These large capacity, rugged polypropylene trays have multiple uses. The substantial depth and 8.5 liter (9 quart) volume of both can be used to hold a large quantity of samples on ice or as a water bath. The trays are steam autoclavable at 121°C (250°F) and are ideal for holding instruments while autoclaving. The deep trays are useful in a sink when cleaning glassware to reduce chance of damage or for transporting labware. Inside corners are rounded and smooth for easy cleaning. The top rim adds rigidity and provides handholds for transport.
