Upright Style Low Temperature Freezers 0°C To -40°C, 22 cu.ft., Manual Defrost Overview
The Upright Style Low Temperature Freezers 0°C To -40°C, 22 cu.ft., Manual Defrost (model LTF601U) is a laboratory freezer engineered for reliable cold storage across a 0°C to −40°C range. Built by Yamato Scientific and stocked by LabSupplies.com as an authorized dealer, this upright unit delivers 22 cu.ft. (626 L) of manual-defrost capacity for sample and reagent storage.
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 accommodate up to 25 racks across the 626 L interior. A single-stage refrigeration system with one hermetic compressor and an air-cooled condenser runs on CFC- and HCFC-free refrigerant, requiring no liquid coolant.
Power options cover 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. Exterior dimensions measure 43" × 37" × 79.5", and the unit ships at 975 lbs. Manufactured in the USA and UL Listed, each freezer undergoes a 7-day full performance test before it leaves the factory.
Key Features
- Dual-display digital control: a microprocessor controller drives two displays — one shows the set temperature, the other the actual chamber temperature.
- Battery-backed alarm system: audible and visual signals trigger on mechanical or electrical failure, with over- and under-temperature settings, an alarm silencing switch, and a battery test switch.
- Remote monitoring ready: a relay is provided for remote alarm hook-up, and a 1/2" access port supports external probes or recorders.
- CFC- and HCFC-free refrigeration: a single-stage system with one hermetic compressor and an air-cooled condenser needs no liquid coolant.
- Configurable storage: four adjustable shelves form five compartments and hold up to 25 racks within the 626 L chamber.
- Factory-tested performance: every freezer runs a 7-day test and holds its low setpoint in warm ambient conditions up to +30°C.
How to Choose the Right Low-Temp Freezer
Selecting a low-temperature upright freezer comes down to matching capacity, temperature performance, and site power to your storage program. Weigh these criteria against your sample volume and lab infrastructure before specifying a unit.
- Capacity: interior volume (here 22 cu.ft. / 626 L) and rack count determine how many samples you can store; size to current load plus future growth.
- Temperature range: confirm the unit reaches your required setpoint — this model holds 0°C to −40°C, suiting samples that do not need ultra-low −80°C storage.
- Control type: a digital dual-display controller lets technicians verify set and actual chamber temperature at a glance, improving documentation and QC.
- Voltage and power: match the freezer to available circuits; this model supports 115V, 208V, 230V, and 220V single-phase configurations.
- Footprint and weight: verify exterior dimensions (43" × 37" × 79.5") and floor loading (975 lbs) against your lab layout and access routes.
- Safety and alarms: battery-backed audible/visual alarms and remote relay contacts protect samples during power or mechanical failures.
