Chest Style Ultra Low Freezers -40°C To -85°C, 3 cu.ft., Manual Defrost Overview
The Chest Style Ultra Low Freezers -40°C To -85°C, 3 cu.ft., Manual Defrost (model ULF101C) from Yamato Scientific is a laboratory ultra-low freezer delivering a -40°C to -85°C range across 83 L of chest-style storage. LabSupplies.com, an authorized dealer, supplies the genuine unit equipped with a microprocessor digital controller, audible and visual alarms, remote alarm contacts, battery alarm backup, and a 1/2-inch access port.
Construction pairs a 14-gauge zinc-coated galvanized steel chamber with a 16-gauge steel exterior in power-coated cool gray. A cascade refrigeration system runs two hermetic compressors charged with CFC- and HCFC-free R-508B and R-404A refrigerants. Air-cooled condensing uses two heavy-duty fans, so no liquid coolant is required.
Power options span 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior dimensions measure 34.5 × 25.25 × 48 inches, with a shipping weight near 500 lbs. Manufactured in the USA and UL Listed, the freezer holds 8 racks within a 24 × 12 × 18-inch interior.
Key Features
- Digital temperature control: dual display shows set point and chamber temperature, with a scan button for setting and a tamper-proof lockout.
- Cascade refrigeration: two hermetic compressors paired with CFC-free R-508B and R-404A for reliable pull-down across the -40°C to -85°C range.
- Battery alarm system: audible and visual signal on mechanical or electrical failure, plus over- and under-temperature settings, silencing switch, and battery test switch.
- Remote alarm relay: built-in relay enables hook-up to a central building or facility monitoring system.
- Automatic power failure recovery: timer system restarts the unit after a power interruption without manual intervention.
- Air-cooled condenser: two heavy-duty fans dissipate heat, eliminating any liquid coolant requirement; a 1/2-inch access port supports sensor or probe routing.
How to Choose the Right Ultra-Low Freezer
Matching an ultra-low freezer to your sample inventory and lab infrastructure prevents both wasted capacity and overloaded circuits. Weigh these axes before specifying a unit.
- Capacity: rate storage against your sample volume. This chest model offers 83 L (3 cu.ft.) and accepts 8 racks.
- Temperature range: confirm the unit reaches your protocol's target; this freezer operates from -40°C down to -85°C.
- Control type: digital control with a dual display and tamper-proof lockout supports validated, auditable storage versus simple analog dials.
- Voltage: verify your site power; options cover 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, all single-phase.
- Footprint: chest-style loading suits floor-space planning where vertical clearance is limited; exterior dimensions are 34.5 × 25.25 × 48 inches.
- Safety and monitoring: battery-backed alarms, over/under-temperature limits, and a remote relay protect samples during faults and power loss.
