Abstract

A rotor adapted for containing a plurality of sample tubes and for retaining the contents of such tubes if any should rupture while in the rotor. The rotor includes an upper shell and a lower shell connected by a central hub interposed therebetween. Provision is made for coupling the hub to a drive shaft. The upper shell has a substantially frustoconical shape and a recessed top surface. The top surface has a form generally corresponding to the interior of an inverted frustum. A plurality of sample tubes are disposed in a circular locus in the top of the rotor. The lower shell of the rotor has a bottom formed with upturned inwardly sloping conical sides. The sides are disposed such that their uppermost portion is proximate the upper shell. In the event that one or more tubes ruptures while in the rotor, the contents will be retained in the lower shell rather than spilling into the rotor chamber.
