DUOTEST pH 5,0 – 8,0 is a pH indicator paper for rapid visual estimation of acidity and mild alkalinity in aqueous samples. The measurable window runs from pH 5,0 to 8,0, covering near-neutral solutions frequently encountered in buffers, process liquors and routine laboratory checks. Supplied in roll form, the paper is easy to dispense for spot tests and screening whenever a quick colour-based reading is preferred to instrumental measurement. This item is a refill pack of three rolls, designed to restock existing DUOTEST use without changing established handling practice. The sales unit is two packages from manufacturer Macherey-Nagel, in line with the minimum order quantity for economical laboratory replenishment. As part of the indicator-paper and pH-paper category, DUOTEST supports analytical, teaching and quality-control workflows that need a simple, portable pH estimate. Net weight is 0,02 kg per pack, keeping the consumable compact for storage and distribution. Ordering this refill configuration helps laboratories keep continuous access to the 5,0–8,0 measuring range at the bench.

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