Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 5 cu.ft., Manual Defrost Overview
The Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 5 cu.ft., Manual Defrost (model ULF201CP) is a cascade-refrigeration laboratory freezer from Yamato Scientific. Sold by LabSupplies.com as an authorized dealer, this chest-style unit holds 142 L (5 cu.ft.) and reaches set points from -40°C to -85°C. A touch-screen controller manages temperature, alarms, and data logging.
Chamber walls use 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel finished in powder-coated cool gray. Two hermetic compressors form a cascade refrigeration system charged with CFC-free R-508B and HCFC-free R-404A. Air-cooled condensing with two heavy-duty fans removes heat, so no liquid coolant is required. Manual defrost keeps the design straightforward.
Power options cover 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. Exterior dimensions measure 40.5" × 31" × 47", and the unit weighs 525 lbs. Built in the USA, this freezer is UL Listed. Interior space accepts up to 15 racks for high-density sample storage.

How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer comes down to matching sample volume, temperature target, and site infrastructure to the unit you specify. Use the criteria below to align the freezer with your lab's workflow.
- Capacity: a 5 cu.ft. (142 L) chamber holding up to 15 racks suits focused sample collections without consuming a full equipment bay.
- Temperature range: a -40°C to -85°C span covers most long-term storage of biologicals, enzymes, and reagents; confirm your protocol's required set point.
- Control type: a touch-screen controller with data logging and remote alarms simplifies compliance documentation and off-hours monitoring.
- Voltage: verify your facility power against the 115V, 208V, 230V (60 Hz) and 220V (50/60 Hz) single-phase options before installation.
- Footprint: chest-style cabinets like this 40.5" × 31" × 47" unit offer top-access storage where floor space allows a horizontal layout.
- Safety and backup: battery-backed alarms, dry-contact relays, and optional CO₂/LN₂ backup protect samples during failure events.
