This buffer solution is intended for calibration work that uses a pH 4.01 reference point. The sachet format keeps each portion sealed until use, which helps limit contamination during bench or field work. Single use packets also make it easier to stage calibration supplies with portable meters, testers, and service kits. That makes this solution a practical choice for workflows that want clean, ready to use calibration portions without bottle handling.
