    Theta Flow

    Premium contact angle meter suitable for demanding surface research and quality control.

    The Attension® Theta Flow from Biolin Scientific measures contact angle, dynamic contact angle, surface tension, surface free energy and more. Designed around practical, everyday use, it introduces a set of features that automate or sense key instrument settings, delivering better data quality and repeatability with minimal effort from the user. An integrated touch display allows the instrument to be operated directly at the bench.

    WHY CHOOSE THIS PRODUCT

    Three reasons to invest

    • Automation at an all time high. Camera autofocus keeps the image sharp at all times, automatic surface mapping moves the sample between measurement positions, and the industry leading OneAttension software generates results automatically. Together these simplify the measurement and raise accuracy.
    • Accuracy and user independence. A 5 MP camera, image enhancement through DropletPlus technology, and built in sensors that monitor the surrounding environment for full traceability. Reliable data is the foundation of measurements that do not depend on who runs them.
    • Easy to use with an integrated touch display. Everything from filling the liquids to changing the sample is handled directly at the instrument in seconds, making measurement preparation far smoother.
