Perfect for our lab needs

We needed empty pens to test specific custom dyne levels in our packaging department. This red pen works flawlessly with our imported ink solutions. The felt tip distributes liquid evenly without bleeding.

Reliable tool

Does exactly what it is supposed to do. The red color makes it easy to distinguish from our other testing tools on the workbench. Good value.

Great for custom testing

We often need to test non-standard dyne levels that pre-filled pens don't offer. This empty pen is the perfect solution. Very satisfied with the purchase.

Exactly as described

Bought these to replace our old worn-out testers. They fit our standard ink bottles perfectly. No leaks and the marker tip is consistent.

Essential for quality control

As a print shop owner, verifying surface tension is daily routine. These empty pens allow us to mix precise dyne values. Highly recommended for professional use.

Good quality, fast shipping

The build quality is solid for the price. It feels sturdy in hand. I deducted one star only because the cap was slightly tight upon arrival, but it loosened up after a few uses.

5 FAQ

Q: Does this pen come with any ink included?

A: No, this product is an empty pen body designed to be filled with your own specific dyne ink solutions.

Q: How do I clean the pen before filling it with a new dyne value?

A: Please flush the pen with isopropyl alcohol and let it dry completely before adding new ink to ensure no cross-contamination of dyne levels.

Q: Can I use generic marker ink instead of dyne ink?

A: While physically possible, we strongly recommend using certified dyne ink for accurate surface tension measurements. Generic inks may yield incorrect results.

Q: Is the tip replaceable if it gets damaged?

A: The felt tip is press-fit and can be replaced with standard marker tips of similar size if necessary, though replacement tips are sold separately.

Q: What is the approximate capacity of the pen reservoir?

A: The internal reservoir holds approximately 3-4 ml of liquid, which is standard for small domestic test pens.
