A slide output module

A method of hydrating tissue samples disposed on slides, the method comprising the steps of:

• an automated treatment apparatus locating a slide in a void in a slide output module of the automated treatment apparatus following treatment by the automated treatment apparatus, wherein the void is formed in a slide output tray assembly of the slide output module comprising a slide output tray adjacent to a slide output cover;
• the automated treatment apparatus inputting fluid to the slide in the void via a fluid inlet in a first side of the slide output tray cover, wherein the fluid inlet is in communication with the void;
• and
• the void forming a hydration chamber with the slide in the void and a second side of the slide output tray cover to maintain hydration of the slide with the fluid for a designated time.
