The pH 10.01 buffer is the most popular buffer used before analysing basic samples. Ideal for those requiring an accurate alkaline reading, particularly suitable for those working in water purification plants, the food industry, aquatics, and hydroponics, and in any environments where the pH is expected to be alkaline. Hanna microprocessor pH meters can be calibrated at pH 9.18 and pH 10.01. To correctly maintain your meter/electrode, the use of a Hanna Instruments cleaning solution, as well as a buffer, for maximum performance every time is recommended. pH 4, along with pH 7, can also be used as an emergency storage solution.

• Buffer solutions should be stored at 25°C, away from direct sunlight for accurate readings
• Prepared, ready-to-use, according to precise formulas and standardised in accordance with the National Institute of Standards and Technology (NIST) to ensure quality and accuracy
• All solutions show a batch number, an expiry date, and the correlation table between pH and temperature
• A certificate of analysis is available
• All bottled solutions are sealed with an air tight, tamper-proof seal to prevent any carbon dioxide from entering and causing a change in the pH buffer value
