STANDARDS, PH BUFFER SOLUTIONS
pH measurements are probably the most common of all routine laboratory tasks. As pH affects all chemical and biochemical reactions, it is very important to have a reliable measurement. pH meters measure the voltage between two electrodes immersed in a sample and compare it to values measured with the same electrode pair in standard solutions.rrScharlau standard buffer solutions are accurate, stable and directly traceable to NIST. They are measured performing a multiple-point calibration according to DIN 19268. The calibration standards are prepared according to DIN 19266.
