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. Measurements: - static contact angle - dynamic contact angle - interfacial and surface tension - surface energy - viscoelastic modulus - work of adhesion
