Drop Shape Analyzer
Analyzing wetting and material deformation at up to 2000 °C
- Data sheet
The DSAHT Drop Shape Analyzer goes to the extreme when it comes to wetting and deformation analysis of melts and combustion residues. With temperatures up to 2000 °C in a various range of atmospheric conditions, the instrument analyzes melting substances and helps to understand the interactions that occur when melts come into contact with solid material. This knowledge supports you in optimizing combustion, firing, or coating processes in order to create stable end products, save energy during the process, or prolong the service life of your furnaces.
Measuring adhesion and wetting of metal slags in smelting plants
Detecting reactions between the glass and refractory bricks in glass production

Investigating the changes of the green body depending on temperature and time in ceramics production
Contact angle of a drop on a solid surface
Surface tension (calculated from the curvature of a sessile drop)
Temperature in close vicinity to the sample
Wetting analysis using precise contact angle measurement
The DSAHT optically determines the contact angle between a liquid and a solid as a direct measure of wetting. Moreover, the surface tension of the hot liquid can be calculated from the curvature of the drop.
The instrument is equipped with a high-resolution camera, which records the sample while being heated up. With special filters that shield the light emitted by glowing materials, a clear shadow image is achieved, ensuring precise contact angle measurement.
Loading the furnace with the sample is a matter of seconds thanks to the easy handling of the sample holder. Due to the contactless nature of video analysis with no mechanical stress applied, the shape of the sample only depends on chemo-physical alterations with respect to time and temperature, which are both assigned to each camera image. The powerful image analysis of the ADVANCE software documents exactly what happens with your sample when heated up.
Accurate heating and versatile instrument configurations
Thanks to precise and stable target temperatures as well as accurate control of temperature ramps, highly repeatable measurements are a matter of course. Depending on the task, the setup of the instrument is optimized for analyses at different temperatures and atmospheres:
|DSAHT2000||Up to 2000 °C||Inert or reducing||
|DSAHT1800||Up to 1800 °C||Inert, oxidizing, or reducing||Vacuum down to 10-4 bar|
|DSAHT1600||Up to 1600 °C||Oxidizing or reducing||
This versatility makes it possible to simulate various industrial high temperature processes or to carry out comprehensive material research, such as metallurgical studies.
