Analyzing phase interactions and transitions at high pressures
The DSA100HP40 performs precise measurements of contact angle as well as surface tension and interfacial tension at pressures of up to 40 bar and temperatures of up to 200 °C. The main focus lies in chemical processes under pressure in which phase interactions and transitions as well as solid-liquid wetting must be investigated and optimized. The DSA100HP40 combines our expertise in the field of optical drop shape analysis and the know-how of our partner EUROTECHNICA in high pressure applications.
