PDDS Goniometer OCA25 – DataPhysics

A high-precision system for wettability analysis at the micro- and nanoscale, capable of generating micro-drops and accurately measuring liquid/solid interactions.

Applications

The PDDS OCA25 goniometer allows you to :

  • Characterize the affinity of a liquid with a surface (static contact angle)
  • Calculate the surface energy of a material
  • Quantify the wetting or repellent properties of a coating or surface treatment
  • Test the reproducibility and homogeneity of hydrophilic/hydrophobic treatments

Typical applications :
Coating development, quality control, formulation, printing, biomaterials, and microfluidics.

Available Measurement Types

  • Static contact angle (liquid/solid)
  • Surface energy calculation of solids
