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 measuredcontact 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. |
