Bubble Tensiometer BPA-800P is a standalone instrument able to deliver highly accurate and reproducible dynamic surface tension measurements in under 6 minutes. Dynamic surface tension measurements provide information on the wetting properties of the liquid. This data is useful for controlling and developing the surface active agents for a number of processes such as printing, spraying, cleaning and coating. BPA-800P also enables direct and precise determination of bubble lifetime characteristics, providing insights on diffusion and absorption coefficient of surfactants. With unknown liquid samples, the BPA-800P is able to accuray correct for and estimate sample viscosity and gravitational deformation of bubble shape. BPA-800P has the ability 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 friendly instrument. The liquid surface is automatically detected and the capillary is lowered to the appropriate level. Data is stored in integrated memory, and can be uploaded onto a computer. The included software also enables operating the BPA-800P with a computer as well as performing data analysis. Results can be presented as a function of measurement time and effective adsorption time. Portability and battery operation make the instrument extremely useful in industrial and environmental applications.
