Description
RAPIDTEST 38® is an arcotest® surface-tension test pen set to 38 mN/m for fast, targeted evaluation of surface energy on films, plastics and other solid substrates. The 5 ml test-pen format delivers controlled application of the test fluid, allowing operators to judge wetting or beading behaviour against the defined dyne level in a single stroke. It is suited to incoming inspection, process monitoring and pre-treatment checks where surface tension must be verified before coating, printing or adhesive bonding. Packaged as one piece with a net weight of 0,022 kg, the pen supports portable use at the bench or on the production line. The preparation is supplied from manufacturer Arcotest and carries UN number 3175. Typical laboratory contexts include determination of physical properties and surface-tension characterisation within analytical and quality workflows. Use in accordance with the safety data provided for the formulation. RAPIDTEST 38® offers a compact pen solution for consistent 38 mN/m screening without complex instrumentation.
This article belongs on Test inks & surface tension, in Test kits & water analysis.

Questions about RAPIDTEST 38®, arcotest® 38 mN/m, 5 ml test pen, UN-Nr. 3175
What is this article?
RAPIDTEST 38®, arcotest® 38 mN/m, 5 ml test pen, UN-Nr. 3175 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.
