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 accurately 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. Sample temperature is measured. 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.
