Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 22 cu.ft., Manual Defrost Overview
The Platinum Upright Style Ultra Low Freezers -40°C To -85°C, 22 cu.ft., Manual Defrost (model ULF601UP) is an upright ultra-low laboratory freezer from Yamato Scientific, supplied by LabSupplies.com as an authorized dealer. Capacity reaches 22 cu.ft. (626 L) across a -40°C to -85°C range. Sample protection comes from a touch-screen controller, audible and visual alarms, and battery alarm back-up.
Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants, cooled by 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 powder-coated cool-gray finish. Four adjustable shelves create five compartments and hold up to 25 racks.
Connectivity includes a USB port, an ethernet port, and a 1/2-inch side access port with plugs for probes or sensors. Electrical options span 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, single-phase. Built in the USA and UL Listed, this freezer weighs 975 lbs and measures 43" × 37" × 79.5" externally.
Key Features

How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer means matching sample volume, storage temperature, and your facility's power and floor space. Use these axes to confirm the unit fits your protocol before purchase.
- Capacity: rack count and interior volume determine how many samples you can store; this model offers 626 L (22 cu.ft.) and holds up to 25 racks across five compartments.
- Temperature range: verify the freezer reaches your archival set point; this unit operates from -40°C to -85°C for long-term biological and reagent storage.
- Control and monitoring: touch-screen control with data logging, email/SMS alerts, and remote VNC access matters for labs that document chain-of-custody and need off-site oversight.
- Voltage: confirm your circuit supports the unit; options cover 115V, 208V, and 230V at 60 Hz, plus 220V at 50/60 Hz, single-phase.
- Footprint and weight: plan installation around the 43" × 37" × 79.5" exterior and 975 lb weight, including clearance for the air-cooled condenser fans.
- Safety and continuity: battery alarm back-up, automatic power-failure restart, and an optional CO₂ or LN₂ back-up system protect samples during outages.
