DCAT - DYNAMIC CONTACT ANGLE TENSIOMETER
Instrument Name & Model: Dynamic contact angle (Dataphysic – DCAT21)
Special Features & Descriptions
The dynamic contact angle measuring instrument and tensiometer DCAT 21 is the multifunctional instrument for the weight-based measurement such as:
- Contact angle
- Surface and interfacial tension
- Critical micelle formation concentration
- Density
- Sedimentation penetration
- Adhesive force
- Surface pressure.
Main features of the DCAT 21 are as follows:
- high-precision electrodynamic compensation weighing system with automatic calibration
- Software controlled, motor-driven height positioning of the sample receptacles with variable speed
- Automatic coupling lock for the balance
- Illuminated sample chamber with inert gas or vapor inlet
- Versatile specimen holders for various samples, including fibre bundles, powders, film, cylinder and plate samples
- Du Noüy rings – for surface tension measurement of liquid
- Wilhelmy plates – for determination of surface tension (SFT) of a liquid, the interfacial tension (IFT) between two liquids, and the contact angle between a liquid and a solid
