Thermo Scientific Revco™ ExF and DxF Series Ultra-Low Temperature Freezers are designed for daily sample protection and dependability. Choose the ExF models for applications requiring -50°C to -86°C, or a freezer from the DxF series for applications requiring a -10°C to -40°C range. All models deliver a wide variety of features including a state-of-the-art refrigeration system, rugged construction and easy-to-use microprocessor controls.
Freezers are made with a stainless steel interior in 13, 17, 23 cu. ft. sizes in both the ExF and DxF range, with the addition of a 28 cu.ft. ExF model to accommodate specific lab space and capacity requirements. Five interior compartment doors reduce cold air loss and improve temperature recovery after door closings.
All units feature heavy gauge, cold-rolled steel exterior construction with a powder coat paint finish that resists chipping and rust and 5" (127mm) foamed-in-place, polyurethane insulation. Optional CO2 or LN2 safety back-up system is available for additional protection in the event of a power or mechanical failure. Optional, built-in chart recorder for continuous monitoring. The sturdy, solid, stainless steel shelving is able to support a full product load and a vacuum relief port permits easy access after door openings. Additional features include the ergonomic, lockable door handle, a Power Management System with low voltage surge protection and buck/boost, and an easy-to-remove air filter. Each unit is equipped with two 25mm access ports.
The centralized information center, including microprocessor control and monitoring system, ensures that all controls and displays are easy to reach and read. Center is eye level on -86°C freezers or knee level on the -40°C freezers.
