The pH 10.01 buffer in a 1 Litre bottle is the most popular buffer used before analysing basic samples. Ideal for those requiring an accurate alkaline reading, particularly suitable for those working in surface water, groundwater and water purification plants.
Buffer solutions should be stored at 25 C, away from direct sunlight for accurate readings.
To correctly maintain your meter/electrode, we highly recommend use of a Hanna cleaning solution, as well as a buffer, for maximum performance every time. pH4, along with pH7, can also be used as an emergency storage solution.
