The Gram BioLine BioMidi series offers reliable freezer storage for laboratories and pharmacy. BioLine air distribution keeps the temperature uniform. The cabinets are ATEX certified and energy-efficient. Suitable for professional use.
The Gram BioLine BioMidi series is developed for safe storage of temperature-sensitive products in laboratories and pharmaceutical environments. The series includes both standard freezers and a low-temperature freezer. Thanks to stable temperature control, these cabinets are suitable for daily storage of raw materials, reagents and pharmaceutical products.
All BioMidi models are equipped with the Gram BioLine air distribution system. This system guarantees uniform temperature distribution throughout the entire cabinet, with low energy consumption. The electronic Gram BioLine MPC control features product temperature display via an additional E-sensor, adjustable alarms and alarm history.
The BioMidi cabinets feature a robust construction with an underbuilt machine room for ergonomic use. All models comply with ATEX Cat.3 Zone 2 requirements, both internally and externally. The EF425 low-temperature freezer is supplied as standard with plexiglass draught doors to minimise cold loss during frequent access.
