Our product is delivered in concentration of 100 ppm (100 mg/L). This concentrate is possible to dilute to lower concentration (usually 5-20 ppm) by demineralised/distilled water. Please do not use ordinary tap-water for the dilution, it may cause agglomeration of nanoparticles and inhibit product efficiency. We offer 3 various packages of our product to our clients in USA, Canada and EU. Please contact us directly for B2B offers, if you need higher volumes or if you are from other countries.
