Description
Litmus paper red is a classic laboratory indicator paper supplied in a bottle with 200 strips for rapid qualitative acid–base evaluation. The strips change from red to blue across the transition range 5,0–8,0, offering a clear visual signal when conditions move from acidic toward alkaline. This red litmus format is well suited to routine bench checks, teaching laboratories, and general wet-chemistry applications where simple colour indication is preferred. Each pack contains 200 ready-to-use strips in a practical bottle, supporting efficient sample screening and solution verification without instrumentation. Indicator papers from manufacturer filtraTECH fit everyday laboratory material needs for qualitative analysis and educational demonstrations. The characteristic red-to-blue shift is particularly helpful when confirming alkalinity at a glance during preparation or control steps. Compact packaging keeps the strips accessible and organised, providing a reliable consumable stock for standard laboratory workflows and quality-control spot tests.
This article is part of Test strips & indicator papers, in Test kits & water analysis.

Questions about Indicator paper, bottle with 200 strips, red litmus paper
What is this article?
Indicator paper, bottle with 200 strips, red 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.
