Of all the medical equipment found in medical laboratories, the Medical Centrifuge is one of the most common one. Almost all laboratories will have a requirement for a centrifuge, be it in a hospital, a medical laboratory or a private practice of some kind.

A medical centrifuge is an instrument that spins samples at a very high speed, forcing heavier particles to collect at the bottom of a tube. These instruments are used for separating the cellular components of blood from the liquid, so the liquid can be used for testing, and they vary in size, capacity and speed capability. They usually have a speed capacity of 0 – 2000 rpm’s and can hold tubes ranging in size from 5 ml to 50 ml.

The terms “calibration” and “adjustment” are often misunderstood, and sometimes even considered the same process. Both are essential for the proper functioning of equipment, to ensure greater accuracy of measurement and consistent readings, but they are unique processes.

Calibration

• The process in which you compare the values or measurements indicated by certain instrument or system against those indicated by a standard (Calibrator), under controlled test conditions.

• The output and accuracy of the standard are known, so the measurement of a specific quantity can easily be compared with comparable measurements from the IUT. A calibration report is then created, which includes details like the pass/fail results of each parameter, operating or test conditions, industry specifications, acceptable tolerances, etc.

Aside from proper maintenance all medical instruments that make use of electronic components for accuracy will need calibration one way or another. Routine equipment calibration is needed to ensure grayscale accuracy.  Maintaining properly calibrated equipment provides measurement consistency, reduced measurement errors and measurement accuracy.
