Beschrijving
pH indicator sticks covering the range pH 5.0–10.0 support visual assessment in the near-neutral to moderately alkaline region. Non-bleeding strips are supplied for immersion testing with colour matching to a graduated scale: 5,0 - 5.5 - 6.0 - 6.5 - 7.0 - 7.5 - 8.0 - 8.5 - 9.0 - 9.5 - 10.0. Half-unit steps give finer orientation than whole-unit universal papers within this window, which is useful for buffer checks, culture media orientation and process samples that typically fall between mildly acidic and alkaline conditions. The non-bleeding formulation helps maintain distinct colour zones and reduces dye bleed into the test liquid. A plastic box contains 100 strips, suitable for repeated bench use in teaching and routine laboratory workflows. These indicator sticks from manufacturer Marienfeld form part of standard laboratory material for instrument-free pH screening when a focused mid-range scale is preferred. Compact plastic packaging keeps the strips protected in storage and ready for quick access during series of measurements.
This article belongs on Test strips & indicator papers, in Test kits & water analysis.

Questions about pH universal indicator strips,
What is this article?
pH universal indicator strips, is the article on this page. Luminix Health distributes Marienfeld for laboratory use. It sits in Test strips & indicator papers, inside Test kits & water analysis, in Chemicaliën.
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.
