Undercounter Ultra Low Freezers -40°C To -85°C, 3 cu.ft., Manual Defrost Overview
The Undercounter Ultra Low Freezers -40°C To -85°C, 3 cu.ft., Manual Defrost (model ULF201UN) is a Yamato Scientific ultra-low laboratory freezer holding 94 L across a -40°C to -85°C range. LabSupplies.com supplies this unit as an authorized dealer. A digital controller with data logging, audible and visual alarms, remote alarm contacts, and battery back-up ships standard.
Stainless steel lines the interior cabinet, while electrogalvanized steel forms the exterior shell. CFC-free polyurethane insulation and a cold wall evaporator support stable cold retention. A single solid locking door secures samples, and four leveling legs steady the cabinet on uneven floors.
Power draws from a standard 115V, 60 Hz, single-phase circuit through a NEMA 5-15P plug. Exterior dimensions measure 37.5" × 28.5" × 32", and the freezer weighs 295 lbs. Built in the USA, the unit carries ETL and UL listings. Maintain 4" clearance on the sides and back.

How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer starts with matching the unit to your sample volume and the lowest temperature your protocols demand. Weigh footprint, power supply, and monitoring needs against your lab's existing infrastructure before purchasing.
- Capacity: confirm 3 cu.ft. (94 L) suits your sample throughput and rack layout.
- Temperature range: verify the -40°C to -85°C span covers your coldest storage protocols.
- Control type: digital control with data logging supports temperature audit trails and compliance records.
- Voltage: the 115V, 60 Hz, single-phase requirement must match an available NEMA 5-15 circuit.
- Footprint: the undercounter exterior of 37.5" × 28.5" × 32" needs 4" clearance on the sides and back.
- Safety: battery-backed audible and visual alarms protect samples during power or mechanical failure.
