Refrigerated benchtop centrifuge
Sigma 2-16KL
Easy operation, all-purpose
The Sigma 2‑16KL is the right answer for virtually every task in everyday lab work. This all-purpose centrifuge is versatile in use and fits in every lab thanks to its compact design. With an extensive range of rotors and accessories and high RCF values up to 21,913 x g, it is suitable for a wide variety of applications.
What makes the Sigma 2‑16KL 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 2‑16KL 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 2‑16KL has a high-performance, precisely adjustable refrigeration system with a temperature range of –10°C to +40°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.

Sigma centrifuge tables are available in six different sizes. Matched to the corresponding centrifuge dimensions, they combine convenient work height with an optimally calculated footprint. The tables are made from coated sheet steel and are equipped with a storage compartment (with two doors) and a convenient pull-out shelf. Lockable castors allow the centrifuge tables to be easily moved and positioned in the laboratory.
