MSA – Mobile Instrument for Surface Wettability Analysis
The MSA (Mobile Surface Analyzer) is a portable instrument designed for fast, automatic, and non-destructive wettability analysis. It measures the contact angle and calculates the surface free energy (SFE) of solid surfaces in seconds, making it ideal for quality control and process optimization directly at the production line.
The MSA One-Click SFE version uses standard test liquids to determine the SFE with a single click, ensuring highly repeatable results without user influence. The MSA Flexible Liquid version offers the added ability to work with custom liquids, making it suitable for applications where unique formulations, such as inks or coatings, need to be evaluated under real conditions.
MSA Flexible Liquid
Mobile Surface Analyzer for Custom Liquid Applications
The MSA Flexible Liquid configuration enables automated, non-destructive contact angle measurements using freely selectable liquids, such as inks, coatings, or adhesives. This makes it ideal for evaluating real-world wetting behavior directly on solid materials and finished products during manufacturing or quality control. The instrument delivers quick, repeatable results and supports advanced surface analysis methods using a mobile, production-ready design.
Applications
☑️ Analyzing the wetting behavior of formulations such as paints, coatings, or adhesives
☑️ Checking wettability of plastics, glass, ceramics, wood, paper, or metal
☑️ Quality assurance of activation processes such as plasma, flame, or corona treatment
☑️ Testing the effectiveness of hydrophobic coatings and other surface treatments
☑️ Measurements on large workpieces and finished products (e.g. car bodies, aircraft parts, walls)
Measuring Methods
☑️ Contact angle of a drop on a solid surface
☑️ Surface free energy (SFE) of a solid using contact angle data
☑️ Surface tension from drop curvature on a circular pedestal
☑️ Perform up to 20 consecutive measurements with grouped results
Measuring Results
☑️ Static contact angle
☑️ Surface free energy (SFE) using models:
• Owens-Wendt-Rabel-Kaelble (OWRK)
• Fowkes
• Wu
• Zisman
• Equation of Stat
MSA One-Click SFE
Mobile Surface Analyzer for Fast, Automated Surface Free Energy Measurement
The MSA One-Click SFE configuration is designed for fast and automated wettability analysis, making it ideal for quality control of pretreated, cleaned, or coated surfaces. With just one click, the instrument doses two test liquids simultaneously, performs contact angle measurements, and calculates the surface free energy (SFE) — all within a second. This standardized process ensures user-independent results with minimal risk of error.
Applications
☑️ Determining wettability before coating or bonding
☑️ Quality assurance of plasma, flame, or corona treatment
☑️ Verifying surface cleanliness
☑️ Testing hydrophobic or other coatings
☑️ Measurements on large or finished parts (e.g. car bodies, aircraft parts, walls)
Measuring Methods
☑️ Simultaneous contact angle measurement of two drops
☑️ Surface free energy (SFE) using contact angle data
☑️ Surface tension using drop curvature on a circular pedestal
☑️ Batch measurements of up to 20 cycles with grouped results
☑️ Remote control integration via ADVANCE for automated systems
Measuring Results
☑️ Contact angles of two liquids
☑️ Surface free energy (SFE) using models:
• Owens-Wendt-Rabel-Kaelble (OWRK)
• Fowkes
• Wu
• Zisman
• Equation of State
☑️ Work of adhesion
☑️ Interfacial tension
☑️ Spreading coefficient
