The Theta Flow was designed with meticulous attention to detail and delivers a user-friendly experience while maintaining accuracy across experiments. Theta Flow’s design includes integrated sensors for commonly overlooked factors such as camera tilt angle, system levelness, temperature, and relative humidity which can all affect experimental reproducibility.
Theta Flow’s many high-end features work synergistically to ensure a faster workflow and consistently reproducible results—independent of day-to-day or operator-to-operator variation:
- Touchscreen to control automated components using context-sensitive sliders, streamlining and ensuring consistency in experimental setup
- Large 12 cm x 12 cm sample stage accommodates larger samples and allows for more measurements per sample
- Powerful 5-Megapixel camera with software controlled autofocus delivers superior image definition and sharp contrast for accurate, user-independent contact angle measurements

See Available Modules
The unique 3D Topography module takes wettability and adhesion analysis to a completely new level by measuring both contact angle and surface roughness of the sample in a single measurement.
The High Pressure Chamber is designed for wettability research within enhanced oil recovery and enables measurements at pressures up to 400 bars and temperatures up to 200°C.
A software controlled tilting cradle. Used for studying dynamic contact angles. Tilting range from 0 to 90° and tilting resolution 0.1°.
Software controlled drop size pulsing for interfacial rheology measurement of viscoelastic properties of interfacial layers at liquid-air or liquid-liquid interfaces.
Utilize automated picoliter-scale drop formation. Especially useful for inkjet applications and for measuring contact angle on very small sample areas.
