FN 055/120

DRY HEAT STERILIZERSAir jacketed heating systemStainless steel chamberN-Prime™

With its advanced N-Prime™ microprocessor control system and PID temperature management, FN series offer very precise, constant temperature. The display shows large, bright characters, visible from far across the laboratory.

In sterilization mode, the user is warned if the device is out of the correct temperature range, due to power failure, etc. for peak performance sterilization.

Triple insulation reduces energy consumption while ensuring homogeneous temperature throughout the chamber.
