Surface Test Equipment

Easy Test Dyne Pens

Easy test Dyne pens allow you to quickly identify if the surface energy of a test part is >72mN/m. Surface energy is the property of a surface arising from unbalanced molecular forces at or near the surface, compared to those in the bulk material, and provides a quick indication of adhesion characteristics and wettability.

Easy test Dyne pens and how they work – If a liquid is applied to the surface and its surface energy is higher than the surface energy of a material to which it is applied then the liquid tends to form droplets. If the surface energy of the liquid is lower than that of the surface to which it is applied it will spread out or “wet” the surface evenly.


Dyne Pens

The pens are filled with a Dyne test fluid of 72mN/m surface tension. The pen is drawn across a plasma-treated surface and if the liquid draws together or forms beads on the surface then the surface energy is less than 72mN/m, indicating that the plasma treatment has not been performed.

Easy Test Dyne Pens are available off the shelf for next day delivery.


Surface Energy Test Inks

Surface Energy Test Inks provide an accurate measurement of surface energy. Surface energy is the property of a surface arising from unbalanced molecular forces at or near the surface, compared to those in the bulk material.

How surface energy test inks work – If a liquid is applied to the surface and its surface energy is higher than the surface energy of a material to which it is applied then the liquid tends to form droplets. If the surface energy of the liquid is lower than that of the surface to which it is applied it will spread out or “wet” the surface evenly.

Surface energy testing

By brushing surface energy test Inks of progressively increasing surface tension over a plasma treated surface, one can accurately ascertain the material surface energy, and therefore the improvement in wettability and bonding characteristics compared with an untreated surface.

Surface energy is normally measured in energy units called dynes/cm or mN/m. Individual surface energy test inks are supplied in 12ml bottles of varying surface tension from 12mN/m to 105mN/m, or as handy kits with fluids that have a selection of surface tension levels; 28 mN/m, 38, 48, 56, 64, 72 and 105 mN/m.


Portable Contact Angle Meter

surface test equipment - plasma products contact angle measurement

The PGx is a fully automated Portable Contact Angle Meter that measures surface wetting and absorption in-situ on virtually any size or shape of the surface.

With a footprint of only 90mm x 55mm and weighing just 400g, it is the smallest contact angle meter available, with features previously found only in larger laboratory instruments. The PGx enables direct surface testing of almost any 3D object without having to cut the sample to fit. Simply place the PGx Portable Contact Angle Meter on your sample or part and press a single button. The PGx automatically delivers a precisely calibrated drop onto the surface and the built-in camera captures a video sequence of the surface wetting at a rate of 80 frames per second. The results are displayed as a static contact angle or dynamic wetting as a function of time, providing detailed information about the liquid/substrate interaction in a truly portable instrument.

The PGX portable contact angle meter

The PGx Portable Contact Angle Measurement Meter is trusted in a wide range of industries and especially suited to the evaluation of samples both before and after plasma treatment, being fully compliant with official test methods ASTM D-724 and ASTM D-5946.

  • 0.2uL to 10uL droplet size
  • Touch down, impact and manual drop application modes
  • Built-in, automatic calibration
  • Automatic sampling in both Static and Dynamic modes
  • adhesion (glueing, bonding)
  • absorption
  • surface contamination (cleaning)
  • wettability (printing, painting, coating

Surface Silicone Contamination Test Kit

surface test equipment - henniker plasma silicone test kit

Silicone contamination of surfaces poses a real problem in many manufacturing steps. Silicones can be present due to mould release agents or simply from leeching from ‘clean’ packaging, resulting in poor adhesion and bonding characteristics.

Our surface silicone contamination test kit is a convenient method to determine the presence of silicones. Supplied in a handy case, the kit contains everything needed to perform a simple test for surface contamination by silicones.

The test kit contains:

  • Wash solvent
  • Mineral glass slides
  • Over-spray
  • Padded carry case
