Platinum Upright Style Ultra Low Freezers -40°C To -80°C, 28 cu.ft., Manual Defrost Overview
The Platinum Upright Style Ultra Low Freezers -40°C To -80°C, 28 cu.ft., Manual Defrost (model ULF801UP) is an upright ultra-low laboratory freezer from Yamato Scientific, sold by LabSupplies.com as an authorized dealer. Holding 792 L (28 cu.ft.) and reaching -40°C to -80°C, it stores up to 30 racks across four adjustable shelves in five compartments.
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in powder-coated cool gray. A cascade refrigeration system using two hermetic compressors and CFC-free R-508B and R-404A refrigerants drives pull-down. Air-cooled condensing with two heavy-duty fans removes heat without liquid coolant. The 1/2-inch side access port with plugs supports probes and external monitoring.
Power options cover 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. Exterior dimensions measure 54" × 37" × 79.5" (137 × 93 × 201 cm), and the unit ships at 1,125 lbs. Built in the USA and UL Listed, it carries a touch-screen controller with data logging, alarms, and remote VNC access.

How to Choose the Right Ultra-Low Freezer
Matching an ultra-low freezer to your lab means weighing storage volume against bench power, footprint, and sample-protection features. Use the criteria below to confirm the unit fits both your workflow and your facility.
- Capacity: 28 cu.ft. (792 L) and 30-rack support determine how many samples and rack systems you can store without a second unit.
- Temperature range: a -40°C to -80°C span suits long-term storage of biologics, enzymes, and similar temperature-sensitive material.
- Control type: a touch-screen controller with data logging and remote alerts matters for labs needing audit trails and off-site monitoring.
- Voltage: confirm your circuit matches the 115V, 208V, or 230V (60 Hz) or 220V (50/60 Hz) single-phase options before installation.
- Footprint: verify the 54" × 37" × 79.5" exterior and 1,125 lb weight clear doorways and floor-load limits.
- Safety and back-up: battery alarm, dry contacts, and optional CO₂/LN₂ back-up protect samples during outages.
