OCA product series Optical contact angle measuring and contour analysis systems ranging from basic device to fully automated measuring systems for micro-structured samples

Optical contact angle measurement and drop contour analysis The optical analysis of drops that hang from a dosing needle or are placed on a solid surface facilitates the determination of different surface and interfacial parameters. The contact angle that a liquid drop establishes on a solid surface characterises the solid’s wetting behaviour with said liquid. Having measured the contact angles of multiple test liquids the surface energy of the solid can be determined and the latter can be used to calculate the work of adhesion for different liquids. Young-Laplace evaluation When no other factor...

OCA models The optical contact angle measuring and contour analysis systems of the OCA series combine high resolution optics, accurate liquid dosing and precise sample positioning into powerful and reliable measuring systems. schematic assembly of the OCA models surface tension measurement using the pendant drop method with an OCA 15EC The modular approach to all hardware components allows for a multitude of configurations, ranging from manually operated basic devices to fully automated high-performance measuring systems. All OCA models are based on a common design philosophy and are built with...

The OCA 25 is the all-purpose measuring device for contact angle measurements and drop shape analysis. The sample table of the OCA 25 is adjustable along all three directions in space via precision axes with hand wheels. Hence, a fast and exact manual positioning of the sample is always guaranteed, even when using high-performance temperature chambers like the electrical temperature control unit TEC 700U. contact angle measurement with an OCA 25 with a single direct dosing system SD-DM and an electronic syringe module ESr tems DDE/x. The latter are able to electronically position one to four...

The OCA 50 is the fully automatic measuring device for the time-saving analysis of the wettability of solid surfaces and the determination of the surface energy of solids. The sample table of the OCA 50 can be positioned along all three directions in space via electronic high-performance axes, with both extraordinary speed and highest precision. 12″ wafer surface energy ‘mapping’ using OCA 50L, an electronic direct dosing system DDE/4, four electronic syringe modules ESr and an electronic turn table with vacuum fixation ETTr/VAC. OCA 50 sample table with electronic high-performance axes for automatic...

The OCA 200 is the contact angle measuring and drop contour analysis system for microscopic and macroscopic structures. The software-controlled, electrically driven optic alignment enables the OCA 200 to adjust the observation angle and to focus automatically. With the trendsetting 10-fold zoom lens and the reliable auto focus system by DataPhysics, the OCA 200 is equipped to handle any kind of sample size from a macroscopic silicon wafer to the microscopic mesh structure of a coronary stent. contact angle measurements on micro-structured samples using an OCA 200 with FDDS FlexDrop dosing system....

Wide range of accessories With the manual and electronic direct dosing systems, electronic syringe modules ESr as well as the FDDS FlexDrop dosing system can be easily positioned above the sample table, allowing a choice of up to four liquids. system can instead be mounted onto the direct dosing systems, reproducibly dosing droplets as small as 2 nl and 25 pl, respectively. Further details are found in a separate data sheet. The electronic syringe modules ESr can be equipped with glass or disposable syringes and typically dose drops as small as 1 µl, allowing macroscopic samples to be conveniently...

Wide range of accessories Pursuant to the modular design of the OCA series, DataPhysics provides a wide range of accessories facilitating measurements under various environmental conditions. With different environmental chambers measuring temperatures from -30 °C to 700 °C can be reached. Dedicated to investigating the properties of metals, polymers or hotmelts in their liquid state is the electrical needle heating device NHD 700U. This special piece of development enables the dosing of molten solids at temperatures up to 700 °C. Hence the surface tension of, for example, molten aluminium can...
