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 compact laboratory ultra-low freezer holding 83 L (3 cu.ft.) across an adjustable -40°C to -85°C range. LabSupplies.com, authorized dealer, supplies this chest-format unit for long-term storage of biological samples, reagents, and cell lines.
A cascade refrigeration system pairs two hermetic compressors with CFC- and HCFC-free R-508B and R-404A refrigerants to reach -85°C. Air-cooled twin heavy-duty fans handle condensing, so no liquid coolant is required. The chamber uses 14-gauge zinc-coated galvanized steel; an exterior of 16-gauge steel carries a power-coated cool gray finish.
Digital control with a dual display shows set point and chamber temperature, with a tamper-proof lockout. Standard battery-operated alarms, remote alarm relay, and an automatic power-failure recovery timer protect stored samples. Built in the USA and UL Listed, the unit weighs 500 lbs, measures 34.5" × 25.25" × 48", and runs on 115V, 208V, 230V, or 220V power.

How to Choose the Right Ultra-Low Freezer
Ultra-low freezer selection hinges on storage volume, the temperature your samples demand, and the power available at the install site. Match these axes to your protocol before specifying a unit.
- Capacity: the ULF101C holds 83 L (3 cu.ft.) and up to 8 racks; confirm your sample inventory and growth fit the interior footprint.
- Temperature range: an adjustable -40°C to -85°C span covers most enzymes, sera, and cell-line storage; verify your coldest required set point.
- Control type: digital dual-display control with tamper-proof lockout prevents accidental set-point changes in shared lab spaces.
- Voltage: available for 115V, 208V, 230V, and 220V circuits — match the unit to your facility's outlet and breaker rating.
- Footprint: exterior dimensions of 34.5" × 25.25" × 48" and 500 lb weight determine bench clearance and floor loading.
- Sample protection: battery-backed alarms, remote alarm relay, and automatic power-failure recovery safeguard contents during outages.
