Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 22 cu.ft., Manual Defrost Overview
The Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 22 cu.ft., Manual Defrost (model ULF601UP) is an upright ultra-low laboratory freezer from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. Capacity reaches 22 cu.ft. (626 L) across a -40°C to -85°C range. Sample protection comes from a touch-screen controller, audible and visual alarms, and battery alarm back-up.
Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants, cooled by an air-cooled condenser and two heavy-duty fans that require no liquid coolant. The chamber uses 14-gauge zinc-coated galvanized steel, while a 16-gauge steel exterior carries a powder-coated cool-gray finish. Four adjustable shelves create five compartments and hold up to 25 racks.
