Model OCA15 EC -Entry-level Contact Angle Meter

SHARE
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 measuring systems. The entry-level model OCA 15EC enables basic contact angle measurements and drop shape analyses. Thanks to the modular construction, even this entry-level model can be fitted with many accessories.
