Technical Specification Sheet

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. We may have different adapters available depending on the rotor chosen with this centrifuge. If the selected rotor includes adapters that will not work for your application, please inquire.

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

Centrifuge Inspection and Recertification Checklist

Confirm the power supply output voltages match specified requirements for stable distribution to all internal components
Measure and verify voltages at PCB test points to ensure accurate power delivery and circuit integrity
Confirm rotor compatibility with the centrifuge model and check that rotor detection systems recognize the rotor type
Inspect the exterior for any cosmetic or structural damage that could affect performance or safety
Check the door mechanism alignment to ensure secure and smooth opening and closing
Inspect and replace the gas strut with an OEM part to maintain proper door support and safety
Examine the rotor chamber bowl for dents or damage and replace as needed to ensure safe operation
Replace and confirm full functionality of all lid lock switches to maintain secure closure
Inspect and lubricate the door lock mechanism, applying grease to the lid lock rail for smooth operation
Test compressor functionality (if applicable) to ensure proper operation and consistent temperature control
Conduct an 8-12 hour cycle test to validate consistent performance over prolonged use
Confirm rotor motor stability, check for unusual noise, and assess mechanical integrity during operation
Inspect the condensation drain and clear any clogs to prevent moisture buildup in the rotor chamber
Verify RPM accuracy using an NIST-traceable tachometer and perform calibration as necessary
Check the centrifuge error log to ensure zero recorded issues, confirming system reliability
