The ULF-201UN is an undercounter mini-chest ultra-low freezer in Yamato's STANDARD ULF Series, packing 94 L (3 cu.ft.) of ultra-low storage rated to -40°C to -85°C / -76°F to -121°F into a bench-height footprint that slides beneath a standard lab counter. It uses a cold-wall evaporator with polyurethane CFC-free insulation, digital data logging, battery back-up, and a Hi/Low alarm with remote-alarm relay — a point-of-use ULT for clinics, satellite labs, and hospital rooms where floor space is at a premium.

Application Profile
Per the ULF brochure, ULF Series ultra-low freezers serve clinics, research, small laboratories, hospital rooms, and medical clinics. The undercounter 3 cu.ft. configuration is purpose-built for point-of-use, space-constrained storage where an upright or chest ULT will not fit: clinical and hospital-room sample holding at the bench where floor space is unavailable, satellite or decentralized biorepository nodes close to sample collection, and reagent and enzyme storage that needs true ultra-low temperatures at the workstation. It also suits small-lab and clinic archives where a full-size ULT is oversized for the sample load.
Design Architecture
Refrigeration. The undercounter model uses a cold-wall evaporator with polyurethane CFC-free insulation and manual defrost. The specific refrigerant charge is not stated in the undercounter section of the ULF brochure and should be confirmed with Yamato.
Temperature control & alarms. Digital temperature control with dual display shows set point and chamber temperature. Digital data logging is provided. A battery-operated alarm emits audible and visual signals on mechanical or electrical failure, with over/under-temperature settings, an alarm-silence switch, and a relay for remote-alarm hook-up.
Construction. Single solid, locking door; four leveling legs; 4" clearance required on sides and back. ETL listed; 115V / 60Hz / NEMA 5-15P supply plug.
Interior dimensions: 14" x 19.25" x 20.75" (36 x 49 x 53 cm). Confirm rack/insert options with Yamato.

Ordering & Configuration
The ULF-201UN ships as a complete, factory-charged ultra-low freezer with digital control, dual display, and the battery-backed alarm system described above.
As a Type-A, quote-based capital item, the unit is rated -40°C to -85°C / -76°F to -121°F; confirm your temperature target against that spec, along with rack/insert configuration, which is not itemized in the undercounter brochure section and must be confirmed with Yamato. Confirm the following on quote:
- Voltage & plug — 115V, 60Hz, 1 phase (NEMA 5-15P, ETL listed)
- Freight — LTL freight (capital cold-storage equipment); confirm dock/liftgate and placement access
- Lead time and warranty terms
Request a quote to configure voltage, freight, and accessories for the ULF-201UN. Because this is a Type-A capital item, checkout is quote-based — our team confirms specification and total delivered cost before order.
Author note (spec gap): The undercounter mini-chest section of the STANDARD ULF brochure itemizes capacity, temperature range, and internal/external dimensions for this SKU, but does not state the refrigerant charge or rack capacity. Those two fields are flagged for confirmation with Yamato and were not fabricated.
