Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 14 cu.ft., Manual Defrost Overview
The Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 14 cu.ft., Manual Defrost (model ULF501CP) is a cascade-refrigerated laboratory freezer holding 14 cu.ft. across a -40°C to -85°C operating range. Yamato Scientific engineers this chest-style unit for long-term storage of biological samples, reagents, and tissue. LabSupplies.com supplies it as an authorized dealer.
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in powder-coated cool gray. Two hermetic compressors drive the cascade refrigeration system, using CFC-free R-508B and R-404A refrigerants. An air-cooled condenser with two heavy-duty fans removes heat, so no liquid coolant is required. A 1/2" access port sits on the left-hand side with plugs.
Electrical options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 72.5" × 33" × 47.5", and shipping weight is 900 lbs. Made in the USA, the unit carries UL Listed certification. Automatic power-failure recovery restarts the freezer after an outage.

How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer comes down to matching storage volume, temperature class, control depth, and site power to your sample protocols. Use the criteria below to confirm the unit fits both the workflow and the facility.
- Capacity: verify usable interior volume and rack count against your sample inventory; this model holds 14 cu.ft. (400 L) and accepts 30 racks.
- Temperature range: confirm the protocol's required low; a -40°C to -85°C range supports long-term storage of cells, tissue, and sensitive reagents.
- Control and monitoring: decide whether you need touch-screen set point display, data logging, and remote alarm notifications for audit trails and uptime.
- Voltage and site power: match the available circuit, since this unit offers 115V, 208V, 230V at 60 Hz and 220V at 50/60 Hz single-phase.
- Footprint and weight: measure your space and floor rating against the 72.5" × 33" × 47.5" exterior and 900 lb shipping weight.
- Safety and recovery: evaluate battery back-up, audible/visual alarms, and automatic power-failure recovery for sample protection.
