ross-contamination during amplification of DNA and RNA can lead to results that are inaccurate. These results consume valuable time and expensive reagents. AirClean® PCR hoods protect sensitive reactions from airborne contaminants. Each system has a built-in 254 nm ultraviolet light for decontamination of consumables and equipment between amplifications. Combination workstations include vertical laminar flow action to prevent outside contaminants from entering the work area during manipulation.
