Surface Tension Meters — Surface Analysis Instruments
Surfactant, ink, coating, lubricant and oil laboratories rely on surface and interfacial tension to control wetting, foaming and emulsion stability. Our tensiometers cover the Du Noüy ring, the Wilhelmy plate, optical pendant drop, maximum bubble pressure for fast-forming surfaces and spinning drop for ultra-low interfacial values. Measurements can be carried out according to ASTM D1331, ASTM D971, ISO 304 or OECD 115.
