A -40°C upright freezer is a type of freezer designed to reach and maintain temperatures as low as -40 degrees Celsius. Upright freezers are characterized by their vertical orientation, similar to a standard refrigerator. Upright freezers have a vertical layout with shelves and compartments, providing easy access to stored items without the need to bend or reach deep into the freezer.  Commonly used in scientific laboratories for the storage of biological samples, reagents, and other temperature-sensitive materials.
