OCA 25

The OCA 25 is the all-purpose measuring device for contact angle measurements and drop shape analysis.

The sample table of the OCA 25 is adjustable along all three directions in space via precision axes with hand wheels. Hence, a fast and exact manual positioning of the sample is always guaranteed, even when using high-performance temperature chambers like the electrical temperature control unit TEC 700U.

OCA 50 & OCA 50EC

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 OCA 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.
