Platinum Upright Style Ultra Low Freezers -40°C To -80°C, 30 cu.ft., Manual Defrost Overview
The Platinum Upright Style Ultra Low Freezers -40°C To -80°C, 30 cu.ft., Manual Defrost (model ULF901UP) is an upright laboratory ultra-low freezer from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. Each unit delivers 30 cu.ft. of sample storage and holds a -40°C to -80°C operating range with manual defrost.
Chamber walls use 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel powder-coated cool gray. A cascade refrigeration system 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 to reach ultra-low temperatures.
Power options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 60.5" × 37" × 79.5", and the freezer ships at 1325 lbs. Made in the USA, the unit carries UL Listed certification.

- Power-failure recovery: an automatic timer restarts the unit once power returns, and a 1/2" access port ships with plugs.
