Pickering Laboratories Inc Artificial Perspiration, ISO 12870, Custom pH, Not Stabilized, each (200 mL/bottle)

Perspiration is on everything we touch with our fingers or that comes into contact with our bodies. Sweat can react with materials and trigger allergies, or it can shorten product service life via corrosion or discoloration. Natural human perspiration has a complex composition that depends on the type of sweat gland, the person’s metabolism and hydration level. This solution is used to determine the resistance to perspiration of unglazed spectacle frames designed for use with all prescription lenses and also to rimless mounts, semi-rimless mounts and folding spectacle frames. This is also applicable to frames made from natural organic materials, but not to custom-made spectacle frames or to products designed specifically to provide personal eye protection. Provided at a pH level of your choosing
