Tensiometer for surface and interfacial tension measurement
DIN EN 14210/14370, ASTMD 971 | TD 3
LAUDA DR. R. WOBSER GMBH & CO. KG
The ring/plate method of measuring the surface and interfacial tension of liquids is an established method with future potential: the increasing demand for surface active additives and proof of these in quality control requires fully automated and user-friendly equipment. As a stand-alone device, the compact, fully automated TD 3 ring/plate tensiometer with LAUDA Command remote control offers everything that is needed, both in the laboratory environment and for use on-site.
At the touch of a button, surface and interfacial tension can be measured easily, calculated precisely and reproducibly, printed, saved and optionally transferred to a computer.
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.
