Description
Blue litmus indicator paper is a classic laboratory aid offered as continuous 5 m rolls for quick visual acid–base assessment. The paper changes from blue to red across the transition interval of pH 8,0–5,0, making it useful for detecting acidity, screening samples and teaching fundamental pH response. Users cut or tear strips from the roll to the length required for immersion or spot application, matching material use to each test. The pack comprises 10 pc(s), convenient for stocked benches in education, quality control and general laboratory work. Litmus impregnation of the paper substrate provides the well-known blue-to-red colour shift associated with acidic conditions. Supplied from manufacturer filtraTECH, the rolls integrate into everyday workflows where a simple, instrument-free indication method is preferred. Continuous format supports economical dispensing compared with only pre-cut strips when short pieces suffice. Specified colour behaviour is blue–red over the stated pH window, supporting straightforward interpretation under normal laboratory lighting. This product forms part of the indicator-paper range used for approximate pH determination in aqueous media and related lab applications.
This article is part of Test strips & indicator papers, in Test kits & water analysis.

Questions about Indicator paper, roll of 5 m length, blue litmus paper
What is this article?
Indicator paper, roll of 5 m length, blue litmus paper is the article on this page. Luminix Health distributes filtraTECH 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.
