Abstract
A micro-plate adapter for mounting a micro-plate onto a centrifugal separator rotor. The micro-plate has a sample injection hole portion containing a sample therein and as a box-like external wall. The adapter includes a bearing surface contacting a back bottom surface of the sample injection hole portion. A swing rotor for a centrifugal separator includes a rotor body attached to a driving shaft of the centrifugal separator and provided with a plurality of bucket storage portions; buckets all swingably engaged with the rotor body in the respective storage portions so that samples stored in the buckets are subjected to centrifugal separation by a centrifugal force generated by rotation of the swing rotor. Each of the buckets is formed to have a shape which adapts with a bottom surface of a micro-plate so as to contact with the back bottom surface of a sample injection hole portion of the micro-plate to bear a centrifugal load of the micro-plate. The swing rotor further includes a shell enclosing the rotor body and the buckets so as to rotate together with the rotor body and the buckets.
