The contact angle goniometer from Ossila is a simple plug and play tool which can be used to measure the contact angle between solid and liquids. 
The measurements give information on hydrophobicity of the surface and can be used to optimize wetting and wettability of e.g. photoresists on different surfaces. 

The tool is stored in a cubboard and require jsut few seconds to be mounted. The PC controlling the software is shared with tool #129 - IR microscope.
