Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 3 cu.ft., Manual Defrost Overview
The Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 3 cu.ft., Manual Defrost (model ULF101CP) is a cascade-refrigerated laboratory freezer from Yamato Scientific, sold by LabSupplies.com, authorized dealer. Engineered for −40°C to −85°C storage across 83 L (3 cu.ft.) of chamber space, this chest unit holds up to 8 racks of long-term sample inventory.
Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants, reaching ultra-low setpoints without liquid coolant. An air-cooled condenser uses two heavy-duty fans for heat rejection. The chamber is 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel powder coated cool gray. A 1/2-inch access port sits on the left-hand side with plugs.
Power options span 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz. Exterior dimensions measure 34.5 × 25.25 × 48 inches, with a shipping weight near 500 lbs. Built in the USA and UL Listed, the freezer arrives ready for installation. Automatic power-failure recovery restarts the unit after outages.

How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer means matching storage volume, target temperature, and site infrastructure to your sample workflow. Weigh these axes before specifying a unit.
- Capacity: Match chamber volume and rack count to your sample inventory; this 3 cu.ft. chest holds up to 8 racks.
- Temperature range: Confirm the freezer reaches your required setpoint; −40°C to −85°C covers most long-term biological storage.
- Control and monitoring: Decide whether touch-screen control, data logging, and remote alarms are needed for compliance and traceability.
- Voltage: Verify available site power against the unit's 115V, 208V, and 230V options to avoid installation delays.
- Footprint: Check exterior dimensions and weight against your floor space and load limits before delivery.
- Safety backup: Consider CO₂ or LN₂ backup and battery-backed alarms where sample-loss risk is high.
