Sigma 2-16KHL

Category: Brand:

The Sigma 2‑16KHL refrigerated and heated model is the preferred choice for use with specimens whose viscosity needs to be reduced during centrifugation. It is also used in molecular biology to improve cell viability. Thanks to its compact design, it fits in every lab.

What makes the Sigma 2‑16KHL benchtop centrifuge so attractive
With a wide range of fixed-angle and swing-out rotors, this all-purpose centrifuge can hold PCR tubes, test tubes, round-bottom tubes, culture tubes and microtiter plates. This extensive range is rounded out by a haematocrit rotor.
The Sigma 2‑16KHL provides extraordinary capacity with 4 x 100 ml in a swing-out rotor or 6 x 50 ml in a fixed-angle rotor.

The Sigma 2‑16KHL has a high-performance, precisely adjustable refrigeration system with a temperature range of –10°C to +60°C. The Rapid Temp quick cooling function allows the centrifuge chamber and accessories to be pre-cooled to a defined temperature. This ensures optimal protection of specimens against heating.

Up to 50 different routine protocols can be stored in program memory and easily retrieved. Ten selectable acceleration and braking curves support the optimisation of separation processes.
