Samples which are to be processed or analyzed in the laboratory are placed in small vials or cuvettes. Groups of cuvettes are placed in arcuate carriers, which are then mounted about the periphery of a rotator head. The rotator head has two selectable motions. It can rotate at a higher speed on a vertical axis for an automatically timed period, thereby subjecting the samples to mild centrifugal settling or sedimentation, or it can rotate at a lower speed about an inclined axis, thereby subjecting the sample to mild agitation or mixing.

Adjustable rotator for fluid samples

A controlled depth fluid aspiration cannula is disclosed comprising an elongated tubular member terminating at the distal end with a wall and terminating at the proximal end with attachment means to provide a sealing fitment for a flexible conduit. Radially disposed orifices are positioned near the distal end, and a radially extending flange is positioned between the ends of the tubular member to provide controlled depth aspiration of fluid.
