Upright Ultra Freezers are made to store samples at ultra-low temperatures for the laboratory market. They have nominal range from 380 to 570 litres and are available in basic and advanced versions. According to the manufacturer, the CCS-System (conductive cooling on shelves) ensures maximum freezing performance to the product and a minimum loss to the surroundings. The internal volume on the four shelves, which are separated by insulated inner doors, can be used 100 percent, eliminating any expensive dead air space. All models have a maximum width of 800 mm.
