Questions about Test inks & surface tension

Which test ink (mN/m) do I need to check surface tension?

Test inks come in a series of values in mN/m. Start with the value your process requires, for example for printing, bonding or coating, and apply that ink to the surface. If the ink stays as a closed film for the time stated on the product page, the surface tension is at least that value; if it contracts into droplets, it is lower, so try a lower ink. Work up or down until you find the limit. A set of several values gives the most information. For other quick tests, see test strips and indicator papers. Questions? Ask sales@luminixhealth.com.

Test ink with brush or test ink pen: which is more practical?

A bottle with a brush gives the most reliable assessment: you apply a defined stroke on flat parts and can judge clearly whether the film holds, which suits quality control and incoming inspection. A test ink pen is faster and cleaner to carry, so it suits quick checks on the production floor and on parts in the line. Oil-free cotton swabs help to apply ink on small or curved areas without contaminating the surface. Keep caps closed, because evaporation changes the ink. For marking checked parts, see markers and pens. Questions? Ask sales@luminixhealth.com.

Why Test inks & surface tension?

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.

This shelf belongs to Test kits & water analysis, inside Lab chemicals. Luminix Health distributes this range for laboratory use.
