Description
RAPIDTEST 38® is an arcotest® surface-tension test pen adjusted to 38 mN/m and supplied in a 15 ml Test Pen Jumbo format for extended use during surface-energy checks. The jumbo pen applies the test liquid in a controlled line so that spreading or retraction can be read against the fixed dyne value, supporting decisions on wettability prior to printing, lacquering or bonding. With a pack size of one piece and a net weight of 0,040 kg, the larger fill volume suits higher-throughput laboratory or production environments that require frequent comparative tests. The product comes from manufacturer Arcotest and is assigned UN number 3175. It belongs to application areas covering determination of physical properties and surface tension measurement. Operators obtain a practical indication of whether a substrate meets or falls below the 38 mN/m level without specialised analytical hardware. Always consult the linked safety documentation before handling. RAPIDTEST 38® in the 15 ml jumbo pen configuration combines defined dyne specification with convenient, repeatable application for routine surface screening.

Questions about RAPIDTEST 38®, arcotest® 38 mN/m, 15 ml Test Pen Jumbo, UN-Nr. 3175
What is this article?
RAPIDTEST 38®, arcotest® 38 mN/m, 15 ml Test Pen Jumbo, 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.
