Fully-equipped Research grade video-based

The OCA 30 for the automatic measurement of the wetting behavior of solids, as well as for series tests and systematic analysis. The OCA 30 enables the reduction of subjective factors and time involved for contact angle measurements in research, quality and production inspection.

For the software-controlled measurement and analysis of

• Static and dynamic contact angle according to the Sessile and Captive Drop method
• Drop shape analysis according to the Pendant Drop method
• Wetting behavior on various solid surfaces
• Surface free energy of solids and their components
• Surface and interfacial tension out of the analysis of the drop shape
  

The OCA 30 consists of the basic instrument with the following technical equipment:

• Dosing bay for installation of the optional manual syringe units and single or multiple (max. 4) needle support with a vertical and horizontal fine adjustment
• Measuring stage software controlled motorized adjustable in Y- and Z- axis adjustable for accurate sample positioning and drop pick up from the dosing needle, in X-axis manual adjustable
• Lens mount with adjustable tilt
• High-performance power zoom lens with an integrated continuous fine focus
• High-speed video system with adapter and CCD-camera
• High-performance video digitizing board (frame grabber) for the PC
• Halogen lighting with continuously adjustable intensity without hysteresis for a homogeneous back lighting
• Control and measuring electronics with built-in digital temperature display and serial RS 232C interface
• Power supply with automatic voltage adjustment

The 32-bit modular Windows NT based software SCA developed for Windows 2000/XP offers by various expansion steps. The analyses according to different methods were build-in the software.
