Abstract: The present invention relates to equipment for the automatic staining of biological samples, comprising: a staining unit able to house one or a plurality of staining trays organised in a matrix and able to house a slide-holder basket, said staining unit further comprising drive means of the slide-holder baskets; and an automatic system for maintaining and replacing the reagents, characterised by the fact that said drive means of said baskets comprise means for maintaining and replacing the reagent/stain inside a tray.

Abstract: An automatic tissue processor for processing tissue samples for histological analysis. The tissue processor in one configuration includes a retort chamber, a wax storage chamber holding multiple wax containers, a reagent storage chamber holding multiple reagent containers, and a fluid transporting system including a rotary valve operated by a Maltese Cross gear, for selectively connecting the retort chamber with a particular wax or reagent container to supply wax or reagents to the retort chamber. Differential heating of the wax chamber is accommodated by multiple heating elements, with indirect heating of the rotary valve and the fluid transporting system. A computerized central control system for automatic monitoring and control of such tissue processor is advantageously arranged to execute a reagent management program, which enables the central control system to automatically manage reagent usage and replacement.
