SVTS Software modules

SVTS Software modules
The SVT software assures the intuitive use of the SVT 20N. DataPhysics has specialised in the development of highly precise, robust and reliable methods for evaluating drop contours in combination with statistical error analysis. At every step of hardware and software development the quality of the data produced by its combination has been a crucial consideration. The SVT software is designed as a modular program. Under Windows 7® / Vista® it works in 32- and in 64-bit mode; under Windows XP® only in 32-bit mode. The available software modules are:

SVTS 20 Basic software for control of the SVT 20 and the measurement of the interfacial tension. * video based measurement and presentation of the time and temperature dependent interfacial tension. * presentation of measurement values as well as the storage of video sequences for the calculation of fast processes. * control of the rotational speed and the inclination of the tilting base with the measuring cell and the camera position. * calculation of interfacial tension based on spinning drop contours according to various methods. Including the Young-Laplace method. * automatic calibration of the magnification of the drop. * automatic “drop hold” function. * automatic temperature recording. * automatic compensation of density and refractive index as well as of temperature dependent changes. * statistical evaluations and error analysis. * liquids database.	SVT 20 and 21 – Measurement of the interfacial dilatational modulus

SVTS 21 Extension modulus Oscillation/Relaxation. * calculation of surface and interfacial tensions, based on spinning drop contours, predefined speed increments and sinusoidal speed. variations for relaxation measurements. * recording and evaluation of video sequences, for analyzing fast relaxational oscillations and elongations of drops. * determination of dilatational interfacial elasticity of visco-elastic and visco-plastic materials.
	Interfacial dilatational modulus at different frequencies
SVTS 22 Extension modulus analysis of membrane covered and encapsulated spinning drops. * determination of deformation and elasticity parameters of membrane covered or encapsulated spinning drops with contours deviating from corresponding Young-Laplace shapes. * calculation of the effective deformation in relation to spherical or ellipsoidal rest resp. reference contours. * calculation of centrifugal stresses as a measure of the membrane or capsule loads. * calculation of membrane resp. capsule elasticity parameters from the effective deformation measure and the centrifugal stress. * volume calculation by numerical integration over arbitrary, even strongly deformed but still axis symmetric drop resp. capsule contours.
