[labnetwork] contact angle goniometer

[Leif Johansen]

Hello Kevin,

We have an automated DSA-100 Drop Shape Analyzer from Krüss in Germany. It is a very nice tool, but it can hardly be classified as reasonably-priced.
Kruss also has less expensive products, like the DSA-25. https://www.kruss-scientific.com/products/drop-shape/dsa25/drop-shape-analyzer-dsa25/

I have previously worked with a manual Tantec contact angle meter. As far as I know, they are not that expensive. https://cheminstruments.com/contact-angle-meter.html

Hustech also sell contact angle goniometers, but I know very little of these: http://www.hustech.co.kr/?portfolio=rame-hart-model-400-goniometer-with-wafer-support

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: https://www.coleparmer.co.uk/i/gilmont-gs-1200-a-micrometer-burette-style-dispenser-1-ea/0784600 . EPFL offers free drop shape analysis software on their homepage: http://bigwww.epfl.ch/demo/dropanalysis/

Best regards,
Leif

Does anyone have advice for a nice automated reasonably-priced contact angle goniometer?

Thanks in advance,
