ABSTRACT:
A plurality of glass slides having specimens such as blood smears disposed thereon are prepared for microscopic viewing by an apparatus which automatically applies preparation solutions to the slides such as stains and buffers and thereafter automatically drys the completed slides. The staining and buffering solutions are deposited evenly over the surfaces of the slides carrying the specimens by a timed operation of one or more electro-mechanically actuated aerosol dispensers which produce fine sprays of the desired preparation solutions. Simultaneously with the generated spray, the plurality of slides are rotated at a relatively slow rate to cause a uniform distribution of the spray particles on the slide surfaces. Following the staining and buffering mode, an automatic drying mode is initiated in which the plurality of slides are rotated at a relatively higher speed for a timed interval after which the apparatus automatically turns off and the completed slides may be removed from the apparatus.
