Beschrijving
Special indicator paper pH 3,8–5,8 is a dedicated test paper for rapid visual pH assessment in the weakly acidic range. Designed as refill rolls for laboratory and process use, it supports clear stepwise readings across the stated measuring interval pH 3,8–3,8–4,1–4,3–4,5–4,7–4,9–5,2–5,5–5,8 and above 5,8. Each roll measures 5 m in length and 7 mm in width, allowing convenient tear-off strips for routine sample checks in chemistry, quality control, and educational settings. Supplied as a refill pack containing three rolls from manufacturer Macherey-Nagel, the format is intended for continuous bench or field work where indicator paper is used frequently. The compact roll form keeps the active paper protected until needed and simplifies storage beside other pH papers. Minimum order quantity is two packages. This special indicator paper complements broader pH paper assortments when a focused window around pH 3,8 to 5,8 is required for titration endpoints, buffer verification, or aqueous sample screening.
This article is part of Test strips & indicator papers, in Test kits & water analysis.

Questions about Spec. ind. pH 3.8-5.8, reel, refill
What is this article?
Spec. ind. pH 3.8-5.8, reel, 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.
