Description
DUOTEST pH 1,0 - 4,3 is an indicator paper for rapid visual determination of pH in the acidic measuring range from 1,0 to 4,3. It is supplied as a roll of 5 m length and 10 mm width, allowing convenient preparation of individual test strips for routine checks. This DUOTEST paper from manufacturer Macherey-Nagel is suited to chemistry, quality-control and teaching laboratories that need a quick orientation measurement without electronic meters. The defined window between the smallest measurable pH value of 1,0 and the largest of 4,3 focuses on strongly acidic samples, reagents and process solutions. The roll format supports economical use and compact bench storage. Units are offered as rolls, with a minimum order quantity of 5 pieces. Net and gross weight are each approximately 0,03 kg. Non-sterile by design, the paper is intended for general laboratory indicator work rather than aseptic procedures. Clear colour transitions on the dual-test strip enable straightforward comparison for everyday acidity screening in chemical and process environments.
This article is part of Test strips & indicator papers, in Test kits & water analysis.

Questions about DUOTEST pH 1,0 - 4,3
What is this article?
DUOTEST pH 1,0 - 4,3 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.
