Drop Bubble Profile Analysis Tensiometer PAT-2

Economical Drop and Bubble profile Analysis Tensiometer for the measurement of Surface Tension and Interfacial tension of liquids, equipped with a manual dosing system.


The Profile Analysis Tensiometer PAT-2 is a simple instrument with modern software. Drop and bubble profile analysis belongs in the category of most modern methods to measure the surface tension and interfacial tension of liquids. Manual dosing system allows even simple dilational elasticity experiments.

Applications : surfactants, detergents, pharmaceutical, cosmetics, food, medicine and biology, ecology.

Surface and interfacial tension 1 to 1000 mN/m (dyn/cm)
Resolution 0.1 mN/m (dyn/cm)
Temperature 10 to 80ºC
Dimensions (WxLxH) 70x30x20 cm (28x12x8’’)
Weight 2 kg (5 lb)

The measurement is based on the analysis of the shape of pendent and sessile drops or buoyant and captive bubbles.
