Stability analysis of temperature-sensitive cutting fluids using the MultiScan MS 20
The DataPhysics MultiScan MS 20 stability analysis system provides a simple and reliable method to observe temperature-dependent changes in cutting fluid emulsions and analyze its thermal stability. Notably, the technique has internal heating device and respective temperature controllers, so that it can be used to develop and optimize the product at specific temperatures.

Stability study of a commercial protein shake using the DataPhysics MultiScan 20 stability analysis system
The stability of a liquid protein shake sample was tested using the MultiScan 20 stability analysis system. By analysing the transmission and backscattering behaviour of the dispersion, unstable components were detected and various destabilisation mechanisms could be distinguished within a very short period of time.

Stability study of a pesticide formulation using the DataPhysics MultiScan 20 stability analysis system
The stability of a liquid pesticide formulation sample was tested using the MultiScan 20 stability analysis system. By analysing the time-dependent transmission and backscattering behaviour of the dispersion, unstable components were detected and various destabilisation mechanisms could be distinguished within a short period of time.

Stability study of battery coating slurries using the dispersion stability analysis system MultiScan MS 20
Analysing the time-dependent and position-dependent transmission and backscattering intensity of different slurries, unstable slurry formulations could be identified within a short period of time which is valuable information in the development and optimisation of battery slurries.

Measuring contact angles on leaves at different relative humidity using DataPhysics HGC
The influence of relative air humidity on the wettability of plant leaf surfaces can be studied with a combination of our humidity generator HGC and optical contact angle measuring device OCA. The following note uses Miscanthus leaves as an example to present this technique.

Determining the surface energy of powders via washburn method
In this application note, the wettability of silica powder with various wetting liquids is assessed using a tensiometer of the DCAT series by DataPhysics Instruments and its corresponding software.

Measuring the surface tension of different molten granules using DataPhysics DCAT series
The tensiometer of the DCAT series with an electrical temperature control unit from DataPhysics Instruments is able to fast and easily determine the surface tension of molten granules in a temperature range of 80-150°C.

Measuring imaginary dynamic contact angles on dental implants using DataPhysics DCAT series
The tensiometers of the DCAT series with their dedicated software are able to determine imaginary contact angles reliably and reproducibly. This is a precious extension of the dynamic contact angle measurement method as it opens up the possibility to easily study hyperhydrophilic materials and, notably, to quantitatively distinguish the results also in cases where conventional methods always yield contact angles of 0°.

Measuring interfacial tension of insulating liquids against water using the Du Noüy ring method according to ASTM D971
The ASTM D971 is a widely used standard method to examine the quality of insulating oil. Here, the application of ASTM D971 is presented using a tensiometer of the DCAT series from DataPhysics Instruments.

Effectiveness of surface treatment techniques for dental implants using imaginary dynamic contact angle measurements
To study ultra-hydrophilic surfaces, imaginary contact angle measurements have evolved into a powerful technique. Tensiometers of the DCAT series are the only measuring systems so far which feature a reliable and reproducible imaginary contact angle determination in their software. This method is presented on samples of UV and plasma treated dental implants.
