The MTST KH22R is a benchtop high-speed refrigerated centrifuge built for small-volume separation work. It reaches a maximum of 18,600 r/min and 24,560×g, with a total capacity of 300 ml depending on the installed rotor.

Temperature is regulated across a -10°C to +40°C range with ±1°C accuracy, using a Freon-free compressor and a stainless steel chamber with a pre-cooling design. A microprocessor controller with touch panel and LED display lets operators set speed in RPM or RCF, configure run time, and store user-defined programs.

The compact footprint (350×625×370 mm) suits crowded bench space in molecular biology, clinical, and sample-prep labs that process microtubes and small-volume tubes.

How It Works

A brushless frequency-converter motor spins a fixed-angle or swing rotor to generate centrifugal force that separates sample components by density. The stainless steel chamber is cooled by a compressor to maintain the set temperature during a run, while selectable acceleration and deceleration profiles and timed operation (1 second to 999 minutes) help control the separation.
