<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">Depending on the precision and reproducibility you need, you can also try building your own system with a light source, a stage, a droplet dispenser and a digital camera. The tricky part is the precise
deposition of a droplet and the precise measurement of the contact angle . You could buy a micrometer dispenser:</span><span lang="EN-US">
