SVT20

Advanced Spinning Drop Video Tensiometer

 

APPLICATION SCOPES:

Regular or Ultra-low Surface/Interfacial Tension Measurements and Interfacial Rheology Research.  A new concept of doing Spinning Drop Measurements; Video-based Tensiometer with rotational speed up to 20,000 RPM capable of reporting interfacial visco-elasticity.  Most widely used in oil, petroleum, emulsion, detergent, cosmetic, pharmaceutical and healthcare industries. But not limited to.

METHODS:

Spinning Drop Method.

FEATURES:

The SVT 20 is used for the software controlled and video supported measurement of:

  • Static and time dependent interfacial tension between two not completely miscible liquids.
  • Two and three-dimensional extensional relaxation of viscoelastic liquids and liquids droplets encapsulated or enclosed in membranes.
  • Yield point of e.g. liquid crystalline materials.
  • Thermal expansion coefficients of liquids.
  • All measurements are performed according to the Spinning Drop and Oscillating Drop Method.

The 64-bit Windows 7 & 8 compatible software developed for the SVT 20 offers:

  • Time dependent control of rotational speed as well as the adjustment of the capillary position in height and tilt.
  • Recording and evaluation of video sequences for the measurement of fast relaxational vibrations of drops.
  • Calculation of interfacial tensions from the shape of rotating drops (spinning drops) according to the Young-Laplace Equation as well as according to the Vonnegut approximation for sufficiently extended droplets.
  • Calculation of relaxational modules, yield points and other rheological parameters.
  • An extended liquid data base with more than 140 parameter entries.

PCA100

Robotic video-based Contact Angle Measuring Device

Measuring head for flat panel display, glass or very large samples in a non-man production process.

PCA100 Dosing

APPLICATION SCOPES –

The PCA 100 is designed for the automatic measurement of the wetting behavior of solids (e.g. wafers or glass substrates for flat panel displays) under clean-room conditions of any substrate size, as well as for series tests and systematic analysis. The PCA100 enables the reduction of subjective factors and time involved for contact angle measurements in quality control and production inspection. The instrument is available as a portable, hand-held, bench-top device or to be integrated in a process automation with a robot system.  For the software-controlled measurement and analysis of:

METHODS:

The Static and Dynamic contact angle according to the Sessile Drop Method as well as the analysis of;

  • The drop shape according to the Pendant Drop Method.
  • The wetting behavior on various solid surfaces.
  • The surface free energy of solids and their components.
  • The surface and interfacial tension out of the analysis of the drop shape.

FEATURES:

The PCA 100 consists of the basic instrument with the following technical equipment;

  • Measuring head with integrated optics, illumination and multiple dosing unit
    high-performance, telecentric lens with high light transmitting capacity and integrated aperture.
  • Video measuring system with high-resolution CCD-camera.
  • High-performance video digitizing board for the PC.
  • Illumination with continuously adjustable intensity for a homogeneous back lighting.
  • Control and measuring electronics for selection and positioning of the dosing needles.
  • Power supply with automatic voltage adjustment.
  • The 64-bit Windows 7 based compatible software SPCA. The analyses according to different methods were built into the software.
