BSI is also a distributor of Video Contact Angle Measurement equipment. VCA Systems combine precision optics, high definition camera, computerized image processing and specially designed software to perform contact angle analysis. Because of the user-friendly software, these systems require minimal training and interaction. Each unit can be customized with software and hardware accessories to meet individual measurement requirements. Technology Contact angle measurement is a simple to adopt method for surface analysis related to surface energy and surface tension.
Contact angle describes the shape of a liquid drop resting on a solid surface.
By drawing a tangent line from the drop shape to the touch of the solid surface, contact angle is defined as the angle between the tangent line and the solid surface. The measurement provides information to study the bonding energy of the solid surface and surface tension of the liquid droplet. Because of the simplicity in technique and measurement, it has been broadly accepted in various research environment and industries for material surface analysis related to wetting, adhesion and absorption. It is the best alternative to the traditional optical instrument for quick and more accurate contact angle measurement. VCA optima is a new generation Surface Analysis Systems by contact angle measurement.
