Contact angle measuring instrument OCA 25

cameraindustrialUSB

The optical contact angle meters of the OCA series are high-precision measuring systems for the characterisation of interfaces and surfaces. They combine high-resolution optics, pinpoint liquid dosing and precise sample positioning to create powerful, reliable measuring systems. The OCA 25 standard model is the all-purpose system for contact angle measurements and drop shape analysis. The high-performance camera makes it possible to measure contact angles even on adsorbent surfaces such as tissues or powders. Possible Measurements: - static contact angle - dynamic contact angle - analysis of interfacial and surface tension with dispersive and polar parts - analysis of surface energy with dispersive and polar parts - analysis of the viscoelastic modulus - analysis of the work of adhesion Features of the OCA 25 contact angle meter: - sample table manually adjustable in all three directions with high-precision mechanics - high-performance camera with up to 3250 frames/s and USB 3 interface - fast lens with 6,5-fold zoom - stepless manual focus and manually adjustable observation angle - compatible with the nanolitre dosing system, which can dose drops with a minimum volume of 10 nanolitres - upgradeable with different environmental chambers for measuring at temperatures ranging from -30 °C to 700 °C - upgradeable with the TVS TopView Video System, which allows the measurement of contact angles in indentations - upgradeable with the manual tilting table TBA 360 and the electronic tilting unit TBU 100 - upgradeable with a humidity generator of the HGC series from DataPhysics Instruments
