The open design and convenient control keyboard operations make the Sigma 702 extremely easy to use. Results are displayed on a large integrated digital screen. The instrument comes equipped with data software and can be connected to an external computer for additional data storage and simple reporting.
- Stand alone (no external computer necessary)
- Surfactant surface tension
- Powder wettability and absorption
- Interfacial tension
- Critical micelle concentration (CMC)
- Dynamic contact angle
- Adhesion force
Surface Tension/Interfacial Tension Utilizing Du Noüy Ring, Wilhelmy plate or rod, record and analyze the forces exerted onto a probe or solid sample using a sensitive microbalance. The force seen by the balance can be converted into surface tension or interfacial tension when a platinum Du Noüy ring or Wilhelmy plate is used for drawing up the liquid in a meniscus.
