Surface Analyzer Range (LSA)

The LAUDA Scientific Surface Analyzer (LSA) series is designed for the determination of wettability, work of adhesion, printing and absorption, as well as surface and interfacial tension. With its modular design, the LSA range is versatile, catering to both quality assurance and research and development applications.

Innovative features:

• Unique drop shape adjustments
• Telecentric lenses
• High-speed video recording
• Flexible software
• Extremely precise results

The accuracy of the contact angle and surface tension measurement depends on both the optical system and, to a large extent, the software algorithms processing the captured imagery.

Additionally, the system offers flexibility through multiple data export methods, a focus assistant, evaluation modules for surface energy, control options for sample axes and rotating tables, and various dosing systems tailored to your specific application.

Moreover, the accuracy of contact angle and surface tension measurements based on optical systems largely depends on the software algorithms. In this regard, LAUDA Scientific offers a versatile package for every application, adaptable to different tasks and accessories. Features like high-speed video recording, predefinable methods, an extensive fluid library, and comprehensive adaptability make it highly effective in practice.

Furthermore, there are specialized methods for very small contact angles and automatic baseline determination, even for difficult surfaces. In addition, various data export formats, a focus assistant, evaluation modules for surface energy, control options for sample axes and rotating tables, and a variety of dosing systems are available to support you and your application.

Applications for contact angle measurement

• Wettability and liquid-solid interactions
  You can determine the surface free energy, along with its polar and disperse properties of your surfaces via contact angle measurements which can be used for prediction of surface-liquid interactions.
• Cleaning and coating
  Advancing and receding contact angles, along with their hysteresis, characterize the complete wetting and dewetting process for cleaning and coating processes.
• Self-cleaning and spraying
  To optimize spraying and wetting processes you can simulate the wetting and de-wetting processes with unique accessories to test it with different forces.
• Work of adhesion
  For coatings, printing, etc., the strength of wetting and adhesion to the surface is decisive for processing and a successful application.
• Printing and absorption
  With high-speed cameras, you can determine how quickly printer inks are absorbed by micro-porous photo papers and optimize contour sharpness and inter-color bleeding.
