The control panel TP 50 with touch screen and precision control wheel establishes a comfortable and intuitive control of all electrical components of a contact angle meter of the OCA series. This covers the electrically driven axes of the sample table, the electronic dosing systems and additional modules such as the humidity generator of the HGC series. The precision control wheel makes handling of the contact angle meter fast and accurate.

DataPhysics Instruments provides several sets of optical standards for performance validation. Each glass slide features a standard sessile, pendant drop, or lamella contour, for image capture and subsequent analysis.
The comparison of the measured value with the one stated on the slide is a crucial factor in the evaluation of instrument performance and reliability. All slides are manufactured with the highest precision, as per ISO 9001, in a controlled photolithographic process.
The OCAS basic set consists of two standardised sessile drop shapes and one pendant drop shape. Various other shapes are available.

The Topview Video System TVS opens up a new approach to contact angle measurements. It allows contact angles to be measured in indents or on assembled printed circuit boards. In addition to the contact angle, the TVS also enables the determination of surface homogeneity.
The Topview Video System TVS comprises an electronic syringe module which is used to dose a liquid drop via a bent needle. The drop is then observed from the top. If desired, the existing optics of the contact angle meter can be mounted on the TVS holding system.
For sample illumination, two different systems are available, which ensure an optimal contrast of the drop image.

All contact angle meters of the OCA series can be equipped with the top view observation video system TV-VS. The TV-VS is mounted above the main camera and provides an alternative view of the dispensed drops. Hence, a solid documentation of the sample mapping is guaranteed. The TV-VS features a USB-camera with a high-performance 6-fold zoom lens and an adjustable observation angle.

The Electro Wetting Platform EWP 100 is designed to investigate the influence of an electric field on the wetting and adsorption behaviour of modern, engineered materials. The EWP 100 facilitates the analysis of sessile and pendant drops in a defined electric field. The EWP 100 features electrodes integrated into the top and bottom plate and connectors. With different spacer elements, the distance between the electrodes can be adjusted.
