Key Benefits

3 reasons to invest

Interfacial viscoelasticity with ease

Fully automatic measurements of interfacial viscosity and elasticity are user-independable and highly accurate due to automatic droplet creating and pulsation as well as due to high end imaging system.

Smarter rheology measurements

Automatic evaporation compensation keeps the droplet volume stable. Wide pulsation frequency range up to 10 Hz with reliable piezo technology. Sinusoidal, triangle, and square waveforms for wide possibilities. Temperature control option up to 250 C. 

Widen your possibilities

In addition to interfacial rheology, the same system is ready for surface tension, interfacial tension, contact angle and surface free energy measurements. Handle your current and future surface science needs at once.
