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.

Calibration standards include: Wavelength Accuracy, Photometric Accuracy, and Stray Light Performance
We service spectrophotometers from various manufacturers including Agilent Technologist, Aurora Instruments, Auxilab, Biotek Instruments, Buck Scientific, Cecil Instruments, Datacolor, Hach, Jenway, Mettler Toledo, Thermo Fisher Scientific and X-Rite Inc.
Our calibration services typically use certified reference materials and follow standardized procedures to calibrate spectrophotometers accurately and reliably.

Frequency of calibration depends on various factors including accuracy requirements, operating conditions and the manufacturer’s recommendations.
Recommend calibrating pressure gauges at least once a year, and more frequently if the gauge is subjected to harsh conditions such as high vibration, extreme temperature, or exposure to corrosive substances.
Regular calibration helps ensure that the gauge is accurate and reliable, which is essential for maintaining product quality, process efficiency and safety
