Abstract: A microscope slide module for processing samples captured in gasketed compartments of slide assemblies which include gasket slides. The microscope slide module includes a baseplate having a number of recesses for holding the gasket slides in fixed position, a coverplate which attaches to the baseplate, such that slide assemblies including gasket slides are captured and slightly compressed between the baseplate and the coverplate. Fasteners attach the coverplate to the baseplate, and the baseplate and coverplate each include apertures which align with the gasketed compartments of the gasket slides. Also disclosed are a system and a method for processing laboratory samples.
