Description
DUOTEST pH 1 - 12 is indicator paper supplied as a roll for rapid estimation of pH values from 1 to 12 in aqueous laboratory samples. Each roll is 5 m long and 10 mm wide, allowing convenient dispensing of test segments for spot checks during preparation, process monitoring and quality screening. The roll format supports frequent measurements at the bench without the need for complex instrumentation for first-line acidity or alkalinity assessment. This product from manufacturer Macherey-Nagel is intended for general laboratory use in chemistry, environmental testing and quality-control settings where semi-quantitative pH indication is required before more precise instrumental analysis. Unit quantity is 5 rolls, matching typical replenishment needs for shared workstations. Compact packaging and a net weight of 0,03 kg keep storage and distribution straightforward across multiple benches. Clear pH range limits from 1 to 12 help operators select the paper for routine screening tasks where a broad measuring window is advantageous.
This article is part of Test strips & indicator papers, in Test kits & water analysis.

Questions about DUOTEST pH 1 - 12
What is this article?
DUOTEST pH 1 - 12 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 Produits chimiques.
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.
