Abstract
Abstract The dryer of the present invention comprises a substantially rectangular housing open at its front end and its rear wall is provided with one or more openings for the ingress of air. The front end is adapted to receive and hold in locked position a microscope slide tray, the locking being provided by a pair of slidably mounted legs carried by the front ends of the housing side walls. The upper ends of the legs are attached to a transverse shield. An electric fan is mounted in the rear portion of the housing and an electric light bulb, or other suitable heat source, is mounted in the upper portion of the front portion of the housing. A transverse heat and air baffle or shield is mounted intermediate the bulb and top of the housing.
