Small centrifuges

Our small clinical centrifuges accommodate most common blood collection tubes.

Compact, low-speed centrifuges are ideal for separating whole blood components — serum, plasma, buffy coat and red blood cells — as well as other body fluids.

Key Features of Sigma Centrifuges

Energy Efficiency, Maintenance-Free Design, and a Comprehensive Product Family.

Eco Mode 

Energy-efficiency

Our laboratory centrifuges are built to last and easy to repair. They are reliable, powerful and user-friendly. Improving the working environment in our customers' labs matters to us as much as advancing energy efficiency.

Some cooled models feature an energy-saving ECO mode (standby). After a user-defined idle time, the centrifuge switches to standby if unused. Besides saving energy, this improves the lab atmosphere by turning off the refrigeration and cutting noise significantly.

Sigma comfort rotor black pins no-grease grease-free

Your comfort in centrifugation

No more greasing

Cleaning and maintaining centrifuges and accessories is essential for safe, long-term operation and optimal separation. With swing-out rotors, the pins carrying the buckets must be greased regularly. Irregular or missing greasing hampers bucket swing-out and causes imbalance.

Thanks to the new Sigma Comfort coating, the black pins of Sigma Comfort rotors no longer need greasing. Rotor and buckets work together smoothly for years — without regular greasing.

Maximum work convenience with minimum operating noise.
The Sigma 1‑7 is designed for the separation of blood and urine specimens in medical practices and small labs, and due to its strong performance it is also used in environmental analytics, schools and universities.

The Sigma 1‑7 compact benchtop centrifuge is especially good in delivering exact results in a very short time. With these attributes combined with convenient, intuitive operation and the motorised lid lock, which enables effortless closing of the centrifuge, it offers more than comparable devices in its segment.

What makes the Sigma 1‑7 benchtop centrifuge so attractive?
The Sigma 1‑7 benchtop centrifuge is the only one in its segment that supports up to ten saved programs. This allows routine protocols to be stored and work processes to be optimised. In operation this small centrifuge runs with especially low vibration, quietly and pleasantly.

The perfectly matched fixed-angle rotor of the Sigma 1‑7, with a maximum capacity of 6 x 15 ml, is well suited to meet the demands of small volumes of specimens. The maximum RCF of 6,153 x g and the short braking and acceleration times of this small centrifuge allow separation times to be shortened considerably.

High performance with a new design

The Sigma 2-7 compact laboratory centrifuge arose from the experiences and desires of our customers. The technical features of this centrifuge are impressive: stainless steel bowl, imbalance switch, motorised lid lock, innovative run display with blue LEDs, and process reliability. The centrifuge is also very quiet in operation. Specimens are only slightly warmed, which is important for blood specimen tubes in particular. Together with a versatile, modular swing-out rotor, the foundation is laid for a successful career in many laboratories.

The benchtop centrifuge is available with numerous swing-out and fixed-angle rotors, along with various buckets and adapters. The extensive range of accessories can accommodate tubes and flasks from 1.5 ml to 100 ml as well as microtiter and deepwell plates.


The Sigma 2‑7 is also available as an IVD model. For cytocentrifugation, also ask the Cyto version.
