The SCA software, designed for Microsoft Windows®, is the modular program for all OCA instruments. The modern user interface is highly customisable and offers every user an individual and ideally suited overview during measurements. A software-integrated extensive database comprises important physical and chemical parameters of a multitude of liquids and solids.
The SCA software features recording and storing of movie sequences which allows for a controlled evaluation of even the fastest processes. Due to a newly developed automation dialogue the automated control of all electronic components becomes effortless. For example, an entire sample can be mapped automatically determining the surface energy with up to four liquids. The position of every drop can either be set according to predefined patterns or individually using the intuitive visual drop positioning function.
The SCA software is divided into the following separately available modules:
Automation dialogue with visual drop positioning
The SCA 20 module is the base software module that enables the measurement of contact angles.
Contact angle measurement with SCA 20
With the SCA 21 software module the surface energy of solids can be determined by measuring multiple contact angles with different liquids.
Determination of the surface energy with SCA 21
The SCA 22 software module enables the measurement of surface and interfacial tensions according to the pendant drop method.
Surface tension measurement with SCA 22
The SCA 23 software module together with corresponding test pieces and vessels enables the measurement of the surface and interfacial tension based on liquid lamellas.
In conjunction with systems that can create oscillating pendant drops the SCA 26 software module can determine surface and interfacial rheological parameters.
Using the Topview Video System TVS the SCA 27 software module can determine contact angles on surfaces that are viewed in topview.
