Sigma 4-16KS

The Sigma 4‑16KS refrigerated benchtop centrifuge excels with versatile rotor configurations and outstanding capacity. Large specimen volumes can also be processed efficiently thanks to the maximum capacity of 4 x 750 ml in a swing-out rotor or 6 x 250 ml a fixed-angle rotor. The especially smooth running ensures excellent and reproducible sedimentation results. With its versatile range of rotors, it is suitable for research labs, hospitals, universities and pharmaceutical labs, as well as cell culture and biotechnology applications.

What makes the Sigma 4‑16KS refrigerated benchtop centrifuge so attractive
The Sigma 4‑16KS is available with numerous swing-out and fixed-angle rotors as well as various buckets and adapters, including many biosafe configurations.
The extensive range of accessories can accommodate tubes and flasks from 0.2 ml to 750 ml as well as microtiter and deepwell plates.
The swing-out rotors can hold up to 3 litres (4 x 750 ml) or (for example) 16 x 50 ml tubes. The RCF values achievable with the configurations are best-in-class in this centrifuge segment. Highlights in the area of fixed-angle rotors include a 6 x 250 ml rotor with a maximum RCF of 13,131 x g and the ability to centrifuge 50 ml culture tubes at more than 23,000 x g.

This compact unit has intuitive operation and well-conceived features. The patented Spincontrol S one-knob controller provides superior operating convenience, safety and versatility. The acceleration and braking profiles (30 each) facilitate optimisation of separation runs and yields. Routine protocols can be stored with user-defined names and quickly retrieved from the integrated process library.
With automatic rotor identification, run time and speed monitoring, password-protected access to the controller and secure program storage, the centrifuge ensures uncompromising safety. The Sigma 4‑16KS also features a high-performance refrigeration system. Centrifuging at temperatures below 0°C is possible, depending on the rotor and the speed.

The Sigma 4‑16KS is also available as the Sigma 4‑16S unrefrigerated centrifuge and the Sigma 4‑16KHS refrigerated and heated centrifuge. An inert gas port is optionally available for this device series.
