Model OCA 200 -Expert Contact Angle Meter

SHARE
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, it is suitable for any sample size from the macroscopic silicon wafer to the microscopic metal struts of a coronary stent. Together with the FDDS FlexDrop dosing system, the OCA 200 allows the analysis of droplets with a minimum volume of 25 picolitres.
