Sigma 700, 701 and 701F
KSV´s Sigma 700 and 701 tensiometers are run by a powerful WindowsTM software. The point-and click format of the software using drop-down menus, buttons, and icons is intuitive and user-friendly. The software included with the instrument allows the user to perform a variety of pre-programmed experiments which can be modified for particular needs. A wide range of data points and measurement parameters are stored in a database and can be easily retrieved and analyzed later, or alternatively exported to another data reduction software package.
Standard program includes:
- Surface and interfacial tension
- Dynamic advancing and receding contact angles (DCA)
- Powder wettability (contact angle of powders)
- Single fiber wettability
- Critical micelle concentration (CMC)
- Adsorption behavior of solids
- Surface free energy of solids (Fowkes, Wu, Acid-Base)
- Critical surface tension (Zisman)
- Wetted length of solids
- Density of liquids
All sections and programs can be accessed from the Main Menu. Once an experiment has been chosen, the various information and parameters are entered in the Experimental Setup. All parameters that are necessary to obtain the desired data from the measurement must be entered at this stage. The Setup page helps to keep the data organized and makes it easier to search for a specific measurement afterwards.
The actual performance of experiments (Surface/Interfacial Tension, Contact Angle, Critical Micelle Concentration, Absorption, for example) occurs after the Experimental Setup has been filled out and the materials for the experiment are in place. Once the final experimental controls have been chosen the experiment is started. The experiment will then continue unsupervised until completion.
Afterwards you can return to the data for further analysis in the Data Reduction and Analysis section. There is an option of viewing and editing the Experimental setup which can be very helpful if the data produced should be recalculated based on new information about the materials involved. A variety of graphs for your data can be displayed and printed and calculation of additional results and export of data can be done.
Sigma 702, 702ET and 703D
Sigma 702 and 703D are built as stand-alone tensiometers with build-in displays for viewing experimental results. However the experimental data can be stored to an external PC for further analysis via USB-cable and a special software program. The software stores the data in either ASCII or spreadsheet format.
