OCA
5/10
Manual
optical contact angle measuring device
-upgradeable
to any higher level device-
For measurement of
-
Static and
dynamic contact angle according to the Sessile and Captive
Drop method
-
Wetting behavior
on solid surfaces
-
Surface free
energy of solids and their components
The OCA 5 consists
of the basic instrument with the following technical equipment:
-
Dosing bay
for installation of manual syringe units (max. 4) and the single
or multiple (max. 4) needle support with a vertical and horizontal
fine adjustment, alternative a direct dosing unit with a manual
syringe unit
-
Measuring stage,
adjustable in three axis for accurate sample positioning
-
Lens mount
with adjustable tilt
-
High-performance
six-fold power zoom lens with an integrated continuous fine
focus
-
Goniometer
eyepiece with diopter adjustment
-
Halogen lighting
with continuously adjustable intensity without hysteretses for
a homogeneous back lighting
-
Power
supply with automatic voltage adjustment
The 32-bit "Windows NT based"
software SCA 10 developed for Windows 2000/XP offers:
The calculation of the surface
free energy of solids and their components out of the measured
contact angles with up to four different test liquids
The analyses according to different
methods (Zisman, OWRK, Fokes, FOCG, Wu, Schulz, etc.) were build-in
the software.
