With this instrument you can measure:
Contact angle on flat, curved and non-horizontal surfaces.
Surface Energy (resp. Surface Tension) of substrate (resp. liquid) to calculate polar or AB, dispersive or LW, monopolar acid and monopolar basic component
Contact angle and surface energy at different level of humidities and control fo the saturation of the vapour The DGD-DI is a powerful modular and sturdy scientific instrument dedicated to surface chemistry studies. Everything has been thought to make the study of the scientist easy without neglecting the cost of the space in a lab. Moreover, the software is very easy to use Different sizes and temperature controlled chambers are available depending on the application. The liquid inside of the syringe can be regulated in temperature too. In case of the use with a humidity generator , the chamber will be small 50 mm x 70 mm to speed up the humidity equilibrium. The value of the humidity and temperature is displayed on the results table for a correlation between contact angle and humidity. A optional manual Y-axis table is supplied with this chamber to move the sample forward and backward
