Description
Test ink pen blue arcotest® 68 mN/m is a ready-to-use laboratory test ink supplied in pen form for controlled, clean application. This blue grade is specified at a surface tension of 68 mN/m, giving users a clearly defined wetting level for routine surface checks and comparative evaluations. The single-piece pack keeps the medium ready at the bench without decanting from bulk containers, and the compact format supports tidy handling in quality-control and materials laboratories. Each unit weighs 0,020 kg, making it easy to store and move between workstations. Offered under the arcotest® line from manufacturer Arcotest, the pen presents the test ink in a practical applicator suited to discrete line or spot application. The blue colour improves visual recognition of applied traces during inspection. Unit quantity is 1 pc, ideal where only one defined tension grade is needed at a time. Clear 68 mN/m identification on the product helps operators select the correct pen for their protocol and maintain consistent test conditions across shifts and sites.

Questions about Test ink pen blue, arcotest® 68 mN/m, 1 unit(s)
What is this article?
Test ink pen blue, arcotest® 68 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 Produits chimiques.
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.
