Heraeus BB 6220 CO2 Incubator. This incubator features particularly safe and stable long-term incubation conditions for excellent growth of cell and tissue cultures. The self-adjusting CO2 control system guarantees high consistency and long-term stability of the CO2 levels and therefore the pH value in the culture medium. It is 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 moisture vapor generation system is sterilized to avoid contamination. To ensure internal temperature consistency, the BB6220 features a microprocessor-based temperature controller and a platinum resistance temperature sensor (Pt 100).
