Centrifuges

  • Calibrated by checking the rotation speed using a NIST-Traceable photo-tachometer.
  • Units equipped with timing devices are also tested by direct comparison with NIST-Traceable stopwatch.
  • Temperature verification of refrigerated centrifuges are available on most units.
  • On all units, we perform a safety inspection of the instrument prior to beginning work and general cleaning afterward.
  • A calibration label is affixed to the centrifuge and a calibration report is provided.
