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 (model ULF001C) from Yamato Scientific is a compact ultra-low laboratory freezer that holds samples between -40°C and -85°C. A microprocessor digital controller manages temperature, while audible and visual alarms, remote alarm contacts, battery alarm backup, and a 1/2-inch access port come standard. LabSupplies.com, authorized dealer, ships this unit.
Construction centers on a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior finished in powder-coated cool gray. Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and HCFC-free R-404A refrigerants. An air-cooled condenser using two heavy-duty fans needs no liquid coolant, which simplifies installation.
Electrical options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 25.25" × 25.75" × 40", and the freezer weighs 335 lbs. Built in the USA and UL Listed, this model holds six racks across 56 L of interior space.
Key Features
- Digital temperature control: dual display shows set point and chamber temperature, with a scan button for setting and a tamper-proof lockout.
- Battery-operated alarm system: audible and visual signals on mechanical or electrical failure, over- and under-temperature settings, silencing switch, and battery test switch.
- Cascade refrigeration: two hermetic compressors run CFC-free R-508B and CFC- and HCFC-free R-404A refrigerants.
- Air-cooled condenser: two heavy-duty fans dissipate heat with no liquid coolant required.
- Automatic power-failure recovery: a timer system restarts the unit after a power interruption.
- Remote alarm relay and access port: a relay supports remote alarm hook-up, and a 1/2-inch access port routes external probes.
How to Choose the Right Ultra-Low Freezer
Matching an ultra-low freezer to your lab means balancing sample volume, target temperature, and the power and floor space your facility can provide. Review these axes .
- Capacity: this chest model offers 56 L (2 cu.ft.) and holds six racks. Confirm the volume covers current sample inventory plus growth.
- Temperature range: a -40°C to -85°C range suits long-term storage of biological samples, enzymes, and reagents that demand deep-cold preservation.
- Control type: digital control with a dual display and tamper-proof lockout protects set points from accidental change.
- Voltage: verify your circuit matches an available option (115V, 208V, 230V at 60 Hz, or 220V at 50/60 Hz, single-phase).
- Footprint: exterior dimensions of 25.25" × 25.75" × 40" and a 335 lb weight determine placement and floor loading.
- Safety and monitoring: battery-backed alarms, a remote relay, and automatic power-failure recovery guard samples during outages.
