Description
pH-Fix 1,7-3,8 is a pack of indicator sticks for rapid visual pH assessment in the mildly to moderately acidic range. The measuring interval extends from pH 1,7 to 3,8 with graduated colour steps at 1,7, 2,0, 2,3, 2,6, 2,9, 3,2, 3,5 and 3,8, supporting clear discrimination for process monitoring, sample screening and routine laboratory checks. Each test stick measures 5,5 × 85 mm and is intended for direct immersion followed by comparison with the reference scale. Packs contain 100 test sticks, providing a practical supply for teaching labs, quality control benches and field or plant measurements where electrode systems are not required. These pH-Fix sticks from manufacturer Macherey-Nagel deliver a convenient stick format that is easy to handle and suited to single-use testing. They are appropriate for acidic solutions, rinse waters and similar matrices falling within the stated pH window, offering a straightforward colourimetric alternative for quick orientation measurements.

Questions about pH-Fix 1.7-3.8
What is this article?
pH-Fix 1.7-3.8 is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Test strips & indicator papers, inside Test kits & water analysis, in Lab chemicals.
A test strip or indicator paper changes colour when it meets an ion, a pH or another analyte. It is a fast, coarse reading. The scale printed on the pack is the only scale that strip may be read against. A wet finger contaminates a pH paper before the sample does.
A test kit turns a chemical question into a colour, a titre or a reading on a strip, so the operator does not have to assemble the method from separate reagents. A cuvette test is a ready optical cell. A strip is a field reading. The range printed on the kit is the range where the answer means something. Outside it, the kit is silent or wrong. The substances inside are on PubChem. Water measurement traces to NIST.
