Product details

Resembling the regular 425, the EF is a low temperature freezer capable of running at -40°C. The “EF” (extended freezer) model range comes standard with a handle for secure closing, and PMMA inner doors for maximum cold retention during door openings. Despite this different operating range, the EF425 retains the benefits inherent to the 425 cabinet, relatively small size, ergonomics and performance.

The BioMidi EF425 is solely available as the -40°C/-5°C model, and comes in stainless/aluminium or all stainless interior and white or all stainless exterior.
