DCAT 11
The DCAT 11 is the standard instrument for applications which require a ten times improved measurement precision compared to the DCAT 11EC and an increased travel speed range and travel resolution for the sample table. For example the analysis of single fibres where a greater travel speed range and a better travel resolution is necessary.

DCAT 11EC
The&nbsp;dynamic contact angle&nbsp;measuring instrument and&nbsp;tensiometer&nbsp;DCAT&nbsp;11EC is the budget-priced instrument for the weight-based measurement of contact angle, surface and interfacial tension, critical micelle formation concentration, density, sedimentation and penetration rate, plus penetration resistance.

DCAT 21
The DCAT 21 is the all-purpose&nbsp;dynamic contact angle&nbsp;measuring instrument andtensiometer. It offers a 30 mm longer travel for the sample stage than the DCAT 11 and allows therefore the use of the optional electrical temperature control unit TEC 250/DCAT.

Dynamic contact angle measuring instruments and tensiometers DCAT
In many diverse engineering applications the ability of liquids to wet solids affects the quality of the finished products and the integrity/reproducibility of the manufacturing processes. Some important examples of this are the production and application of paints and varnishes, the development and the optimisation of composite materials, the use of adhesives and selection of solvents for engineering materials, and the biocompatibility of medical implants. Reliable analytical data is provided via the precise evaluation of static and dynamic contact angles, the surface free energy of solids and the surface and interfacial tension of liquids. Last but not least, the recent, rapid, advance­ments in nanotechnology and biotechno­logy have been possible, only, through an exact know­ledge of wetting processes in the sub-microscopic level.
