When using DNA amplification technologies, any traces of DNA originating from the equipment have to be eliminated. Vivacon® 500 PCR Grade units are treated with ethylene oxide (ETO) in a validated process in order to deactivate all traces of DNA that might interfere with subsequent amplification procedures.
