Platinum Upright Style Low Temperature Freezers 0°C To -40°C, 28 cu.ft., Manual Defrost Overview
The Platinum Upright Style Low Temperature Freezers 0°C To -40°C, 28 cu.ft., Manual Defrost (model LTF801UP) is a laboratory freezer from Yamato Scientific, supplied through LabSupplies.com as an authorized dealer. This upright unit holds 28 cu.ft. (792 L) and maintains chamber temperatures across a 0°C to -40°C range. A touch-screen digital controller manages set point, alarms, and data logging from a single interface.
Chamber walls use 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel finished in powder-coated cool gray. Four adjustable shelves create five compartments and accept up to 30 racks. Refrigeration runs on a single-stage system with one hermetic compressor and CFC- and HCFC-free refrigerant. An air-cooled condenser removes the need for liquid coolant.
Electrical configurations include 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. Exterior dimensions measure 54" × 37" × 79.5", and the freezer ships at 1,125 lbs. Manufactured in the USA and UL Listed, every unit undergoes seven days of testing before it leaves the factory.

How to Choose the Right Low-Temp Freezer
Selecting a low-temperature freezer comes down to matching storage volume, temperature class, and site power to your sample protection requirements. Use the criteria below to confirm the unit fits your workflow before purchase.
- Capacity: a 28 cu.ft. (792 L) interior with 30-rack capacity suits high-throughput sample archives; size to your current and projected inventory.
- Temperature range: the 0°C to -40°C span fits enzymes, reagents, and many biological samples that do not require ultra-low storage.
- Control type: a touch-screen controller with data logging and remote alerts supports labs that need audit-ready temperature records.
- Voltage and power: confirm your circuit matches an available configuration (115V, 208V, 230V at 60 Hz, or 220V at 50/60 Hz, single-phase).
- Footprint: verify the 54" × 37" × 79.5" exterior and 1,125 lb weight clear your doorways, floor rating, and ventilation clearances.
- Safety and monitoring: battery back-up, dry contacts, and audible/visual alarms protect samples during mechanical or power failures.
