Sigma 4-5KL

Refrigerated benchtop centrifuge
Sigma 4-5KL

A top performer for high throughput

The high-performance Sigma 4-5KL laboratory centrifuge is designed for throughput and capacity. The hight torque enables especially short acceleration times and makes laboratory processes efficient. This centrifuge is recommended for applications in clinical diagnostics and for life sciences applications

The refrigerated version Sigma 4-5KL, with a temperature adjustment range of -10°C to +40°C, is recommended for the protection of specimens with especially sensitive limit temperatures.

The Sigma 4‑5KL also boasts a low noise level and an extensive range of accessories. Up to 50 different routine protocols can be stored in program memory and easily retrieved.

What makes the Sigma 4‑5KL benchtop centrifuge so attractive
The Sigma 4-5KL refrigerated centrifuge is recommended for all applications in which the room temperature must be maintained. To save energy and reduce costs, the refrigerated centrifuge offers the ECO mode feature. After a user-settable time, the centrifuge automatically switches to standby mode if it is not being used. Along with being energy efficient, this improves the working atmosphere in the lab by switching off the refrigeration to significantly reduce the noise level. The refrigerated centrifuge has a very small footprint and offers good value for money.

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.
