pH value is affected by temperature variations. A temperature/pH reference chart is provided on the bottle label for reference.
All the solutions are double-sealed, not subject to the DOT shipping restrictions, and have a 2-year shelf life. The expiration date is printed on the bottle. MSDS documents are downloadable.
