This product is deionized and distilled during production, but it is not guaranteed to be completely ion-free as ICP analysis is not performed. This product is sterilized by 0.2 µm sterile filtration rather than autoclaving. Sterility testing is performed and confirmed in the product Certificate of Analysis.
