pH 4.01 buffer is one of the most commonly used buffer solutions as it is extremely stable and represents a mid-way point in the pH scale.

Hanna buffer solutions are prepared according to precise formulas and are standardised with a pH meter calibrated according to NIST standards. All solutions show batch number, expiration date and the correlation table between pH and temperature.
