Sigma 1-14 – Compact High-Performance Microcentrifuge

Available in the Vietnam market only.

The Sigma 1-14 is a compact unrefrigerated microcentrifuge designed for fast and reliable separation of small-volume laboratory samples. With speeds up to 14,800 rpm, a maximum RCF of approximately 16,163 × g and a maximum capacity of 24 × 2 mL, it combines high centrifugal performance with a small laboratory footprint.

A wide selection of fixed-angle rotors enables the Sigma 1-14 to accommodate standard microtubes, PCR strips, microhaematocrit capillaries and spin-column filter tubes, making it suitable for molecular biology, clinical chemistry and general laboratory applications.
