Contact angle measuring instrument OCA 200

surface energyfor liquidsmodular

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 expert model OCA 200 is the contact angle measuring instrument for microscopic and macroscopic structures. Thanks to the 10x zoom lens and the autofocus system, the OCA 200 is suitable for any sample size from the macroscopic silicon wafer to the microscopic metal struts of a coronary stent. Together with the PDDS picolitre dosing system, the OCA 200 allows the analysis of droplets with a minimum volume of up to 30 picolitres. Possible Measurements: - static contact angle - dynamic contact angle - analysis of interfacial and surface tension - analysis of surface energy - analysis of the viscoelastic modulus - analysis of the work of adhesion Features: - sample stage adjustable in all three spatial directions with precision electronic axes - video measuring system with high-performance camera with up to 3250 frames/s and USB 3 interface - ground-breaking 10x zoom lens - TP 50 control panel with touch screen and precision control wheel included - compatible with the nanolitre dosing system, which can dose drops with a minimum volume of 10 nanolitres - compatible with the PDDS picolitre dosing system - upgradeable with environmental chambers for measuring at temperatures ranging from -30 °C to 700 °C - upgradeable with the manual tilting table TBA 360 and the electronic tilting unit TBU 100 - upgradeable with the TVS TopView Video System
