Refrigerated floor-standing centrifuge Sigma 8KS

Performance-oriented and large capacity up to 12 litres

The Sigma 8KS is a refrigerated floor-standing centrifuge that is ideal for all-purpose use in the industrial and research sectors. This high-performance centrifuge features impressive capacity of up to 12 x 1,000 ml in a swing-out rotor or 6 x 1,000 ml in a fixed-angle rotor. With a maximum RCF of 20,461 x g, even demanding separation processes can be handled efficiently. Particularly thanks to the ability to use large-volume fixed-angle rotors with high RCF, the Sigma 8KS cover a distinctly broader spectrum of applications compared to competitive units.

What makes the Sigma 8KS floor-standing centrifuge so attractive
For the sedimentation of relatively large quantities of liquids, the Sigma 8KS delivers reliably reproducible results together with impressively smooth running.
The numerous buckets and adapters can accommodate tubes and flasks from 1.5 ml to 1,500 ml, as well as microtiter plates and deep-well plates. Two 6-position swing-out rotors accommodate standard 1,000 ml and 1,500 ml flat-bottom flasks. Along with the large-capacity fixed-angle rotors, many users appreciate the ability to use a swing-out rotor either with or without a windshield. Energy savings exceeding 63% can be achieved with a closed windshield due to the lower drag. It also reduces heat transfer to the laboratory environment as well as the running noise level.

The Sigma 8KS has a fast, precisely adjustable refrigeration system with a temperature range of –20°C to +40°C. The Rapid Temp quick cooling function allows the centrifuge chamber and accessories to be pre-cooled to a defined temperature. In the other direction, fast heating is also possible.

Intuitive operation with the Spincontrol S premium controller, automatic lid opening and the ergonomic loading height of just 88 cm simplify daily work in the lab and make the Sigma 8KS one of the most popular large-volume centrifuges on the market.
