Abstract: An apparatus for staining biological slides comprises a support housing; a slide conveyor assembly mounted within the support housing and including a slide support tray for holding a plurality of biological slides; a stain dispensing assembly within the support housing, having a plurality of dispensers adapted to be located above the slide support tray; and a stain removal assembly located within the support housing adjacent the dispensers, and including a fluid drain and a fluid evaporator. The slide tray is manually inserted and removed from the support housing, and is adapted to hold the slides throughout the entire staining process to minimize slide damage. Only two fluids, a stain and a buffer, are required and the entire procedure may be completed within seven minutes.

Abstract: An apparatus for the staining of a plurality of biological slides which comprises a slide support tray adapted to hold a plurality of slides in parallel position adjacent each other, a support tray rack assembly adapted to slidably receive said support tray, said rack assembly including a stain composition dispensing assembly providing a plurality of dispensing spigots, said spigots mounted on said rack assembly in overhead relation to said support tray when said support tray is fully received within said rack assembly, and means for removing excess stain composition and drying said slides, wherein said support tray is adapted for removable insertion and securement within said rack assembly. The apparatus of the present invention is contained within a central housing which also includes a single slide staining apparatus comprising a reciprocable slide support tray slidably connected to a separate rack assembly.
