BioMidi EF425

II 3G Ex nA nC nL llB T3 Gc

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.

Choosing the right product..

“Application” icons bridge the gap between product ranges and the requirements in the different segments, work environments and use patterns. Allowing for quick and precise evaluation of needs and requirements.


Customised to your needs

Every single user has a unique set of requirements for how a biostorage fridge or freezer should be configured, and how the interior should be laid out. That’s why there are no standard arrangements for cabinets in the BioLine range – it’d be highly unlikely that “standard” would live up to your particular working requirements.

Our approach is to make sure that all the BioLine cabinets featured have a high standard specification. 

We then provide you with a comprehensive selection of optional features, as well as standardised modules for internal arrangements, fittings and accessories. 
These choices enable you to select exactly what you need, and to customise both the operating specifications and the interior layout of your BioLine cabinets, so that they’re right in line with your particular requirements.

With a cabinets service life expected to be many years, we argue that using a little more time in selecting the configuration that suites your exact specifications, is worth it.

All BioLine cabinets have a flexible layout, and can be altered on a whim; and if the need should arise, you can easily acquire new fittings according to the changing needs.
