Description
Litmus paper refill packs in the red form provide convenient qualitative pH indication for routine laboratory screening. The papers are delivered as 5 m rolls, 10 mm wide, and are specified for the pH range 5–8, enabling quick visual assessment of aqueous samples near the neutral region. A pack contains 3 rolls, ready for use in dispensers or for preparation of individual strips. Colour change of the red litmus indicator reflects the acid–base character of the test solution and supports day-to-day checks in education, quality control and general analytical settings. These refill packs from manufacturer MACHEREY-NAGEL are intended to keep classic pH papers available with minimal packaging overhead. The unit weight is 0,020 kg, so the rolls fit easily among other indicator papers and pH-related labware. Applications align with measuring instruments for pH value and with standard pH paper workflows where simple, instrument-free indication is preferred. Uniform roll length and width help standardise handling across workstations and teaching benches.

Questions about Litmus papers, refill packs, 5 m rolls, W 10 mm, red pH 5 - 8, 3 roll(s)
What is this article?
Litmus papers, refill packs, 5 m rolls, W 10 mm, red pH 5 - 8, 3 roll(s) 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.
