Description
DUOTEST pH 1 - 12 refill pack is dual-zone pH indicator paper for rapid semi-quantitative pH determination across the broad working range from 1 to 12. Supplied as a refill pack containing three rolls, it is intended to replenish existing DUOTEST dispensers used for routine visual pH checks. The dual-test design enables clear colour matching for reliable interpretation in laboratory, teaching, and process settings. This refill format from manufacturer Macherey-Nagel is offered with a minimum order of two packages and supports continuous availability of indicator paper without replacing the full dispenser unit. The product sits within the indicator-paper and pH-paper categories common to analytical chemistry, quality control, and industrial monitoring. Roll form allows users to tear off only the strip length required for each measurement, reducing waste. Suitable applications include general solution screening, bath monitoring, and educational demonstrations where a wide pH span and a simple visual method are required.
This article is part of Test strips & indicator papers, in Test kits & water analysis.

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