Platinum Chest Style Ultra Low Freezers -40°C To -80°C, 21Cu.Ft., Manual Defrost Overview
The Platinum Chest Style Ultra Low Freezers -40°C To -80°C, 21Cu.Ft., Manual Defrost (model ULF701CP) is a 21 cu.ft. chest-style ultra-low laboratory freezer reaching -40°C to -80°C. A touch-screen digital controller displays set point and chamber temperature. Audible and visual alarms, remote alarm contacts, USB and Ethernet ports, data acquisition, battery alarm back-up, and a 1/2" access port all come standard from Yamato Scientific.
Chamber walls use 14-gauge zinc-coated galvanized steel, while the exterior is 16-gauge steel finished in powder-coated cool gray. Cascade refrigeration pairs two hermetic compressors with CFC-free R-508B and R-404A refrigerants. Air-cooled condensing with two heavy-duty fans removes any need for liquid coolant. A 1/2" access porthole sits on the left-hand cabinet wall with plugs.

How to Choose the Right Ultra-Low Freezer
Selecting an ultra-low freezer means matching storage demands to refrigeration performance and site constraints. Weigh these axes.
- Temperature range: confirm the unit holds your samples' required set point; this model spans -40°C to -80°C.
- Voltage compatibility: verify facility power; this freezer supports 115V, 208V, 230V, and 220V configurations.
- Footprint and access: chest-style loading and a 91" × 36" × 49" footprint must fit your lab layout and doorways.
- Defrost type: manual defrost requires scheduled maintenance compared with automatic systems.
