Description
VISOCOLOR ECO Potassium is a laboratory test kit for the determination of potassium ions in aqueous samples by turbidity measurement. With a measuring range of 2–15 mg/L K+, it addresses concentration windows commonly encountered in environmental water testing and related analytical work. Each pack supplies reagents and materials for 60 determinations, supporting efficient serial analyses in routine monitoring and quality-control programmes. The kit belongs to the VISOCOLOR ECO series from manufacturer Macherey-Nagel and is intended for straightforward handling with clearly defined working steps. Turbidimetric potassium assays help laboratories track dissolved K+ without complex instrumental setups, making the set suitable for both bench-top and field-oriented workflows. Typical use cases include surface water, process water and other aqueous matrices where potassium content is of interest. Supplied as one complete set, the product integrates easily into environmental analytics inventories and simplifies ordering for facilities that regularly screen for potassium. Clear evaluation guidance supports consistent results across repeated determinations in industrial and municipal laboratory environments.

Questions about VISO ECO Potassium
What is this article?
VISO ECO Potassium is the article on this page. Luminix Health distributes Macherey-Nagel for laboratory use. It sits in Colorimetric test kits, inside Test kits & water analysis, in Lab chemicals.
A colorimetric kit develops a colour whose intensity tracks concentration. Comparing by eye against a chart and reading a photometer are different versions. The range, the sample volume and the interfering substances named in the leaflet are the specification.
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.
Which category should I open next?
The category is Test kits & water analysis. The sub-category is Colorimetric test kits. The catalogue is Lab chemicals.
Shelves beside this one are Cuvette tests (Nanocolor), Test inks & surface tension and Test strips & indicator papers.
What should I check before I order?
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
