Sachets are an extremely popular way of buying pH buffer solution. They are very portable, making them ideal for use in any outdoor testing application, each sachet is sealed until open, thus ensuring the solution is fresh and gives an accurate calibration. Another benefit is a long shelf life (shelf life is at least 2 years and is printed on each sachet).

All our buffer solutions are manufactured to established formulas and are standardized with a pH meter that is calibrated to the NIST primary standard buffer solutions. pH 7.01 buffer solution is certified traceable to NIST 185g S.R.M.
