Beschrijving
DUOTEST pH 3,5 – 6,8 is a pH indicator paper for rapid visual estimation of acidity in aqueous samples within a defined measuring window. The smallest measurable pH value is 3,5 and the largest is 6,8, so the rolls suit weakly acidic through near-neutral solutions commonly handled in laboratory and process-control work. Presented in roll form, the paper can be dispensed as needed for spot tests, bath checks and routine screening where full instrumental measurement is not required. This article is a refill pack containing three rolls, intended to replenish stock for ongoing pH-paper use. The commercial unit comprises two packages from manufacturer Macherey-Nagel, matching the stated minimum order quantity for efficient laboratory replenishment. DUOTEST belongs to the established indicator-paper and pH-paper families used across analytical, educational and quality-assurance environments. Each pack has a net weight of 0,02 kg and a compact footprint that simplifies storage and distribution. Laboratories that already rely on DUOTEST can maintain continuity of method simply by ordering this refill configuration for bench-side pH checks.

Questions about DUOTEST pH 3,5 - 6,8 refill
What is this article?
DUOTEST pH 3,5 - 6,8 refill 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 Chemicaliën.
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.
