The Gram BioMidi RR425 laboratory refrigerator provides reliable cooling at +2 to +20 °C. With 425 litres and a 600 mm width, the cabinet is compact and energy-efficient. Moreover, the RR425 is ATEX-suitable and flexible to configure.
The Gram BioMidi RR425 laboratory refrigerator cools reliably between +2 and +20 °C. Therefore it suits the safe storage of medicines, reagents and samples. At only 600 mm wide, the cabinet saves valuable floor space. Furthermore, the ergonomic design supports daily intensive use in the pharmaceutical industry and medical diagnostics.
The RR425 uses the unique Gram BioLine air guidance system. As a result, the temperature stays even throughout the cabinet. The Gram BioLine MPC 4.6 controller regulates precisely and, if required, shows the product temperature via an extra E-sensor. Additionally, the controller stores the alarm history and drives a volt-free contact.
The cabinet meets ATEX Cat.3 Zone 2, both internally and externally. Thus placement in a potentially explosive atmosphere is permitted. You can configure the interior freely, for example with:
An optional double-glazed glass door makes the contents visible. Explore our full range of laboratory refrigerators or configure your unit via contact.
