Ultra-low temperature storage boxes designed to hold 1.2ml to 2.0ml cryogenic storage vials. An excellent and longlasting replacement to cardboard boxes, they are fully autoclavable and withstand temperatures from -196°C to +121°C. They are compatible with all standard 5.25 inch (133mm) freezer racks. Clear lids are hinged and have printed indexing for sample identification purposes. The hinged lid adds convenience (opens and closes with just one hand) and eliminates confusion caused by incorrect lid orientation.

The front of each box has a unique barcode for additional identification benefits. These barcodes are permanent and resist extreme temperatures and long-term wear.
