Refrigerated Centrifuge : SIGMA 4-5KL (max capacity 4 x 750 ml, max. RCF 20,376xg)
Refrigerated benchtop centrifuge Sigma 4-5KL
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.
