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
