Refrigerated and heated benchtop centrifuge
Sigma 3-30KHS
Outstanding high speed performance
This high speed centrifuge combines innovative technology with many decades of experience in the field of high speed laboratory centrifuges.
Positioned between laboratory centrifuges and ultracentrifuges, this refrigerated and heated centrifuge features outstanding performance characteristics and excellent value for money.
High RCF values of more than 70,000 x g enable fast separation, even with microscopic particles and cell fragments. This makes the Sigma 3‑30KHS especially suitable for high speed applications in fields such as cellular biology, molecular biology, diagnostics and clinical biology, nanotechnology, research and genetics – especially for specimens whose viscosity must be reduced during centrifugation.
What makes the Sigma 3‑30KHS high speed centrifuge so attractive
The special drive system of the Sigma 3‑30KHS is specifically designed for use at very high speeds. This concept allows the high speed centrifuge to achieve RCF values above 70,000 x g with microlitre tubes.
The temperature adjustment range of the refrigerated and heated high-speed centrifuge is –20°C to +60°C.
A total of 20 rotors are available, along with a broad range of accessories. The tube capacities extend from 0.2 ml to 94 ml in fixed-angle rotors or 0.2 ml to 100 ml in swing-out rotors. Microtiter and deepwell plates can also be centrifuged.
