Undercounter Ultra Low Freezers -40°C To -85°C, 2 cu.ft., Manual Defrost Overview
The Undercounter Ultra Low Freezers -40°C To -85°C, 2 cu.ft., Manual Defrost (Yamato Scientific model ULF101UN) holds a 2 cu.ft. interior across a -40°C to -85°C range. This upright laboratory freezer fits beneath standard bench height, freeing floor space in crowded labs. Each unit ships from LabSupplies.com, an authorized Yamato Scientific dealer.
Stainless steel lines the interior cabinet, while electrogalvanized steel forms the exterior shell. CFC-free polyurethane insulation surrounds a cold-wall evaporator for stable low-temperature holding. A single solid locking door secures samples, and four leveling legs steady the cabinet on uneven floors.
Power runs on 115V, 60 Hz single-phase service through a NEMA 5-15P plug. Exterior dimensions measure 23 × 27 × 32 inches, and the unit weighs 240 lbs. Manufactured in the USA, the freezer carries ETL and UL listings. Plan for 4 inches of clearance on the sides and back.

How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer means matching storage demand, temperature target, and site power to your workflow. Weigh these axes against your sample inventory and lab layout before purchase.
- Capacity: a 2 cu.ft. (54 L) interior suits small sample libraries or satellite storage; confirm your tube, vial, or rack volume fits the 14 × 18 × 12.5 inch interior.
- Temperature range: a -40°C to -85°C span covers most long-term biological and reagent storage; verify your protocol's required setpoint sits inside this window.
- Control type: digital control with data logging documents temperature history for QC and audit needs.
- Voltage and power: 115V, 60 Hz single-phase service on a NEMA 5-15P plug fits standard North American lab circuits.
- Footprint: an undercounter profile preserves floor space; allow 4 inches of clearance on the sides and back.
- Safety and alarms: audible, visual, and remote alarms with battery back-up protect samples during failures or power loss.
