Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 12 cu.ft., Manual Defrost Overview
The Platinum Chest Style Ultra Low Freezers -40°C To -85°C, 12 cu.ft., Manual Defrost (model ULF401CP) is a cascade-refrigeration laboratory freezer from Yamato Scientific, holding 340 liters across a -40°C to -85°C range. LabSupplies.com supplies this chest unit as an authorized Yamato Scientific dealer. A touch-screen controller, data logging, and battery-backed alarms ship standard.
Two hermetic compressors drive the cascade refrigeration system, paired with an air-cooled condenser and two heavy-duty fans that require no liquid coolant. The chamber uses 14-gauge zinc-coated galvanized steel, while a 16-gauge steel exterior carries a power-coated cool gray finish. CFC-free R-508B and CFC- and HCFC-free R-404A serve as the refrigerants.
Key Features
- Touch-screen control system: displays set point and chamber temperature, with Hi/Low alarm plus email and SMS notification.
- Data acquisition: downloadable logging via USB or FTP, viewable temperature graph, multi-level security, and VNC remote access from a PC or smart device.
- Battery-backed alarm: audible and visual signal on mechanical or electrical failure, over- and under-temperature settings, silencing switch, battery test switch, and a relay for remote alarm hook-up.
- Cascade refrigeration: two hermetic compressors with an air-cooled, twin-fan condenser reach the -40°C to -85°C range without liquid coolant.
- Power failure recovery: an automatic timer system restarts the unit after a power interruption.
How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer comes down to matching storage volume, achievable temperature, and site infrastructure to your sample protocols. Use the criteria below to confirm the ULF401CP fits your lab before ordering.
- Capacity: 12 cu.ft. (340 L) and 27-rack capacity define how many vials, plates, or bags you can archive; confirm projected sample growth against this footprint.
- Voltage and power: match your circuit to the 115V, 208V, or 230V 60 Hz single-phase options (or 220V 50/60 Hz) before installation.
- Footprint and format: a chest design needs 65.5 × 32 × 47.5 inches of floor clearance and supports top-loading access at 825 lbs.
