pH Wide (0-14) Test Strips, 100, Macherey-Nagel made in Germany - Phwide/A1

pH-determination quick, easy, safe

With pH-Fix test strips, you can test the pH value quickly and easily directly at the point of interest. The strips are ready to use at any time and don’t need any calibration, set-up or maintenance. Therefore, pH determination with pH-Fix test strips is very easy, regardless of your experience or chemical background.

Safe analysis by long plastic handle

The long plastic handle safely protects you from coming into contact with the sample. Thus, testing toxic, dangerous or aggressive substances is safely possible.

Several test pads for exact results

pH-Fix indicator test strips feature up to 4 different indicator pads that cover the whole pH range from 0–14. You can chose from a total of 14 different measuring ranges to find the ideal strip for your application. The brilliant color scale is optimally matched and aligned to the test pads on the strips, resulting in quick, easy and safe pH determination.

No bleeding due to color bounded indicator dyes

In contrast to common indicator papers, the indicator dyes in pH-Fix test strips are chemically bound to the test pads. This patented technology safely prevents bleeding of dyes into the sample, even in highly alkaline solutions. Your sample is not contaminated by indicator dyes. Consequently, you can use the solution for further analysis.

The special non-bleeding technology provides additional benefits for you:

• Even in weakly buffered solutions, a safe and reliable pH determination becomes possible,
as the strips can be immersed for a long time until the final reaction color has developed

• The colors of the individual test pads don’t bleed and mix, which assures exact comparison
to the color scale

• Your sample is not contaminated by indicator dyes
