Drop Pressure Analyzer DPA


A completely new instrument has been developed for measurements of the dynamic interfacial tensions of solutions in the range of about 50 ms to long times.

Modul Applications

- dynamic interfacial tensions of surfactant solutions
- available time range from less than 50 ms to minutes and hours
- measures also surface tension of liquids
- measures interfacial tension between two liquids of the same density
- dilational rheology with slow deformations
