Bubble Pressure TensioMeter

The bubble pressure Tensiometer generates bubbles through a capillary tube immersed in a liquid and measures the maximum pressure during bubble formation, which is proportional to the surface tension of the liquid. It is used to detect the surface tension of liquids and is suitable for quality control in industries such as coatings and inks.
Selection
When selecting, consider that the measurement range covers the sample tension values, the accuracy meets the testing requirements, the operation is user-friendly, the instrument materials are corrosion-resistant, the data output method is compatible with the existing system, and the maintenance costs are reasonable.

Surface Tensiometer Evaluates the Wetting and Spreading Properties of Resin Liquids
This article introduces how to use a surface tensiometer to evaluate the wetting and spreading performance of resin liquids. Wetting and spreading affect the adhesion and appearance of products such as coatings and adhesives, and the process can be described by Young's equation and the spreading coefficient.
Determination of Static Surface Tension of Color Coatings Using the Platinum Plate Method with a Surface Tensiometer
This article introduces the method of measuring the static surface tension of colored paints using the platinum plate method. It explains the principle, which involves calculating the surface tension by measuring the force when the platinum plate is lifted from the liquid surface.
Surface Tensiometer: Interpreting the Invisible Forces on Liquid Surfaces
Surface tension is the contractile force generated by the uneven forces acting on molecules at the liquid surface, influencing phenomena such as droplet formation and capillarity. Surface tension meters measure this force using techniques like the Wilhelmy plate method, the platinum ring method, or the pendant drop method. Their core components include force sensors, sample stages, and data processing systems.
Surface Tensiometer vs. Contact Angle Goniometer: Which One to Choose for Wetting Studies?
Surface tension meters primarily measure the surface tension of liquids and are suitable for analyzing the properties of liquids themselves, such as purity or the effects of additives. Contact angle meters, on the other hand, evaluate the wettability of solids by analyzing the contour of liquid droplets on solid surfaces, and are commonly used in surface treatment or coating research.
Tips for Cleaning and Maintaining the Platinum Plate/Ring of a Surface Tensiometer
In the field of laboratory testing, the measurement accuracy of a surface tensiometer largely depends on the cleanliness and intact condition of its key components—the platinum plate or platinum ring. This article explains how to maintain them.
How does a surface tensiometer determine the success or failure of printing quality?
Surface tension is a critical factor affecting printing quality, as it determines the wetting and adhesion of ink on materials such as paper and plastic. Accurate measurement and control of the surface tension of relevant liquids using a surface tensiometer are prerequisites for ensuring printing quality.
