The Gram BioMidi RF425 laboratory freezer freezes reliably between -25 and -5 °C. Therefore you store samples, reagents and biological materials safely. At 600 mm wide, the cabinet takes little floor space. Furthermore, the ergonomic design supports daily use in laboratories and the pharmaceutical industry.
The RF425 uses the Gram BioLine air guidance system. As a result, the temperature stays stable throughout the cabinet. 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.
Smart defrost defrosts automatically and evaporates the meltwater. Thus maintenance stays limited. The cabinet also meets ATEX Cat.3 Zone 2, internally and externally. You configure the interior with:
