Chest Style Ultra Low Freezers -40°C To -85°C, 2 cu.ft., Manual Defrost Overview
The Chest Style Ultra Low Freezers -40°C To -85°C, 2 cu.ft., Manual Defrost (ULF-001C) from Yamato Scientific is a cascade-refrigeration laboratory freezer built for sample storage down to -85°C. This 2 cu.ft. chest-style unit holds up to 6 racks inside a 56 L chamber. LabSupplies.com supplies it as an authorized dealer.
Construction centers on a 14-gauge zinc-coated galvanized steel chamber paired with a 16-gauge steel exterior finished in powder-coated cool gray. Two hermetic compressors drive the cascade refrigeration system, while an air-cooled condenser with two heavy-duty fans removes heat without liquid coolant. CFC-free R-508B and HCFC-free R-404A refrigerants carry the thermal load.
Electrical options span 115V, 208V, and 230V at 60 Hz single-phase, plus a 220V 50/60 Hz configuration. Exterior dimensions measure 25.25" × 25.75" × 40", and the freezer ships at 335 lbs. Manufactured in the USA, this unit carries UL Listed certification.
Key Features
- Digital temperature control: microprocessor controller with a dual display showing set point and chamber temperature, a scan button for setting, and tamper-proof lockout.
- Cascade refrigeration: two hermetic compressors with an air-cooled, dual-fan condenser deliver sustained pull-down with no liquid coolant required.
- Battery-backed alarm system: audible and visual signals on mechanical or electrical failure, over- and under-temperature settings, silencing switch, and battery test switch.
- Remote alarm capability: a relay is provided for remote alarm hook-up, with remote alarm contacts standard.
- Power failure recovery: an automatic timer system restarts the unit after a power interruption.
- 1/2" access port: standard port supports probes and supplementary monitoring.
How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer comes down to matching storage demand, target temperature, and site infrastructure to the unit's design. Weigh these axes before committing.
- Capacity: the 2 cu.ft. / 56 L chamber holds up to 6 racks, suiting focused sample sets rather than high-throughput biorepositories.
- Temperature range: a -40°C to -85°C span covers most biological and reagent storage needs that demand sub-zero stability.
- Control type: a digital dual-display controller with tamper-proof lockout protects set points in shared lab spaces.
- Voltage and site power: confirm whether your facility provides 115V, 208V, 230V at 60 Hz, or 220V at 50/60 Hz before ordering.
- Footprint: verify the 25.25" × 25.75" × 40" exterior fits the bench or floor space allotted.
- Safety and continuity: battery-backed alarms, remote alarm relay, and automatic power-failure recovery guard samples against unattended failures.
