Multiple function centrifuge apparatus with index plate and method

摘要

A multiple function centrifuge for use in the centrifugation of sets of centrifugation containers within preselected size ranges and centrifugation speeds. The centrifuge rotor is configured with a plurality of receptacle sets therein, each set having a preselected size to receive the corresponding size of centrifugation container. An index plate has a single set of access ports therethrough. The orientation of the access ports is coordinated with the placement of the receptacle sets to limit placement of centrifugation containers to a single receptacle set. Once a particular size of centrifugation container has been selected and inserted into the appropriate receptacle in the rotor, the index plate automatically blocks placement of centrifugation containers into any other receptacle. The motor is a multispeed motor to allow the operator to select the appropriate centrifugation speed and duration as a function of the liquid undergoing centrifugation.
