Contact angle technology for wetting measurements in QC

| By Mary Page Bailey and Gerald Ondrey

With Ayríís (photo), this company has optimized the contact-angle method for quality assurance and developed the first solution for measuring the 3D contact angle. The instrument creates a virtual 3D model of the water drop dosed during the measurement and determines the contact angle reliably and automatically on the basis of this spatial image. The measurement takes only seconds and requires no prior knowledge or training. To prepare the quality-control (QC) checks, sample types can be created via the touch display and tolerance limits for the contact angle can be set. — Krüss GmbH, Hamburg, Germany
