Bubble Tensiometer BPA-800P is a standalone instrument able to deliverhighly accurate and reproducible dynamic surface tension measurements in under6 minutes. Dynamic surface tension measurements provide information on thewetting properties of the liquid. This data is useful for controlling anddeveloping the surface active agents for a number of processes such asprinting, spraying, cleaning and coating. BPA-800P also enables direct andprecise determination of bubble lifetime characteristics, providing insights ondiffusion and absorption coefficient of surfactants. With unknown liquidsamples, the BPA-800P is able to accurately correct for and estimate sampleviscosity and gravitational deformation of bubble shape. BPA-800P has theability to handle extremely short as well as sufficiently long measuring times(patented technology).

The high level of automation and simplicity make BPA-800P a user friendlyinstrument. The liquid surface is automatically detected and the capillary islowered to the appropriate level. Data is stored in integrated memory, and canbe uploaded onto a computer. The included software also enables operating theBPA-800P with a computer as well as performing data analysis. Results can bepresented as a function of measurement time and effective adsorption time.Portability and battery operation make the instrument extremely useful inindustrial and environmental applications.
