Essential for our QC lab
We use these pens daily to test surface tension on polymer films before printing. The German quality is evident in the consistent ink flow and accurate dyne levels. Highly recommended for industrial quality control.

Perfect for corona treatment verification
Exactly what we needed to verify our corona treater settings. The range from 21 to 72 covers all our substrate needs. The distinction between wetting and beading is very clear.

Standard for our packaging unit
We standardized on these pens for all our incoming material inspections. The oil-based formula adheres well to various plastics without smudging. Excellent tool for ensuring print adhesion.

Reliable German engineering
I have tried other brands, but the BABTEST pens are far superior in consistency. The quick-dry formula saves us time on the production line. Will definitely reorder.

Good but pricey
The pen works as advertised and gives precise results for surface energy differentiation. However, it is slightly more expensive than competitors. You pay for the German origin and reliability.

Accurate but dries fast
The testing results are very reliable and match our lab equipment readings. The only downside is that the oil-based ink dries quite quickly if you leave the cap off even for a moment. Great product overall.
Q: What is the difference between this and water-based dyne pens?
A: Oil-based pens like this BABTEST model are generally more stable on non-porous surfaces and dry faster, reducing the chance of evaporation affecting the result during the test window. They are often preferred for high-speed industrial applications.
Q: How long does the ink last once the bottle is opened?
A: For best accuracy, we recommend using the pen within 6 months of opening. Always ensure the cap is tightly sealed immediately after use to prevent the oil-based ink from evaporating.
Q: Can I test multiple dyne levels with one pen?
A: No, each pen is calibrated to a specific dyne level (e.g., 38 mN/m). To test a range, you must purchase the specific set of pens covering the levels you require, such as the 21-72 range kit.
Q: Is the ink toxic?
A: The ink is oil-based and should be handled with care. Please avoid contact with eyes and skin, and use in a well-ventilated area. Refer to the Safety Data Sheet (SDS) included with the product for detailed safety information.
Q: Does this pen work on metal surfaces?
A: While primarily designed for plastics, films, and coated surfaces, it can be used on treated metals to check for cleanliness or coating presence, though standard dyne testing is most common for polymers.
