On-site cleaning and calibration

• Cornerload, repeatability and linearity tests
• "As Found" and "As Left" Data
• Cleaning of draft shield, housing, weighing pan, weighing chamber and door track
• Adjustment of the scales using a weight matching procedure to ensure accurate and consistent readings
• Re-leveling of the Balance/Scale

• 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.
