Perfect for lab work
Our laboratory uses these daily for adhesion testing. The fast-drying formula saves us time, and the accuracy is spot-on compared to our liquid test kits.

Great for printing prep
Ensures our substrates are ready for printing without any guesswork. The 38 dyne marker is perfect for our specific film requirements. Will buy again.

Essential for quality control
This German-made dyne pen is incredibly reliable for our packaging line. The 38 dyne level test fluid dries quickly and gives a clear result every time. Highly recommended for industrial use.

Good precision, fast shipping
Works exactly as described for checking corona treatment on polyethylene films. The only reason for 4 stars is the price, but the quality justifies it.

Superior to generic brands
We switched from a cheaper brand to this BABTEST pen and the consistency is much better. No more ambiguous wetting results. The felt tip holds up well even after hundreds of tests.

Reliable tool
Solid construction and accurate readings. Make sure to cap it immediately after use to prevent evaporation, which is standard for all dyne pens.
Q: How long does the test fluid last once the pen is opened?
A: If kept tightly capped when not in use, the fluid typically remains effective for 6 to 12 months depending on storage conditions and frequency of use.
Q: Does this pen come with a calibration certificate?
A: Yes, each BABTEST Dyne Pen batch is tested for accuracy, and a certificate of conformity is available upon request from the manufacturer.
Q: Can this be used on metal surfaces?
A: While primarily designed for plastics and films, it can be used on coated metal surfaces to test the efficacy of pre-treatment or cleaning processes.
Q: Is the fluid toxic or hazardous?
A: The fluid contains formamide and should be handled with care. Please refer to the Safety Data Sheet (SDS) included with the product for detailed safety information.
Q: What is the difference between the 38 and 42 dyne pens?
A: The number indicates the surface tension level in mN/m that the fluid tests for. You select the pen based on the minimum dyne level required for your specific adhesive or ink to bond properly.
