Goniometer (ramé-hart™ Model 200) for measuring contact angle and surface energy on flat surfaces. Includes a manual Tilting Base for measuring advancing and receding contact angles. Also includes an environmental fixture for measuring liquid/liquid interactions; the fixture is primarily used for captive bubble analysis of hydrogels in solution with air drops released from an inverted needle. The updated DropImagePro software from ramé-hart™ allows quantification of contact angle, surface tension, and surface energy.
