PGX+ Contact Angle Goniometer

PGX Contact Angle Goniometer



The PGX+ Goniometer is a portable, video-based goniometer designed for quality control applications, to provide dynamic and static contact angle measurements, surface tension and surface energy. Itmeasures contact angle (dynamic and static), surface tension, and surface energy. The PGX+ Goniometer makes a drop in µl according to the size that is set. The drop is automatically released and 80 images per second are made.





  • Complies with test method Tappi T458, ASTM D 724, ASTM D 5946
  • Easy to handle, small sized
  • Full control of the test
  • No sample preparation
  • Registration with 80 frames/second
  • Measure Static and Dynamic Contact Angle, Surface "free" energy, Surface Tension
  • Multiple test fluids possible
  • Runs on every Windows computer
  • Power from USB connection
  • Software gives an overview, and allows pictures and results to be stored and analyzed
  • Used for paper & board, solar cell panels, windshield, metal cylinders ad similar surfaces
  • Dosing Unit - The optional Dosing Unit enables you to use fluids with higher viscosity. Because of the more precise dosing this option is also more consistent.
  • For most tests deionized water is used, however using other liquids is also possible. Contact us for use on other liquids.

PGX+ Goniometer Dosing Unit

Dosing Unit Kit Dosing Unit Kit
The PGX+ Goniometer Dosing Unit is a testing instrument used to determine the interaction between a liquid droplet and a surface. Liquid droplets can be applied by means of a manual dispenser (syringe) or in some of the models an integrated miniature pump. When tacky liquids or many different liquids are used, it is necessary to clean or replace the liquid system to avoid contamination

  • Small and portable size
  • Affordable and versatile
  • Programmable droplet size and cyclic pump sequences
  • Automatic testing of advancing/receding contact angles
  • The new concept ‘Disposable Liquid System’ is an attractive alternative to tedious cleaning and replacement of expensive parts
  • The complete liquid system consists of a one mL syringe, a dispensing tip and a PTFE tubing. This standard syringe produces more than two hundred liquid droplets of four microlitres and when the syringe is emptied or not required any more, the entire liquid system is disposed of. A new syringe is then filled with the new test liquid, a new dispensing tip with tubing is attached and the syringe is put intoi the PG Dosing Unit.
  • The most comon use is to set the pump to a preset droplet volume and pump out a new droplet for each new test position. The PG Dosing Unit can also be programmed for sophisticated analysis of the “wetting hysteresis” using the advancing/receding contact angles to characterize the surface properties.
