Platinum Chest Style Low Temperature Freezers 0°C To -40°C, 27 cu.ft., Manual Defrost Overview
The Platinum Chest Style Low Temperature Freezers 0°C To -40°C, 27 cu.ft., Manual Defrost (model LTF901CP) from Yamato Scientific is a chest-format laboratory freezer holding 766 L across a 0°C to -40°C range. Standard equipment includes a touch-screen digital controller, audible and visual alarms, remote alarm contacts, USB and Ethernet ports, data acquisition, and battery alarm back-up. LabSupplies.com supplies this unit as an authorized dealer.
Chamber walls use 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel finished in powder-coated cool gray. A single-stage refrigeration system with one hermetic compressor and an air-cooled condenser removes the need for liquid coolant. Refrigerant is CFC- and HCFC-free. The 1/2-inch porthole on the left-hand cabinet side accepts probes and ships plugged.
Electrical configurations cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 98 × 36 × 43.5 inches, and shipping weight reaches 1,125 lbs. Built in the USA and UL Listed, every freezer undergoes 7 days of full testing under demanding conditions before shipment.

How to Choose the Right Low-Temp Freezer
Selecting a chest-style low-temperature freezer comes down to matching storage volume, thermal range, and site power to your sample protocols. Weigh these axes against your lab footprint and protection requirements before specifying a model.
- Capacity: the 766 L / 27 cu.ft. chamber and 48-rack support determine how many samples and racks you can store per unit.
- Temperature range: a 0°C to -40°C span suits specimens that do not require ultra-low -80°C storage, helping you avoid over-specifying.
- Control type: touch-screen control with data logging and remote access matters for labs needing audit trails and off-site monitoring.
- Voltage: confirm your circuit matches one of the 115V, 208V, 230V (60 Hz) or 220V (50/60 Hz) single-phase configurations.
- Footprint: verify the 98 × 36 × 43.5-inch exterior and 1,125 lb shipping weight fit your floor plan and access path.
- Safety: battery-backed alarms, remote contacts, and optional CO₂/LN₂ back-up protect samples during power or mechanical failures.
