Equipment Description

This instrument is used to evaluate the favorable or unfavorable interactions between a material and a liquid by measuring the contact angle between the material surface and a droplet of the liquid deposited on it. Measurements can be performed under static or dynamic conditions, as the instrument is equipped with a camera capable of capturing both photographs and videos. It can also be used to study liquid absorption and adhesion on a surface. The instrument is equipped with powerful image capture and analysis software. It is operated in a cleanroom to minimize interference.
