SCIENTIFIC Solutions has released the new Sita Dynotester in Australia and New Zealand for measuring dynamic surface tension.
The Dynotester monitors dynamic surface tension at three pre-settable bubble lifetimes between 15ms and 15s. This means most high shear processes can be monitored at minimal cost.
The Dynotester, which is manufactured in Germany by Sita Messtechnik GmbH, has temperature compensation built in and automatically controls the bubble lifetime. The control of the instrument is directly over bubble lifetime, so immersion depth is much less critical than the old surface age control technique.
Sita Messtechnik are leading manufacturers of easy and safe to handle bubble pressure dynamic surface tension meters for the most convenient use in both R&D and QC applications.
The Sita DynoTester is a small and precise hand-held dynamic surface tensiometer for quick quality control or in field users. With a bubble lifetime 15ms - 15s, it is suitable for a broad range of applications. One keystroke gives you the surface tension value of your sample
The Sita Pro Line t60 is a reliable laboratory or on-line dynamic surface tensiometer. It can be used at the production line in discontinuous or continuous measurement tasks.
A bubble lifetime 30ms - 60s covers most typical wetting agent or surfactant concentrations in cleaning or galvanic processes as well as for formulation of inks, agrochemicals and emulsion systems. The instrument can focus on static to very dynamic static surface tension measurements with equal precision.
Endless continuous measurements with an optional flow-through system are available for online applications. Automatic measurement of dynamic surface tension curves through the whole bubble lifetime range is possible in the basic instrument.
All measured values from any Sita instrument can be directly compared because of the use of common measurement technology and the automatic control of bubble lifetime. Laboratory guidelines developed on the t60 can be directly transferred to the Dynotester for in-field quality or process control.
