pH indicator papers ‑ standard for many applications
pH indicator papers have been available for decades and are the standard for many applications. For each pH value these papers show a single color which can be matched with the color scale at intervals of 0.2 – 1 pH units. The indicator papers come in plastic reels that ensure long‑term stability and protection against many external influences. They will be always ready‑to‑use when needed.
MACHEREY‑NAGEL also controls the production of the raw papers which ensures – in combination with our ISO 9001 QC system – the high quality of the indicator papers.
The colors of the scales are specially mixed to perfectly match the reaction color of the indicator papers. This makes the reading of results easy and accurate.
