Description
Test ink pen blue, arcotest® 35 mN/m is a ready-to-use laboratory pen filled with blue test ink set to a defined surface tension of 35 mN/m. It supports rapid visual assessment of surface energy and wetting behaviour on solid materials in quality control and materials testing. The ink’s blue colour improves contrast on many substrates, helping operators judge whether a surface meets the target treatment level. Each item is supplied as 1 pc and has a weight of 0,020 kg, so it is easy to keep at the bench or on the line without bulk liquid handling. This arcotest® pen from manufacturer Arcotest is associated with UN number 3175 and is intended for discrete, level-specific surface checks. Apply a short stroke, observe the film behaviour, and compare the result with the stated 35 mN/m value according to established surface-tension test practice. The single-unit format suits individual workstations, method kits and routine inspection of treated or untreated surfaces where a portable 35 mN/m reference is required.
This article is part of Test inks & surface tension, in Test kits & water analysis.

Questions about Test ink pen blue, arcotest® 35 mN/m, 1 unit(s)
What is this article?
Test ink pen blue, arcotest® 35 mN/m, 1 unit(s) is the article on this page. Luminix Health distributes Arcotest for laboratory use. It sits in Test inks & surface tension, inside Test kits & water analysis, in Lab chemicals.
A test ink checks the surface energy of a solid: the ink either wets the surface or crawls back. The stated dyne value is the product. It is a surface-treatment check, used on plastics and films, not an assay of a liquid concentration.
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 Test inks & surface tension. The catalogue is Lab chemicals.
Shelves beside this one are Cuvette tests (Nanocolor), Colorimetric test kits and Test strips & indicator papers.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
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.
