Chest Style Low Temperature Freezers 0°C To -40°C, 12 cu.ft., Manual Defrost Overview
The Chest Style Low Temperature Freezers 0°C To -40°C, 12 cu.ft., Manual Defrost (model LTF401C) is a laboratory chest freezer from Yamato Scientific, supplied through LabSupplies.com, authorized dealer. Holding 340 L across a 0°C to -40°C range, this unit ships standard with a microprocessor digital controller, audible and visual alarms, remote alarm contacts, battery alarm backup, and a 1/2-inch access port.
Construction centers on a 14-gauge zinc-coated galvanized steel chamber paired with a 16-gauge steel exterior finished in powder-coated cool gray. A single-stage refrigeration system uses one hermetic compressor running a CFC- and HCFC-free refrigerant. Air-cooled condensing removes any need for liquid coolant. Dual digital displays show the setpoint and the actual chamber temperature side by side.
Electrical options cover 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase. Exterior dimensions measure 65.5 × 32 × 47.5 inches, and the freezer weighs 775 lbs. Made in USA, the LTF401C is UL Listed and tested for 7 days under demanding conditions before shipment.
Key Features
- Digital dual-display control: a microprocessor controller drives two displays, one showing the set temperature and the other the actual chamber temperature.
- Battery-backed alarm system: audible and visual alarms trigger on mechanical or electrical failure, with over- and under-temperature settings, an alarm silencing switch, a battery test switch, and a relay for remote hook-up.
- CFC- and HCFC-free refrigeration: a single-stage system with one hermetic compressor and an air-cooled condenser, requiring no liquid coolant.
- 340 L storage: 12 cu.ft. of interior capacity holding up to 27 racks.
- 1/2-inch access port: dedicated port for probes, sensors, or monitoring leads.
- 7-day factory testing: every freezer runs a full 7-day validation, with a low setpoint guaranteed in warm (+30°C) ambient environments.
How to Choose the Right Low-Temp Freezer
Matching a chest freezer to your samples means balancing storage volume, temperature performance, site power, and protection against failure. Use these axes to size the right unit for your lab.
- Capacity: 340 L (12 cu.ft.) and 27-rack capacity determine how many samples or racks you can store, so confirm your throughput before specifying.
- Temperature range: a 0°C to -40°C span suits enzymes, reagents, and many biological samples that do not require ultra-low -80°C storage.
- Control type: dual digital displays let technicians verify the actual chamber temperature against the setpoint at a glance.
- Voltage: options span 115V, 208V, 230V, and 220V, single-phase, so match the unit to your available circuit.
- Footprint: chest geometry measures 65.5 × 32 × 47.5 inches and weighs 775 lbs, so verify floor space and load.
- Safety: battery-backed audible and visual alarms plus a remote relay protect samples during power or mechanical faults.
