Description
Test ink blue is a surface-tension test fluid covering the arcotest® grades 30, 32, 34, 36, 38, 40 and 42 mN/m, supplied without brush for practical dyne testing on solid surfaces. These blue inks are used in quality-control and materials laboratories to assess wetting behaviour and surface energy of plastics, films, foils and coated substrates before bonding, printing or coating. By applying a thin film and observing whether it remains continuous or contracts into droplets, operators can quickly judge whether a surface meets a defined mN/m threshold. The set is offered as a 70 ml unit and is assigned UN number 1993 for transport classification. Clear blue colouration improves visibility on light-coloured materials and supports comparative checks across several dyne levels in one package. Available from manufacturer Arcotest, the inks fit routine pretreatment verification and process monitoring in industrial finishing and research environments. Consistent grade steps from 30 to 42 mN/m allow systematic mapping of surface energy windows relevant to adhesion and printability. Suitable for bench-top use wherever rapid, visual surface characterisation is required alongside other laboratory wetting and adhesion tests.
This article is part of Test inks & surface tension, in Test kits & water analysis.

Questions about Test ink blue, arcotest® 30 32 34 36 38 40 42 mN/m, without brush, UN-Nr. 1993
What is this article?
Test ink blue, arcotest® 30 32 34 36 38 40 42 mN/m, without brush, UN-Nr. 1993 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?

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.
