Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 9 cu.ft., Manual Defrost Overview
The Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 9 cu.ft., Manual Defrost (model ULF301CP) is a cascade-refrigeration ultra-low laboratory freezer from Yamato Scientific, holding 255 L (9 cu.ft.) across a -40°C to -85°C range. LabSupplies.com supplies this unit as an authorized dealer. A touch-screen controller manages set point, 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. Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants. Air-cooled condensing through two heavy-duty fans removes the need for liquid coolant.
Electrical options span 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. Exterior dimensions measure 57.5" × 29" × 46.5", and shipping weight reaches 675 lbs. Built in the USA, this freezer carries UL Listed certification.
Key Features
- Touch-screen control system: displays set point and chamber temperature, with viewable temperature graph, data logging, multi-level security, and VNC remote access via PC or smart devices.
- Cascade refrigeration: two hermetic compressors run CFC- and HCFC-free R-508B and R-404A refrigerants for stable pull-down to -85°C.
