Abstract
A rotor locator and centrifuge body locator includes a pair of locator arms that close about the rotor shaft and an alignment pin to center the rotor shaft. A registration mechanism rotates the rotor shaft and the centrifuge body until it reaches a known home position. A method of consistently registering the centrifuge body includes centering a rotor shaft of the body along a known center line and aligning the body to a home position both before and after centrifugation.
Claims5
A method for locating a centrifuge body, comprising:
- centering a rotor shaft of the body along a known center line;
- aligning the body to a home position;
- placing samples in one or more centrifuge buckets;
- centrifuging the samples;
- re-centering the rotor shaft along the known center line;
- re-aligning the centrifuge body to its known home position;
- and
- removing the samples;
- wherein centering the rotor shaft comprises constraining the rotor shaft with a pair of locator arms moveable between a first centrifuge operating position and a second locating position.
