Description
DUOTEST pH 5,0 - 8,0 is indicator paper for rapid visual pH determination across the near-neutral window from 5,0 to 8,0. Dual-zone colour development enables quick comparison against the scale, helping users judge weakly acidic to mildly alkaline aqueous samples at the bench. The paper is delivered as a 5 m roll with a width of 10 mm, so strips can be cut to the working length required for each test. A pack comprises 5 rolls, supporting continuous use in quality control, education, and routine laboratory screening. Compact roll format simplifies storage and dispensing next to buffers and other indicator papers. From manufacturer Macherey-Nagel, this DUOTEST type fits process monitoring, buffer checks, culture-media control, and teaching exercises where results within the stated pH interval matter. It complements instrumental pH measurement as a fast first-pass tool and is listed among indicator and pH papers for general laboratory applications. Clear colour response and defined range make day-to-day sample triage efficient without complex preparation steps.

Questions about DUOTEST pH 5,0 - 8,0
What is this article?
DUOTEST pH 5,0 - 8,0 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 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.
