The Gram BioMidi EF425 low-temperature freezer reaches -40 °C for safe storage of sensitive samples. Standard acrylic draught doors reduce cold loss. Moreover, the EF425 is ATEX-suitable and recovers temperature quickly after opening.
The Gram BioMidi EF425 low-temperature freezer reaches temperatures between -40 and -5 °C. Therefore you store sensitive biological samples safely. The high-capacity cooling system also ensures fast temperature recovery after door opening. Thus the contents stay protected in laboratories and the pharmaceutical industry.
The EF425 comes with acrylic draught doors as standard. As a result, cold loss on opening stays limited. The Gram BioLine MPC 4.6 controller regulates precisely and monitors upper and lower limits. Additionally, the controller stores the alarm history and drives a volt-free contact.
The cabinet meets ATEX Cat.3 Zone 2, internally and externally. Thus placement in a potentially explosive atmosphere is permitted. You configure the interior with:
