Perfect for printing prep

Using these to test substrates before flexographic printing has reduced our ink adhesion issues significantly. The 22-60 range covers all the materials we currently handle.

Accurate and consistent

We switched from a generic brand to these original arcotest pens and the difference in consistency is noticeable. No more ambiguous readings during our corona treatment checks.

Reliable tools

Very happy with the authenticity of these pens. They work exactly as described. I only wish the set included a few spare tips, but otherwise, it is a solid investment.

Industry standard for a reason

If you need precise dyne level measurements, do not compromise on cheap alternatives. These pens provide clear wetting behavior that is easy to interpret immediately after application.

Essential for our QC lab

These genuine German pens are a staple in our quality control process. The color coding makes it incredibly fast to determine surface energy on our packaging films. Highly reliable results every time.

Great product, fast shipping

The mixed color set covers our entire testing range perfectly. One pen arrived with a slightly loose cap, but it still functions well. Overall very satisfied with the purchase.

5 FAQ

Q: Does this set include a certificate of calibration?

A: Yes, as an authorized distributor, our original import sets come with documentation verifying their authenticity and manufacturing standards compliant with German specifications.

Q: Are these pens suitable for testing metal surfaces?

A: These pens are primarily designed for non-absorbent materials like plastics, films, and foils. While they can technically be used on smooth metals, they are optimized for polymer surface tension testing.

Q: What does it mean if the liquid beads up instead of spreading?

A: If the liquid beads up within two seconds, the surface tension of the material is lower than the value marked on the pen. You should try a pen with a lower mN/m rating to find the matching level.

Q: Can I refill these pens once the ink runs out?

A: No, arcotest Dyne Pens are designed as single-use disposable tools to ensure accuracy and prevent contamination of the test fluid. Refilling is not recommended and may void accuracy guarantees.

Q: How should I store these pens to maximize their shelf life?

A: Please store the pens horizontally in a cool, dry place away from direct sunlight and heat sources. Ensure the caps are tightly sealed immediately after each use to prevent evaporation.
