Reliable but pricey
Great accuracy for testing surface energy on polyethylene films. It is more expensive than generic brands, but the results are trustworthy.

Perfect for lab work
Clear results every time. The felt tip holds up well even after multiple tests. Highly recommended for any laboratory setting.

Good product, fast drying
The pen works well, but I noticed the ink dries out faster than expected if the cap isn't secured immediately. Otherwise, accurate.

Essential for quality control
We use these pens daily in our packaging line to ensure proper adhesion before printing. The German engineering really shows in the consistency of the ink flow.

Excellent precision
We switched from a different brand and saw immediate improvement in test reliability. Worth every penny for critical applications.

Standard in our industry
This is the gold standard for dyne testing. Easy to read the wetting behavior within the required two-second window.
Q: Does this pen come with a calibration certificate?
A: Yes, each Arcotest pen comes with a batch-specific calibration certificate indicating the exact dyne level.
Q: Is the ink toxic?
A: The ink is formulated for industrial testing and should be handled with care. Please refer to the Safety Data Sheet (SDS) for detailed handling instructions.
Q: What is the difference between this and a contact angle meter?
A: Dyne pens provide a quick, pass/fail estimation of surface energy, whereas contact angle meters offer precise numerical data for research purposes.
Q: Can this be used on metal surfaces?
A: These pens are specifically designed for non-porous plastic films and foils. They are not intended for testing metal surfaces.
Q: How long does the ink last once the bottle is opened?
A: While the pen itself is sealed, we recommend using it within 12 months of purchase for optimal accuracy. Always recap tightly after use.
