OCA 25

Optical Contact Angle – 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 a precision axis and guided by hand wheels. The OCA 25 offers fast and exact manual positioning of the sample, even when using high-performance temperature chambers like the electrical temperature control unit TEC 700.

Analysis of even the fastest processes is possible recording up to 3250 frames/s using the 6.5-fold zoom lens and the high-performance camera with USB 3 interface. Hence, contact angles on adsorbing surfaces like tissues or powders can be measured reliably.

For dosing liquids, the manual single and double direct dosing systems (SD-DM and DD-DM can be used as well as the electronic multiple direct dosing systems DDE/x. The latter can electronically position one to four electronic syringe modules ESr-N. Additionally, a nanolitre dosing system can also be used to generate extra small liquid drops. Even these are no challenge for the OCA 25 due to its high-resolution optics.
