|| Different lenses and cameras for every possible application

|| Optional revolutionary features such as the double view module for simultaneous top and side view and measurements on a single drop

|| Extremely versatile software package Surface.Meter included

Accessories:

|| Drop volume tensiometer module for surface/interfacial tension measurement based on drop volume determination

|| CMC module for fully automatic determination of both equilibrium and dynamic critical micelle concentration(CMC) of surfactants based on pendant drop method

|| Surface/interfacial rheology module based on Oscillating/Expanding Drop (OED) method

|| Fully automatic processs IFT monitoring system

|| Top-View drop analysis module, for determination of contact angle based on Top-View method, or with both Top-View and Side-View methods simultaneously

|| Full set of syringe & needle options are available

|| Automatic Tilting Stage:0 – 360° for studying advanced/receding contact angle, sliding/roll-off angle, sliding speed etc.

|| Rotating Force Balance (RFB) for studying retention force uo to 40g

|| Module for working with powder/porous samples: wettability, adsorption and contact angle measurement of powder/porous samples
