Bubble Method TensioMeter

The bubble pressure Tensiometer continuously generates bubbles at the end of a capillary tube immersed in a liquid, measuring the maximum pressure required to form the bubbles, which is proportional to the surface tension of the liquid. It is used to determine the surface tension of liquids, monitor wettability and formulation stability in the coatings and inks industry, and evaluate coating spreading effects in printing and papermaking.
Selection
When selecting a bubble pressure Tensiometer, it is essential to consider the measurement range to cover the sample's surface tension values, ensure the accuracy meets the detection requirements, verify that the sample-compatible materials are corrosion-resistant, confirm the operation interface is intuitive and user-friendly, ensure temperature control functionality is available to adapt to the experimental environment, and check that the data output format matches recording needs.
