NERO NRO-100
Single Channel Variable Volume Pipettor
Volume Range 10-100 uL · UniCal® Recalibration · µAir® Technology
The 10 - 100 uL window covers some of the most-used pipetting workflows in the modern lab. The NRO-100 delivers it with NERO's patented UniCal® recalibration in 30 seconds, µAir® zero dead-air space technology, and a 3-5N ultra-soft plunger that protects against RSI on long protocols.
Why The NRO-100?
Variable-volume pipetting at the 10 - 100 uL range demands two things conventional pipettes struggle to deliver simultaneously: precision across the full volume window, and ease of recalibration when drift appears. Most labs solve this by sending pipettes out for service quarterly — expensive and disruptive.
NERO's UniCal® technology eliminates that problem entirely. 0.6% accuracy and 0.2% CV at the 100 uL nominal is sustained through in-house recalibration that takes under 30 seconds and requires no disengagement of digits, no third-party service, and no instrument downtime.
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.
0.6% AT 100 uL
At full nominal volume, the NRO-100 delivers 0.6% accuracy and 0.2% 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.
"0.6% accuracy, 0.2% CV, 30-second recalibration." — NERO's UniCal® technology (Indian Patent No. 405607) lets a lab technician recalibrate a drifted pipette in-house in under 30 seconds — without disassembly, without third-party service, without instrument downtime.
