Essential for our QA process
We use these pens daily to verify corona treatment levels on our packaging films. The 38 dyne level is consistent, and the quick-dry feature speeds up our inspection line significantly.

Good consistency
I've ordered these three times now, and the performance remains consistent across batches. The felt tip holds enough fluid for several hundred tests.

Perfect for plastic printing prep
Before running large print jobs, we test the surface tension with this pen. It beads or spreads exactly as expected at 38 dynes. Highly recommended for print shops.

Reliable but pricey
The accuracy is spot on compared to our lab equipment. The anti-counterfeit feature gives us confidence we are buying genuine products, though the price is slightly higher than generic brands.

Fast drying is a game changer
The quick-dry formula means we don't have to wait around for results. It allows our technicians to move immediately to the next sample without smudging.
Q: Does this pen work on treated polyethylene films?
A: Yes, the Dyne Test Pen 38 is specifically designed to test surface tension on treated plastics like polyethylene and polypropylene films.
Q: Can I use this to test metal surfaces?
A: While primarily for polymers, it can indicate cleanliness on metals, but dyne levels are standardly used for measuring surface energy on non-porous plastics and coatings.
Q: How long does the ink take to dry?
A: The formula is engineered to be quick-dry, typically evaporating within 2 to 4 seconds under normal room conditions, allowing for immediate assessment.
Q: What does the anti-counterfeit feature look like?
A: Genuine pens include specific holographic labeling and unique batch codes on the barrel that can be verified through our official website.
Q: Is the refillable?
A: No, these test pens are disposable units designed to maintain strict calibration accuracy throughout their lifespan. Once the ink is depleted, the entire pen should be replaced.
