Standard in our industry

These are the gold standard for dyne testing. The distinction between wetting and beading is clear, making it easy to train new employees on surface prep.

Reliable cleanliness detection

Excellent tool for verifying cleaning processes on metal parts. If the ink beads up, we know there is still oil present. Very intuitive to use for floor staff.

Essential for our QC lab

We use these pens daily to check surface energy on plastic films before printing. The German BABTEST models are incredibly consistent and the ink flow is perfect every time.

Perfect for R&D

We use these to test new coating formulations. The precision helps us dial in the exact surface tension required for adhesion. Highly recommended for research teams.

Decent but pricey

The quality is undeniable, especially the USA A.Shine versions, but the cost adds up if you need to replace them frequently due to evaporation.

Good range, fast shipping

Ordered the full set from 18 to 72. Most pens work great. One pen near the higher range seemed a bit dry upon arrival, but customer service replaced it quickly.

5 FAQ

Q: Are replacement tips available for these pens?

A: No, the applicator tips are integrated into the pen body. Once the fluid is depleted or the tip is damaged, the entire pen unit needs to be replaced.

Q: Can these pens be used on curved surfaces?

A: Yes, the pen tip is designed to apply a thin line even on slightly curved or irregular surfaces, provided the area is accessible and clean.

Q: Is this product safe to use on food packaging materials?

A: Yes, once the test fluid has fully evaporated, it leaves no residue that affects food safety. However, ensure the tested area is dry before contact with food products.

Q: How should these pens be stored to maximize shelf life?

A: Store the pens horizontally in a cool, dry place away from direct sunlight. Ensure the cap is tightly sealed immediately after each use to prevent solvent evaporation.

Q: What does it mean if the ink beads up within 2 seconds?

A: If the ink beads up within 2 seconds, the surface tension of the material is lower than the value marked on the pen, indicating poor wettability or presence of contaminants.
