Thermo Scientific™ Safe 2020™ Class II Biological Safety Cabinets (BSC) enable you to protect samples in research labs, pharmaceutical quality control labs, pharmacies, and clinics. Combined with the Night-set-back mode (with reduced blower speed when the window is closed), the Thermo Scientific™ Safe 2020™ BSC consumes hundreds of kilowatts less energy than competing cabinets, reducing the lab carbon footprint and saving money.
