Lab trays & pans are invisible but vital instruments in every laboratory. Easily overlooked, almost every lab relies on some kind of tray or pan to transfer and store samples & substances.
Lab trays are manufactured in several configurations, including rectangular (or "utility") trays, those with dispensing nozzles for liquids, and flat variants that wouldn't look out of place in a hospital cafeteria. Also available are baskets, draining trays, and waste containers.
Material is a key concern for any lab container, and trays are no different. Trays are available in polyethylene (PE), polypropylene (PP), and high-density polyethylene (HDPE).
