We stock a wide range of acidic and alkaline buffer solutions (also known as pH buffers) to help you achieve accurate measurements. Available in a number of different values and suitable for checking pH testing devices and electrodes to ensure they are reading correctly.

An aqueous solution capable of resisting significant pH level changes, a buffer maintains the same pH when an external base or acid is added to it. The capacity of the buffer is essentially the amount of the external base or acid that can be added without altering the pH in a substantial manner. Buffer solutions are useful for checking that your instruments such as your electrodes are properly calibrated and will therefore deliver accurate results. They are also helpful for performing chemical analysis, among other applications.

Whether you’re looking for colour-coded capsules or buffer solutions, we’ve got you covered.

We also stock high-quality storage and cleaning electrode solutions, which are key to maintaining your devices in the best condition, and are very easy to use.
