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.
