interfacial tension testing

Tensiometer for surface tension measurement

Kruss universal tensiometer K20 for basic testing, quality control. Analyses surface tension and interfacial tension based on the wetting force acting on the measuring probe. Uses the ring and plate method.
Use and applications:
- determination of wetting agent efficiency
- checking surfactant content in solutions below the critical micellisation concentration (CMC)
- checking the tightness and cleanliness of tanks in the food industry
- measurement of interfacial tension in quality control and optimisation of emulsifiers
