The DVA-1 Drop Volume Tensiometer allows measurement of surface and interfacial tension of liquids, dynamic interfacial tensions in a time range of less than 1 second, up to several minutes. The instrument is controlled via a PC or laptop. The filling procedure is automatic from a reservoir and the temperature measuring cell is controlled. The effect of viscosity is corrected for short drop times.
Applications: surfactants, ink jet, coating, foam and emulsion, detergents, pharmaceutical, cosmetics, food, medicine and biology, ecology.
