TD 3 Ring/Plate Tensiometer

TD 3 Ring/Plate Tensiometer

With the LAUDA TD 3, the measurement samples in the range from 5 to 80 °C can be thermostated extremely quickly and conveniently with the smallest of space requirements. The tensiometer serves to determine the surface/interfacial properties of organic and inorganic liquids (liquid/liquid or liquid/gas), dispersions, and emulsions (among others, for developing surface active substances like surfactants and emulsifiers) as well as for confirming their presence in waste water and other water samples.
