Drop Volume Tensiometer, TVT 2
Drop-Volume tensiometer for dynamic surface and interfacial tension
- Precise measurement drop by drop
- Dynamic and static measurement mode
- Robust and precise design with a position accuracy in the micro-meter range
- Easy to use software
- PLL control of syringe speed
- Various syringe sizes (from 250µl to 5ml)
- Different needle diameters
- Reverse measurement needles
- Automatic adaption of light sensor sensitivity
- Minimizes contact with volatile/toxic samples
Applications
- Dynamic interfacial tension of surfactants, oils and highly viscous liquids
- Time-dependent surface tension measurement
- Aging effects on insulating oils (transformer oils)
- Absorption kinetics of surfactants
- Surface age dependent characterization of emulsifiers
- Surface age determination ranging from one second to several hours
- Absorption behavior of amphiphile molecules
- Characterization of inks
