Macherey-Nagel pH-Fix Test Strips

Macherey-Nagel pH-Fix Test Strips enable even non-laboratory personnel to quickly and simply determine pH at the point of interest. The strips are suitable for use in the food industry, including sanitising solutions, milk, wine, beer, juices etc.

The strips, which cover the entire pH range, are available in 14 different measuring ranges to cover many applications and varying levels of sensitivity. Four distinct colour pads per test strip improve accuracy.

The dyes in pH-Fix test strips are chemically bound to the test pads and so the indicator dyes cannot bleed or mix with neighbouring test pads and colours can be precisely matched to a colour scale.

Also, pH-Fix technology prevents contamination of the sample by dye, so the solution can be re-used for further analysis. Even in weakly buffered solutions, pH-Fix test strips can be immersed for a long time until the final reaction colour has developed.
