Refrigerated microcentrifuge | Sigma 1‑14K | Small refrigerated laboratory centrifuge for research and universities

The Sigma 1‑14K centrifuge has a small footprint, fits in every lab, and fulfils the most stringent technical requirements. Its strong performance and large range of rotors are unique:

Two fixed-angle rotors provide a maximum capacity of 24 x 1.5/2.0 ml. Thanks to rotors for PCR strips, microhaematocrit capillary tubes and filter tubes, the Sigma 1‑14K is an all-round laboratory centrifuge suitable for a wide variety of applications. It is popular for molecular biology applications such as DNA, RNA and protein isolation, clinical chemistry, and in research labs and food labs, universities, and the pharmaceutical industry.

What makes the Sigma 1‑14K refrigerated mini centrifuge so attractive
The handy Sigma 1‑14K mini centrifuge combines effective performance with reliability. It is pleasantly quiet even at maximum speed, has wonderfully short braking times, is easy to use, and can be closed effortlessly thanks to a motorised lid lock. Customers also appreciate the price/performance ratio.

The Sigma 1‑14K is the most compact refrigerated centrifuge commercially available and easily achieves +4°C at maximum speed.

The Sigma 1‑14K is also available as the Sigma 1‑14 unrefrigerated centrifuge.
