NRO-50
The Smart Lab NRO-50 is an ergonomic, single-channel variable volume micropipette with a range of 5 µl to 50 µl. It is a professional laboratory instrument designed for high-precision liquid handling, featuring a fully autoclavable body and patented calibration technology for reliable use in molecular biology and clinical diagnostics.
Description
Description
The NRO-50 is part of the premium NERO® product range, renowned for its award-winning design and exceptional ease of use. It features a lightweight, chemical-resistant polycarbonate housing that ensures long-term durability while reducing hand fatigue during repetitive pipetting tasks. The pipette is fully autoclavable at 121°C and 15 psi for 15–20 minutes without disassembly, supporting sterile workflows in sensitive pathology and microbiology laboratories.
Main Features
µAir® Technology
This patented technology minimizes the “dead air space” between the piston and the tip cone. By reducing air compression, it delivers outstanding accuracy and precision, even under changing laboratory conditions.
UniCal® Calibration System
The innovative UniCal® mechanism enables fast, single-step calibration directly in the laboratory. Calibration can be performed without disengaging the volume digits or dismantling the plunger, reducing downtime and maintenance costs.
Precise Volume Lock Mechanism
Equipped with a spring-and-ball locking system that provides a distinct “click” at each volume adjustment. This ensures secure volume settings and prevents accidental changes during operation.
Lightweight Ergonomic Design
Engineered for maximum user comfort, requiring minimal plunger force (approximately 3–5 N for the first step). The soft-grip handle supports smooth, single-handed operation during extended use.
Universal Tip Cone Compatibility
The precision-designed tip cone is compatible with most internationally standardized pipette tips, offering flexibility and improved laboratory efficiency.
Large 4-Digit Volume Display
A clear, high-visibility display allows for accurate volume setting and helps minimize reading errors.
Integrated Tip Ejector
A built-in tip ejection system applies optimal force for easy, one-handed tip removal, reducing thumb strain and minimizing the risk of cross-contamination.
