Click2Contact

GFL ultralow freezers, fully manufactured in Germany, are available from Capella Science. The range includes features such as: lockable control panel; full stainless-steel interior; powder-coated galvanised steel exterior; explosion-proof design; RS232 interface for logging and remote control via lab management software; remote alarm contacts; 60-hour battery backup; user-adjustable over/undertemperature alarm settings.

The freezers are also environmentally friendly, with CFC-free refrigerant and insulation and low noise and heat output. This reduces the load on building-maintenance systems.

There are six models in the chest freezer range, from 30 to 500 L. The three upright models include a 500, 300 and 96 L under-bench model. The company also offers a corresponding range of -40°C freezers in the same sizes.

Optional extras include: extra shelves; drawers instead of shelves; LN2/CO2 backup systems; chart recorders; complete inventory systems; a water-cooling option (using mains-water supply or chilled water) which is said to facilitate operation in higher ambient temperatures than other freezers.
