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.
Claims20
An apparatus for testing centrifuge operation, the apparatus comprising:
- a tube sized to fit into a rotor of a centrifuge;
- a spring supported within the tube;
- a piston supported by the spring within the tube, the piston operable to exert a centrifugal force against the spring when the tube is spun in the centrifuge;
- and
- an indicator responsive to a displacement of the piston resulting from the centrifugal force.
An apparatus for testing centrifuge operation, the apparatus comprising:
- a frame configured for insertion into a centrifuge rotor;
- a flexible object supported by the frame, the flexible object operative to deform when the frame is spinning in the centrifuge rotor;
- and
- an indicator operative to indicate deformation of the flexible object resulting from the spinning in the centrifuge rotor.
