pH‑Fix Unmatched pH test strips For many years untrained users as well as analytical professionals appreciate the experience of easy pH testing with pH‑Fix. In contrast to common indicator papers, the indicator dyes in pH‑Fix test strips are chemically bound to the test pads. This patented technology prevents bleeding of the dyes and therefore a contamination of the sample, even in highly alkaline solutions. The fixation enables the strips to remain in solution over extended periods of time allowing a safe pH determination even in weakly buffered solutions. Many customers receive our pH‑Fix test...

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...

pH papers with multiple indicator zones By the combination of several indicators on one test paper, a better recognition between different pH values is achieved. This makes the correct pH reading easier. Duotest - two indicator zones for higher accuracy Duotest indicator papers combine two different indicator zones on a single strip. The zones are separated by a hydrophobic barrier, which effectively prevents mixing of the reaction colors and increases the mechanical stability. Tritest - three indicator zones for highest precision Tritest indicator paper has three different indicator zones on...

QUANTOFIX® Semi-quantitative test strips QUANTOFIX® test strips meet all requirements of a modern rapid test. The color of the reactive pad changes depending on the concentration of an analyte in the sample. The evaluation is usually carried out visually by a comparison of the reaction color with a multi-stage color scale. Many customers receive our QUANTOFIX® test strips as OEM product. Easy analysis directly at the point of interest Analytical professionals as well as occasional testers appreciate QUANTOFIX® test strips for the fast and easy analysis directly at the point of interest. Often,...
