Ideal for environments that demand the highest levels of sample integrity and reproduction including microbiology, cancer research, tissue engineering and in-vitro fertilization.The entire humidity vapor generation system is sterilized to prevent contamination.To ensure internal temperature consistency, the BB6220 features a microprocessor-based temperature controller and a platinum resistance (Pt 100) temperature sensor.The BB6220 features a second, completely independent controller with its own temperature sensor. In the event of a fault, the back-up controller automatically takes over to protect cell cultures from overheating.
