Abstract: A centrifuge calibration apparatus (10) configured to be spun in a centrifuge and to provide an indication (25) of performance of the centrifuge. Spinning of the apparatus in the centrifuge causes a piston (14) to exert centrifugal force to compress a spring (22), thereby generating relative movement between a pointer (24) and a scale (26). The scale may be calibrated in units of G-force or RPM. A ratchet mechanism (40) holds the pointer at its most displaced position upon completion of the spinning and removal of the apparatus from the centrifuge.
