Refrigerated floor-standing centrifuge
Sigma 8KBS
Medical device with new certificate
The Sigma 8KBS refrigerated floor-standing centrifuge is a medical device according to Regulation (EU) 2017/745, Class IIa for the separation of blood components for transfusion medicine and has been specifically developed for use in blood banks and transfusion facilities. With a maximum capacity of twelve blood bag systems per run, it enables efficient processing of large specimen volumes. The centrifuge reliably delivers excellent and reproducible sedimentation results thanks to its very smooth running.
Along with its outstanding performance characteristics, the Sigma 8KBS features impressive energy efficiency and perfectly matched components. Intuitive operation and the ergonomic loading height of just 88 cm simplify daily work in the lab and make the Sigma 8KBS one of the most popular blood bank centrifuges on the market.
What makes the Sigma 8KBS floor-standing centrifuge so attractive
Users appreciate the Sigma 8KBS as an efficient, high performance blood bank centrifuge. With maximum RCF up to 5,394 x g, the patented Spincontrol S single-knob control and ergonomic lid opening, it is the ideal device for intensive daily use.
This floor-standing centrifuge is among the most compact units of its class and is pleasantly quiet. It ensures a pleasantly quiet working environment with a noise level of 54 db(A)*.
The high-performance refrigeration system can be adjusted precisely over a temperature range from -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, which is particularly important when working with pre-chilled blood pouches.
