Thermo Scientific ST40 Benchtop Centrifuge

The ST40 Centrifuge can be used to separate materials of different density or particle size in a liquid by generation of Relative Centrifugal Force such as human samples (blood, urine, and other body fluids) alone or with additives, other chemicals, and environmental samples. It has a maintenance-free induction motor that runs quietly with low-vibration operations at high speeds. The set speed can be reached in seconds. It can run at a speed of 300 rpm to 15,200 rpm (depending on rotor) with an unlimited runtime. The maximum RCF value is 25,314 x g. There is a user-friendly control panel to pre-set the speed, RCF value, runtime, temperature and a running profile. Various safety features include a lid with a view port and lock that only open when on and the rotor has reached a full stop, an electronic imbalance recognition, and an integrated rotor detection system ensuring no inadmissible speed settings are preselected. This rotor reaches speeds to 3,500 rpm.

Please confirm this rotor meets your application needs and request a different rotor, if necessary. Available rotors can be found in our Rotor Compatibility Guide.
