WebA pH buffer is a reference solution of known pH value that is used for sensor calibration. pH buffers are key to ensuring accurate pH readings. Select from our comprehensive range of accurate pH calibration solutions, from technical buffers, buffers certified by an accredited body (DAkkS), to NIST/DIN buffers for high precision. WebThe pH range is 2.0~11.0. The most common system and pH range are shown in the following table: 4. HEPES buffer. HEPES is a non-ionic amphoteric buffer with good buffering capacity in the range of pH 7.2~7.4. It is commonly used in biochemical diagnostic kits, DNA/RNA extraction kits and PCR diagnostic kits. Table 1.
