High speed and easy operation. With its patented one-button control (Spincontrol S) and motorized lid lock, the Sigma 3-30KS centrifuge is remarkably easy to use, and it offers a broad range of options. LED illumination, a choice of six languages, a maximum RCF of over 70,000 x g and pleasantly low-noise operation are the factors that make this centrifuge, which fills the niche between standard and ultra centrifuges, so unique.
