Abstract: A sanitation tray system for medical, laboratory, and industrial equipment. This system is modular, stackable, and user customizable. It may be assembled in any number of horizontal or vertical configurations depending on the user's needs and is capable of permitting instruments of varying heights, lengths and widths to be sanitized simultaneously. It is easily assemblable and disassemblable and includes a rack, corners, sides, and dowels. It is lightweight, easy to manufacture, easy to ship, and economical. It is designed to use the least amount of surface area to allow for maximum permeation of sterilants and minimizes the opportunity for pooling of sterilants or retention of particulate matter while decreasing drying time.
