Since the early 90's AST has offered a complete line of contact angle systems ranging from the very basic to the completely automated. Through the VCA Optima series, the analytical technique of contact angle and surface energy has been transformed. This is achieved through the integration of a video imaging system, sophisticated software and precision mechanics. Our VCA systems provide quantitative, user independent, surface related information nearly instantaneously. As a function of the video capability, automatic, precise measurements are just a mouse click away. Real time images and data can easily be viewed, charted, stored for future reference or printed.  In addition to our popular VCA Optima series we also offer application specific systems such as the VCA-3000s for wafer surface analysis or the VCA-4600 series for flat panel surface analysis.  

The value of contact angle/surface energy measurements is apparent based on the array of industries and applications that utilize this analytical technique. Applications include determining: surface cleanliness, bondability, wettability, adhesion, biocompatibility and coating quality to name a few. The VCA Optima series can serve as a fast, quantitative quality control technique that establishes the foundation for any lab where surface characteristics are a factor for research or product development. Whether it's a simple contact angle measurement or timed dynamic capture studies, the VCA Optima series has a system to suit your needs.
