Lauda Ring/Plate Tensiometer TD3

Product Details

For standard-compliant measurements

LAUDA TD 3, the successor to TD 2, comes with a new design and new technical features, some of which are unique. As such, e.g. the world’s smallest thermostat, the LAUDA PTT Peltier thermostating unit, is easy to insert into the device. The temperature of the measuring samples can be set from 5 to 80 °C extremely quickly, conveniently and with the smallest space requirement. The TD 3 determines the interfacial/surface properties of organic and inorganic liquids (liquid/liquid or liquid/gaseous), dispersions, emulsions including for the development of surface active substances such as surfactants and emulsifiers and as evidence of these in sewage and bodies of water.
