Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 13 cu.ft., Manual Defrost Overview
The Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 13 cu.ft., Manual Defrost (model ULF401UP) is an ultra-low laboratory freezer from Yamato Scientific, sold by LabSupplies.com as an authorized dealer. This upright unit holds 13 cu.ft. across five compartments and reaches -40°C to -85°C. A touch-screen controller manages set points, alarms, data logging, and remote access through USB, Ethernet, and FTP.
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in powder-coated cool gray. Cascade refrigeration uses two hermetic compressors charged with CFC-free R-508B and R-404A. Air-cooled condensing with two heavy-duty fans removes any need for liquid coolant. Four adjustable shelves create five compartments and support up to 15 racks.
Electrical options span 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 35" × 34.5" × 79.5", while shipping weight runs 850 lbs. Made in USA and UL Listed, the unit adds battery-backed alarms, dry-contact relays, and an automatic power-failure recovery timer.
Key Features

- Cascade refrigeration: two hermetic compressors and air-cooled condensing with two heavy-duty fans, using CFC-free R-508B and R-404A.
- Data acquisition and remote access: data logging downloadable via USB or FTP, plus VNC remote access from PC or smart devices.
How to Choose the Right Ultra-Low Freezer
Matching an ultra-low freezer to your lab depends on sample volume, target temperature, site power, and the monitoring your protocols require. Weigh these axes.
- Voltage and site power: verify your outlet matches the 115V, 208V, or 230V 60 Hz option before delivery to avoid install delays.
- Footprint: exterior dimensions of 35" × 34.5" × 79.5" and 850 lbs require a planned floor location with clearance for the air-cooled condenser.
