DSA High Temperature

Get deep insights into the thermal behavior of materials

Our Drop Shape Analyzer – DSA High Temperature 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 solids 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.

Wetting analysis using precise contact angle measurement

The instrument optically determines the contact angle between a liquid and a solid as a direct measure of wetting. It is equipped with a high-resolution CCD 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 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 and desired temperature range, the setup of the instrument is optimized for analyses at temperatures up to 1600, 1800, or even 2000 °C.

Measurements can be carried out in oxidizing or reducing atmosphere, under inert gas or in vacuum. This makes it possible to simulate various industrial high temperature processes or to carry out comprehensive material research, such as metallurgical studies.

Optimize your high-temperature process

The hotter process conditions are, the more reactive are the materials involved. This can be desired when improving the stability of the end product, but also unwanted when chemical interactions affect quality or the service life of furnaces. Analyses with the Drop Shape Analyzer – DSA High Temperature provide you with a deep understanding of thermal behavior and support you in improving your process.
