DROPimage CA

DROPimage CA is our entry-level software solution. This program ships standard with our Model 190 CA Goniometer and can be upgraded to DROPimage Standard or Advanced for more demanding applications. The two primary tools in DROPimage CA are the Contact Angle Tool and the Calibration Command as outlined below. Additional menus are available for: options, saving and opening images, data export, video setup, zooming, and baseline setup. DROPimage CA uses the same algorithms, video control, and methodology employed in the more advanced versions of DROPimage, but lacks the more advanced tools.

Contact Angle Tool
The Contact Angle Tool characterizes the behavior of a liquid on a solid. When a liquid is placed in contact with a solid surface, the bare surface of the solid absorbs the vapor of the liquid until the volatility of the absorbed material is equal to that of the liquid. When equilibrium is established, there is a liquid-solid interface between the two phases. The tangent angle between solid and liquid is known as the contact angle. 

Calibration Command
When the instrument is shipped, the system is fully calibrated. However, if the lens assembly is readjusted to any degree or any change is made to the magnification system, the instrument is no longer calibrated. The Calibration command uses a ball with a precise diameter to calibrate the magnification of the camera, resulting in 100% accurate readings. The calibration can then be verified at any time using a calibration check utility. All ramé-hart systems ship with a proprietary floating calibration ball.

Contact angle describes the shape of a liquid droplet resting on a solid surface. The roughness of a surface improves the wettability for hydrophilic surfaces. hydrophobic surfaces. Young equation, which interrelates the contact angle and surface tensions of the liquid and solid phases. International Symposium on Contact Angle, Wettability and Adhesion. The angle of contact is the angle between the tangent to the periphery of the point of contact with the solid. Capillarity is an effect when liquid in a narrow vertical tube becomes elevated or depressed. When a liquid does not spread on a substrate (usually a solid), a contact. angle (θ) is formed which is defined as the angle. Contact angle measuring unit for characterization of hydrophobicity of film surfaces are used in controlling cleaning processes. A computer controlled contact angle analyzer makes it easy to measure static and dynamic contact angle, along with surface tension and surface energy. CONTACT ANGLE MEASUREMENT is a common method to obtain surface energies of materials. The measurement by itself is nothing novel; however, the relationship of contact angle to surface energetics requires a good deal of understanding. I have published several papers regarding various aspects of that relationship, especially related to polymers. Surface energy quantifies the disruption of chemical bonds that occurs when a surface is created. In the physics of solids, surfaces.
