Beschrijving
Test ink pen blue arcotest® 43 mN/m is a ready-to-use blue test ink presented in pen form for surface wetting-tension checks at a defined level of 43 mN/m. The pen format allows direct application of the test fluid onto solid surfaces so that spreading or contraction behaviour can be observed immediately. Offered as 1 pc and weighing 0,020 kg, the unit is compact and suitable for bench-top or line-side use. Transport classification is indicated by UN number 3175. This arcotest® article from manufacturer Arcotest belongs to a graded series of blue test ink pens that differ only in their nominal surface-tension value, enabling stepwise evaluation of substrate energy. The intense blue colour improves visibility of the ink film during assessment. Laboratories and production teams can integrate the pen into incoming-goods inspection, process monitoring or comparative trials wherever a fixed 43 mN/m reference is required. Consistent single-piece packing supports reproducible handling from one test to the next without separate bottles or applicators.
This article is part of Test inks & surface tension, in Test kits & water analysis.

Questions about Test ink pen blue, arcotest® 43 mN/m, 1 unit(s)
What is this article?
Test ink pen blue, arcotest® 43 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 Chemicaliën.
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 Chemicaliën.
