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.

Frequently Asked Questions
What temperature range does the Yamato ULF301CP reach?
The ULF301CP operates from -40°C to -85°C. Cascade refrigeration with two hermetic compressors and CFC-free R-508B and R-404A refrigerants drives the pull-down, supporting long-term deep-cold sample storage.
How much storage capacity does this freezer provide?
Interior capacity is 255 L (9 cu.ft.) with room for up to 16 racks. Interior dimensions measure 46" × 16" × 20", and exterior dimensions are 57.5" × 29" × 46.5".
What voltage and power does the ULF301CP require?
Electrical requirements cover 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. Confirm your facility power before installation to match the correct configuration.
What materials are used in the freezer construction?
The chamber is built from 14-gauge zinc-coated galvanized steel. Exterior panels use 16-gauge steel finished in powder-coated cool gray for durability in lab environments.
What defrost type and refrigeration system does it use?
Defrost is manual, and refrigeration is a cascade type with two hermetic compressors. An air-cooled condenser with two heavy-duty fans removes heat, so no liquid coolant is needed.
How does the ULF301CP protect samples during a power failure?
A battery-operated alarm signals mechanical or electrical failures both audibly and visually. An automatic timer system restarts the unit after power returns, and dry contacts allow remote alarm hook-up.
