Surface tension measurement - analysis by Goniometer

Your need: perform a Goniometer analysis

The Goniometer in a few words

The goniometer is a device for measuring surface tension and surface tension by contact angle.

The device deposits a drop of deionised water or other solvent with a predefined volume of a few µl on the surface of a material and then analyses the shape of the drop at a rate of 80 images per second.

Why perform a Goniometer analysis?

The dimensions of the droplet give information on the intermolecular forces and allow the calculation of a surface tension in mN/m.
The angle formed between the droplet and the material gives information on the hydrophilic character of the material studied. The smaller the angle measured, the more hydrophilic the material.
For certain applications such as gluing or printing, the absorption rate of a liquid on its substrate is a critical parameter.

analyses goniomètre

The dynamic measurement of the contact angle provides information on the spreading rate or absorption rate of the material under analysis. As with the static measurement, a drop is deposited on the surface of the material. The evolution of its contact angle is measured by acquiring an image every millisecond for up to 10 minutes.
