The
OCA 15 is the budget-priced R&D instrument for automated video-based
contact angle metrology and drop shape analysis. It can be easily upgraded
to OCA20, OCA30, OCA40M or OCAH200 models with additional capabilities
and extended specs.
It features proprietary software-controlled measurement and analysis
of
-
Contact Lamella Method on any liquid including pastes and polymer
melts.
-
Static and dynamic contact angle according to the Sessile and Captive
Drop Methods as well as the analysis of the drop shape according to
the Pendant Drop Method.
-
Wetting behavior of solid surfaces.
-
Surface energy of solids surfaces and their components for Work of
Adhesion/calculation. Surface and interfacial tension through the
analysis of the Pendant Drop Shape Method.
The
OCA 15 consists of the basic instrument with the following technical
equipment:
- Dosing
bay for installation of single or multiple (max. 4) syringe units
including needle support with vertical and horizontal fine adjustments.
Alternatively, a direct dosing unit with one electronic syringe unit
is also available.
- Measuring
stage, adjustable in three axes for accurate sample positioning.
- Lens
mount with adjustable tilt.
- High-performance
six-fold power zoom lens with an integrated continuous fine focus.
- Video
system with adapter and CCD-camera.
- High-performance
video digitizing board (frame grabber) for PC.
- Halogen
lighting with continuously adjustable intensity without hysteresis
for a homogeneous back lighting.
- Power
supply with automatic voltage adjustment.
