Optical tensiometer Theta Pulsating Drop

for angle measurementfor interfacial rheologyfor surface and interfacial tension measurement

Optical tensiometer especially suitable for interfacial rheology with the pulsating drop method. Overview What you can measure Interfacial dilatational rheology Pulsating drop method Surface- and interfacial tension Pendant drop and reverse pendant drop methods Static contact angle Sessile drop, captive bubble, and meniscus methods Surface free energy Sessile drop, captive bubble, and meniscus methods Dynamic contact angle Dynamic contact angle, advancing and receding contact angle, contact angle hysteresis, and roll-off angle Roughness-corrected contact angle and 3D surface roughness Fringe projection phase shifting method 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.
