Single Fibre Tensiometer K100SF  


รหัส : K100SF
รุ่น : Single Fibre Tensiometer K100SF
รายละเอียดย่อ :

Extremely Accurate

Precision in a new dimension: the PC-controlled measuring system K100SF determines the surface and interfacial tension of liquids and solids with the highest effectiveness and efficiency.
รายละเอียดทั้งหมด :

The built-in ionizer ensures optimal measuring conditions. The high accuracy of the measuring instrument guarantees the exact characterization of the finest single filaments.

No Chance for Electrostatics - Measurements with the Ionizer
When conventional tensiometers are used to make sensitive measurements on small samples, single fibres or insulating plastics electrostatic forces of attraction occur between the solid and the liquid surface - the measured force or the detected surface height is incorrect.

KRÜSS has thought out a solution to this problem (and also applied for a patent for it): the use of an ionizer. This ionizes the air in the sample chamber for a short time and in this manner eliminates any electrostatic charges. The measurement can now be made without any interference with the highest degree of accuracy.
 
 
Features
  • Fully automatic measurement of contact angle and sorption, even on single filaments 
  • Surface energy determination on powders, small plates and single fibres
  • Extended CMC - Critical Micelle Concentration - determination with new innovative double dosing system 
  • Surface and interfacial tension measurements of liquids 
  • Determining the density of liquids
  • Built-in ionizer for eliminating electrostatic charges
  • Controlled by LabDesk™ software
  • Doors made of high-grade glass and covering of sample chamber made of brushed stainless steel for maximum chemical and thermical resistance.
 
Application
  • Characterization of natural and synthetic fibres
  • Development of carbon and glass fibres
  • Optimization of hair care products
  • Prediction of interactions between fibre and matrix
