Chest Style Ultra Low Freezers -40°C To -85°C, 17 cu.ft., Manual Defrost Overview
The Chest Style Ultra Low Freezers -40°C To -85°C, 17 cu.ft., Manual Defrost (model ULF601C) is a laboratory ultra-low freezer from Yamato Scientific, offered by LabSupplies.com as an authorized dealer. This chest-format unit delivers 480 L (17 cu.ft.) of storage across a -40°C to -85°C range, with manual defrost and capacity for 36 racks of long-term sample preservation.
A cascade refrigeration system pairs two hermetic compressors with CFC-free R-508B and CFC- and HCFC-free R-404A refrigerants. Air-cooled condensing uses two heavy-duty fans and requires no liquid coolant. Chamber construction is 14-gauge zinc-coated galvanized steel; the exterior is 16-gauge steel powder coated in cool gray for durable, wipe-down service.
Power options cover 115V, 208V, and 230V at 60 Hz single-phase, plus 220V at 50/60 Hz single-phase. Exterior footprint measures 81.25" × 33.5" × 48.5", and the unit ships at 975 lbs from USA inventory. Made in USA and UL Listed, ULF601C arrives ready for demanding cold-storage workflows.
Key Features
- Digital control with dual display: shows set point and chamber temperature, with a scan button for temperature setting and a tamper-proof lockout.
- Battery-backed alarm system: audible and visual signals on mechanical or electrical failure, over- and under-temperature settings, alarm silencing switch, and battery test switch.
- Remote alarm capability: a built-in relay supports remote alarm hook-up for centralized facility monitoring.
- Automatic power-failure recovery: a timer system restarts the unit after a power interruption.
- Cascade refrigeration: two hermetic compressors with CFC-free R-508B and CFC- and HCFC-free R-404A reach the -85°C low.
- Robust build: 14-gauge galvanized steel chamber and 16-gauge powder-coated steel exterior, holding up to 36 racks.
How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer comes down to matching storage volume, temperature class, and site power to your sample protocol. Use these axes to confirm the unit fits both your samples and your facility.
- Capacity: 480 L (17 cu.ft.) and 36-rack support determine how many vials, plates, or bags you can store; size to your current inventory plus growth.
- Temperature range: a -40°C to -85°C span suits long-term preservation of cells, tissues, and reagents that demand sub-arctic storage.
- Control type: digital dual-display control with tamper-proof lockout protects set points from accidental changes in shared labs.
- Voltage: verify your circuit against the 115V, 208V, 230V, or 220V options before installation to avoid retrofitting power.
- Footprint and format: the chest design and 81.25" × 33.5" × 48.5" exterior favor top-access loading where floor space allows.
- Safety and monitoring: battery-backed alarms, remote contacts, and power-failure recovery matter where sample loss carries high cost.
