Both types of rotators can be mounted and removed from the base power unit and used interchangeably. The Model 202 can be operated with a single rotator or, for maximum utility, with two rotators of either design simultaneously. The rotation speed is adjustable from three to 20 RPM through a variable speed controller on the front of the unit. The compact ambient rotator has a footprint of 13 x 31 inches and weighs 40 pounds (without rotator) enabling it to be transported in and out of a fume hood. Robbins Scientific Corp.
