Description
Litmus paper blue in roll form is a classic qualitative indicator paper for simple acid–base checks in the laboratory. Each roll measures 5 m in length and 7 mm in width, so strips can be cut to the length needed for sample spotting, rinse testing or teaching demonstrations. Blue litmus is the conventional form used to indicate acidic reaction by a colour change, supporting quick go/no-go assessments alongside other pH tools. The product is supplied by manufacturer Macherey-Nagel and is offered with a minimum take-off of five rolls, matching routine stocking for teaching labs, QC benches and general wet chemistry. Compact roll format keeps the paper clean and easy to dispense compared with loose sheets. Use the paper for approximate indication only as part of standard laboratory practice; pair with calibrated methods when quantitative pH values are required. This blue litmus roll is a practical consumable for everyday qualitative acid detection and basic chemistry workflows.
This article is part of Test strips & indicator papers, in Test kits & water analysis.

Questions about Litmus paper blue (5m reel)
What is this article?
Litmus paper blue (5m reel) 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.
