Key engineering features
Rapid cooling
Under the stated test conditions, the chamber cools from 25 °C to 4 °C in approximately six minutes using an environmentally considerate refrigerant.
Intelligent touchscreen operation
HD touch-panel control with storage for 99 custom programs and USB data export supports method recall and centrifugation-record documentation.
High- and low-speed flexibility
Interchangeable angle and swing-out rotors support high-speed microtube processing and lower-speed, higher-capacity workflows with vessels up to 250 ml.
Programmable, stable operation
Ten acceleration/deceleration levels, soft start/stop control, three-stage rubber vibration absorption and automatic balancing protect samples and support noise levels up to 60 dB(A).
NCP rotor and ceramic chamber technologies
Selected carbon nano-polymer composite rotors combine low mass, high strength, low thermal conductivity and corrosion resistance. The nano-ceramic chamber coating adds protection against corrosion and rust.
Laboratory applications
Clinical laboratoriesSeparation of blood fractions, urine sediments and other validated clinical specimens.
Molecular biologyPelleting cells, nucleic-acid preparation steps and general microtube workflows.
BiochemistryClarification, phase separation and preparation of samples before downstream analysis.
Bioengineering & agricultureProcessing of cell suspensions, culture samples and research specimens.
Rotor, tube and speed must always be selected according to the validated method, sample characteristics and tube manufacturer's limits.

Operational and safety functions
Emergency lid release
Provides controlled access to samples after a power interruption, following the operating manual and only after the rotor has fully stopped.
Multiple operating modes
Timed, inching, differential-time and gradient centrifugation modes support routine separation and more specialised refrigerated protocols.
Ergonomic rotor workflow
A one-turn NCP rotor-lid design, aerodynamic buckets, three-stage rubber shock absorption and automatic balancing support convenient, stable operation.
