This versatile and rugged tray with lid is ideal for safely storing small items or holding instruments while autoclaving. It stacks with identical trays and lids to maximize cupboard and shelf storage capacity. The shallow depth is useful for holding small vials or bottles on ice or as a water bath. Inside corners of the tray are rounded and smooth for easy cleaning. Both tray and lid are molded polypropylene and steam autoclavable at 121°C (250°F).
