When pH is part of your quality-control routine, having the right tools available can make the process easier.

pH buffer solutions are designed to provide known pH reference points, helping users work with their pH measurement equipment as part of routine testing and checking.

Easy identification

The colour-coded solutions make selection straightforward:

Simple handling

The supplied SDS information describes both products as liquid solutions and indicates that they are miscible with water.

For storage, the SDS advises keeping the containers tightly closed; the pH 4 solution should be kept in a cool, well-ventilated area, while the pH 7 solution should be protected from direct sunlight.

A small product with an important role

pH buffer solutions may be simple products, but they can form an important part of a consistent pH measurement routine.

When pH matters, start with a reliable reference.
