Product Information

Compact micro ultracentrifuges to fit your lab

Our micro ultracentrifuges from the CS-(F)NX Series, achieve extraordinarily high speeds of up to 1,050,000 x g (140,000 rpm). With these speeds, combined with fast acceleration and deceleration ramps, our micro ultracentrifuges ensure speedy separation of samples such as nucleic acids, proteins, protein complexes, vesicles and viruses in vessels between 0.2 – 30 mL.

Eppendorf micro centifuges: High-speed separation for your lab needs

Experience unparalleled efficiency with our CS-(F)NX Series. Designed to achieve speeds up to 1,050,000 x g (140,000 rpm), these compact micro ultracentrifuges ensure rapid and reliable separation of various samples, including nucleic acids, proteins, and viruses. Choose the perfect model to fit your lab’s needs and enjoy a stress-free work environment with noise levels below 45 dB(A).

Micro centrifuges with innovative features for enhanced efficiency

Additional features include the self-locking rotor system, which enables quick and easy rotor exchange within seconds and the innovative, non-contact imbalance sensor, which ensures safe operation while the possibility to balance samples by eye (up to 5 mm)* eliminates time-consuming sample balancing via scale.
The large touch display of our mini centrifuges with a quick start up time of only 8 seconds makes operation fast and easy, while providing enhanced security and compliance with user-based access control and documentation of runs. The ability to pre-program up to 20 programs supports multi-user labs as well as laboratories working in GxP/GLP compliance.

Find your perfect matching micro centrifuge model

Choose between two compact options to fit your space: a floorstanding model (Centrifuge CS150FNX) with a very compact footprint or a benchtop model (Centrifuge CS150NX) with standard power requirements for a flexible placement within your laboratory. Both devices have a low noise level of <45 dB(A), ensuring a stress-free work environment, even when working directly next to the device.

Balancing of samples is now easier than ever

You can simply balance your samples by visual check only (within 5mm difference between samples, excluding rotors S140AT, S110AT, S80AT3 and S50A). The powerful non-contact imbalance system monitors the vibration of rotor and drive shaft at all times. In case of unusual vibrations, the sensor is activated and the run is stopped immediately.

Tool-free rotor installation

The self-locking rotor system locks the rotor by centrifugal force, you can simply place the rotor on the drive shaft and that’s it! No need to lock the rotor with a rotor key or push a button to release it.
