Description
SINGLE mode
• Concentration quickly controlled
• Fast and reliable for control tasks
• measures one value at defined parameters
AUTO mode
• convenient mode for R&D: measurement of dynamic surface tension depending on bubble lifetime (surface age)
• Automated scan of surfactant dynamics
• Investigation of the kinetics of surfactants
• Characterisation of wetting behaviour
ONLINE mode
• Continuous measurement at bubble lifetime
• Analysis of temperature influence
• Investigation of ageing behaviour
• Evaluation of sample stability
