OPTICAL CONTACT ANGLE

The Contact Angle Measuring Device (also known as Goniometer) is equipment based on optical measurement to determine the contact angle between the solid surface and the falling liquid drop. The calculated data is the contact angle, which helps to examine the wetting characteristics of solids to liquids.
By implementing contact angles measurement of multiple test liquids, we can find the free energy on the surface of the solid and the adhesion property of those different liquids can be further studied with the software analysis support.
The contact angle measurement method has become prevalent in many different industries and fields of research, such as surface treatments and finishes, surface coatings, detergents, chemical dispersants as well as paints and varnishes. Some typical applications include:
  • Static or dynamic mode of contact angle determination
  • Sessile drop method for wettability study of solid
  • Surface energy measurement of solids
  • Pendant drop method in optical examination of surface and interface tension
  • The fully automatic sample mapping
Available in: Vietnam, Singapore, Malaysia, Indonesia, and Thailand
