds without disengaging digits or sending the instrument out for service.
UniCal® CALIBRATION
NERO's patented UniCal® technology lets you recalibrate in under 30 seconds in a single step — no disengaging digits, no third-party service, no instrument downtime.
0.8% AT NOMINAL
At 25 uL, the NRO-F-25 delivers 0.8% accuracy and 0.4% CV per the catalog spec, verified against DIN EN ISO 8655-2 at Microlit's NABL-accredited ISO 17025 lab.
µAir® ZERO DEAD-AIR
NERO's µAir® technology eliminates the dead-air space between piston and liquid — delivering accuracy and repeatability that conventional micropipettes cannot reach, especially at sub-microliter volumes.
3-5N PLUNGER FORCE
Ultra-soft plunger requires only 3-5N of force for the first stop — the lightest pipetting experience in the industry, designed to eliminate repetitive strain injury (RSI) on long protocols.
"Fixed 25 uL, 0.8% accuracy, recalibration in 30 seconds." — The NRO-F-25 is built for production-scale repetitive workflows where volume consistency is non-negotiable and downtime for calibration is unaffordable.
