Looking after a pH electrode doesn't have to be complicated.

A simple routine can help make electrode care part of everyday laboratory practice.

🧼 STEP 1 – CLEAN

After use, cleaning can help remove material from the electrode and prepare it for storage or further use.

The Electrode Cleaning Solution is described as a clear, light-yellow solution and has a stated pH of 1.7 at 20°C.

💧 STEP 2 – STORE

When the electrode is not being used, use an appropriate electrode storage solution as part of your storage routine.

The Electrode Storage Solution is described as clear and colourless, with a stated pH of 1.7 at 20°C.

🔄 STEP 3 – REPEAT

Make cleaning and storage part of your normal pH measurement routine.

A little regular care can go a long way towards keeping your pH equipment ready for its next measurement.

Keep it simple

Use → Clean → Store → Repeat

That's the basic idea behind good electrode care.

The cleaning and storage solutions are supplied as separate products for their respective purposes, making it easy to include both in a routine electrode-care programme.

Good measurements start with equipment that's properly cared for.

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.

Not all pH measurements are the same, which is why different buffer values are useful.

🔴 pH 4.00 Buffer Solution

The pH 4.00 solution provides an acidic reference point.

It is supplied as a clear red liquid, making it easy to distinguish visually from the pH 7.00 solution. The supplied SDS lists its pH as 4.00 at 20°C.

🟡 pH 7.00 Buffer Solution

The pH 7.00 solution provides a neutral reference point.

It is supplied as a clear yellow liquid, with a stated pH of 7.00 at 20°C.

Why have both?

Having different reference points allows users to select the appropriate buffer solution for their pH measurement requirements.

The colour-coded appearance also makes the two solutions easy to tell apart at a glance.

At a glance:

Two colours. Two reference points. One important purpose – supporting accurate pH measurement.
