pH Buffer Solutions

pH buffer solutions are used to calibrate pH meters and electrodes, playing a crucial role in ensuring that these instruments provide accurate and reliable measurements.

Their function is to minimise the change in pH when base or acid is added to the buffer solution. They are able to neutralise small amounts of added acid or base, keeping the pH of the solution relatively stable and on a nearly constant value.

pH Buffer Solutions and Capsules are Colour-coded and have a longer shelf life. These solutions and capsules make it easier to regularly check whether your pH meter or tester is accurately calibrated, giving you the best possible results.

This range of ready-made buffer solutions is suitable for checking pH instrumentation and pH electrodes. The buffer capsules are slightly different and should be mixed with distilled water before use. Both the capsules and solutions come with different choices of pH levels.
