The
DCAT 11 is used for the software-controlled measurement of
- Contact
angle of powders and fiber bundles and the adsorption behavior of
liquids on wettable materials according to the modified Washburn method
- Dynamic
contact angle and the surface energy of prismatic and cylindrical
samples according to the Wilhelmy method
- Static
surface and interfacial tension of liquids
- the
critical micelle formation concentration of surfactants (CMC) according
to the Wilhelmy Plate method, Lenard Frame method or the Du Noÿ
Ring method with automatic ring correction according to Huh &
Mason, Zuidema & Waters and Harkins & Jordan methods
- As
well as for fully automated reproducibility measurements.
The DCAT 11 consists of the basic instrument with the following technical
equipment:
- High-precision
electro-dynamically compensated weighing system with automatic calibrating
function
- Software-controlled
motorized height positioning of the sample vessel with variable speed
- Integrated
measuring and control electronics with digital thermometer
-
Graphical display for weighing data, temperature and other measuring
statuses
- Serial
RS 232C interface with PC connecting cable
- Illuminated
sample chamber with connection for inert gas
- Sample
vessels of borosilicate glass available with diameters 50,70,100 mm
- Pt100
temperature sensor for the installation in the temperature control
unit
- Du
Noÿ ring RG 11, made of platinum-iridium to DIN 53914
- Wilhelmy
plate PT 11, made of platinum-iridium to DIN 53914
| The
32-bit NT based software SCA 200 developed for Windows 2000/XP offers
by various expansion steps. The analyses according to different
methods were build-in the software |
 |
It
is prepared for the installation of a fluid circulation temperature
control unit with an integrated magnetic stirrer for mounting either
one of the sample vessels TV 50 / TV 70 / TV 100.
