Glass/steel door high-volume refrigerators with forced air cooling. White steel exterior and stainless-steel interior. Choose between two temperature stability options to suit differing laboratory requirements. The intuitive user interfaces provide useful extended multi-functionality, e.g. a maintenance timer, and the LED interior lighting ensures good visibility of the contents of these large appliances. Advanced connectivity options to suit varying requirements for simplified data storage, temperature control and alarm signals. These advanced lab fridges also feature a +2 °C safety device to protect sensitive contents from freezing.

Perfection series ±2 K deviation from setpoint and DIN 13277 compliance. Both with calibration function. All models are available in Perfection series. Glass door versions are optimised for improved display area and a better overview of the contents.

Certifications: IEC 61010-2-011 standard refrigerators specially developed for storing temperature-sensitive products are CE safety-compliant. This ensures that all mechanical and electrical requirements for injury-free operation are met and that the team are always safe. Perfection series comply with DIN 13277.
