Upright Style Low Temperature Freezers 0°C To -40°C, 25 cu.ft., Manual Defrost Overview
The Upright Style Low Temperature Freezers 0°C To -40°C, 25 cu.ft., Manual Defrost (model LTF701U) is a laboratory freezer from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. This upright unit delivers 25 cu.ft. (710 L) of storage across a 0°C to -40°C range. Standard equipment includes a microprocessor digital controller, audible and visual alarms, remote alarm contacts, battery alarm back-up, and a 1/2" access port.
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in powder-coated cool gray. Four adjustable shelves create five compartments and hold up to 30 racks within interior dimensions of 34" × 25" × 51.25". Refrigeration uses a single-stage system with one hermetic compressor, an air-cooled condenser, and CFC- and HCFC-free refrigerant.
Electrical options span 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. Exterior dimensions measure 50" × 37" × 79.5" with a shipping weight of 1,125 lbs. Built in the USA and UL Listed, every freezer undergoes 7 days of testing and holds its setpoint in ambient environments up to +30°C.
Key Features
- Dual-display digital control: a microprocessor controller shows the set temperature on one display and the actual chamber temperature on the other.
- Battery-backed alarm system: audible and visual signals on mechanical or electrical failure, over- and under-temperature settings, an alarm-silencing switch, a battery-test switch, and a relay for remote hookup.
- CFC- and HCFC-free refrigeration: a single-stage system runs one hermetic compressor with an air-cooled condenser that needs no liquid coolant.
- Configurable storage: four adjustable shelves form five compartments and accept up to 30 racks across 25 cu.ft. (710 L).
- 7-day performance testing: each freezer is fully tested under demanding conditions and guaranteed to hold a constant low setpoint in warm +30°C ambient environments.
- Optional accessories: chart recorder, CO₂ and LN₂ back-up system, additional racks, and cold safety gloves.
How to Choose the Right Low-Temp Freezer
Specifying an upright low-temperature freezer comes down to matching storage volume, thermal range, and site power to your sample protocol. Weigh these axes .
- Capacity: the LTF701U holds 25 cu.ft. (710 L) and up to 30 racks — size to your current sample inventory plus growth.
- Temperature range: a 0°C to -40°C span suits long-term storage that does not require ultra-low -80°C conditions.
- Control type: a microprocessor digital controller with dual displays lets technicians verify set and actual temperatures at a glance.
- Voltage: confirm your circuit against the available 115V, 208V, 230V (60 Hz) or 220V (50/60 Hz) single-phase options.
- Footprint: exterior dimensions of 50" × 37" × 79.5" and a 1,125 lb weight must fit your floor plan and load path.
- Safety monitoring: battery-backed audible/visual alarms and a remote-alarm relay protect samples during power or mechanical failures.
