Description
The OCA 50 is the fully automatic measuring device for the time-saving analysis of the wettability of solid surfaces and the determination of the surface energy of solids.
The sample table of the OCA 50 can be positioned along all three directions in space via electronic high-performance axes, with both extraordinary speed and highest precision. Combined with an electronic multiple direct dosing system DDE/x and up to four electronic syringe modules ESr-N the determination of surface parameters can be automated completely.
The automation of measurements succeeds easier than ever before thanks to the intuitive automation dialogue of the software and its visual drop positioning system. Hence it is possible to determine, for example, the surface energy with four test liquids at different position of even large samples without any manual user intervention. This facilitates a complete and automated sample mapping.
In order to map silicon wafers, electronic turn tables with vacuum fixation are available. They allow to access any position for contact angle measurements, even on 12″ wafers.
In any case, the 6.5-fold zoom lens and the high-performance camera with USB 3 interface ensure optimal images of the deposited drops.
Even smaller structures can be analyzed using the picolitre dosing system PDDS which can dose down to 30 picolitre small droplets. These allow contact angle measurement, for example, on the individual wires of the mesh structure of a coronary stent or on single fibers. Main features:
- Sample table adjustable in all three axis via software
- high performance 6.5-fold zoom lens
- integrated continuous fine focus, and adjustable observation angle
- video measuring system with high-performance camera using USB 3 interface
- LED-lighting with manual and software controlled intensity including automatic temperature drift compensation
- TP 50 control panel with touch screen and precision control wheel.
