-86°C Ultra Low Temperature Freezer - Upright ULT Freezer - 338 to 838 L - Cascade Cooling

The Master Science -86°C ULT Freezer stores plasma, vaccines, reagents, strains, biological products and other samples between -40 and -86 °C. Two SECOP compressors in a cascade refrigeration system cool the cabinet quickly and hold the lowest setting steadily over long periods.

Four insulated inner doors divide the chamber into separate compartments, which cuts cold loss and frost when the door is opened. Five upright sizes cover 338 to 838 litres.
