Turntable cylinder is 12″ (305 mm) diameter with 10-1/2″ x 6″ (167 x 152 mm) opening. Stainless steel self-lubricating ball bearing plates mounted on top and bottom permit the unit to rotate freely. Positioned bullet catches prevent uncontrolled rotation. Tumbler lock allows for the removal of the cylinder for sterilizing or autoclaving when necessary. 

Specimen container is placed inside the turntable cylinder and is then manually rotated clockwise or counterclockwise 180° to present the container to the rear opening for retrieval by technician. Service access to the unit is gained by unlocking and opening the door.
