Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 22 cu.ft., Manual Defrost Overview
The Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 22 cu.ft., Manual Defrost (model ULF801CP) from Yamato Scientific is a cascade-cooled laboratory chest freezer holding 626 liters (22 cu.ft.) across a -40°C to -85°C range. A touch-screen digital controller manages set point, alarms, and data logging. LabSupplies.com supplies this unit as an authorized Yamato Scientific dealer.
Chamber walls use 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel finished in powder-coated cool gray. Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and HCFC-free R-404A refrigerants. Air-cooled condensing relies on two heavy-duty fans, so no liquid coolant is required.
Power options span 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. The cabinet measures 98 inches wide externally and weighs 1,075 pounds. Made in the USA, this freezer is UL Listed and supports up to 36 storage racks.
Key Features

How to Choose the Right Ultra-Low Freezer
Matching an ultra-low freezer to your lab means balancing sample volume, the temperature your protocol demands, and the power your facility can supply. Use these axes to qualify a unit before purchase.
- Capacity: rated storage of 626 L (22 cu.ft.) and up to 36 racks determines how many sample boxes or vials you can hold without a second unit.
- Voltage: confirm your circuit against the 115V/208V/230V at 60 Hz or 220V at 50/60 Hz single-phase options before installation.
- Footprint: chest-style cabinets need floor clearance for the 98-inch external width and lid access from above.
