A 50ml sample of contaminated "toilet water" was sent to an independent laboratory along with 5 batches of ionic-colloidal silver made by the Silver Pulser. The following is the report from CanTest Ltd. Professional Analytical Services, Vancouver. In all cases the toilet water sample had less than detectable levels of CFUs (Colony-forming Units) present after being exposed to ionic-colloidal silver generated by the Silver Pulser.
