Goniometer

Goniometer

The LRCCP has extended its range of devices with the purchase of a Digidrop MCAT goniometer, equipped with a high resolution USB camera and a video measuring optics (magnification x 20), which produces photos and sequences video of deposited liquids drops. It is equipped with Visiodrop software with advanced functions.

This modular instrument allows accurate and reproducible measurement (± 0.1° on reference drops) of :

  • Contact angles (from 0 to 180 °) on flat, non horizontal and curved surfaces at different humidity levels
  • Surface energies (liquid-solid interfacial tensions), with determination of the polar and dispersive components
  • Surface tension of liquids (from 0.5 to 100 mN/m)
  • Degreasing or surfactant efficiency

The size of a standard sample is 60*60 mm.
