Description
Blue litmus paper test strips are simple qualitative indicator strips for situations where an exact pH value is not required. The blue paper changes colour to red when a solution shifts from alkaline to acidic, giving a clear visual cue for acid–base screening in teaching labs, routine chemical checks and quality-control workflows. Each plastic box holds ten booklets with twenty strips per booklet, providing two hundred ready-to-use tests in a compact format. These METRIA indicator papers from manufacturer Labbox belong to the classic litmus range used alongside red and neutral variants: red litmus turns blue under alkaline conditions, while neutral litmus turns red in acid or blue in base. Blue litmus is chosen specifically to detect the transition toward acidity without instrumentation. Net weight is 0,037 kg, so the pack is easy to store and share across benches. As indicator and pH papers they support everyday qualitative testing whenever a fast colour change is sufficient.
This article is part of Test strips & indicator papers, in Test kits & water analysis.

Questions about Litmus Blue Indicator paper, 10 books x 20 strips
What is this article?
Litmus Blue Indicator paper, 10 books x 20 strips is the article on this page. Luminix Health distributes Labbox for laboratory use. It sits in Test strips & indicator papers, inside Test kits & water analysis, in Produits chimiques de laboratoire et industriels.
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.
