Optical & Force Tensiometry

We offer contact angle and surface and interfacial tension measurements using state-of-the-art optical and force tensiometry instrumentation. Our scientists are adept at both methods and provide measurements and analysis you need to solve a wide range of problems with wettability, adhesion, hydrophilicity and hydrophobicity, emulsification and demulsification, critical micelle concentration, and other application areas. Advanced measurements such as surface free energy and surface tension components (i.e. polar and dispersive) are also available. Utilizing these capabilities, we provide the data analysis and interpretation of your materials you need to improve or characterize surface cleanliness, surfactant performance, surface bonding, and more.

One-On-One Consultation

Project Analysis and Service Needs

We provide consultation with our customers to discuss appropriate measurements and expected outcomes to get the most out of the results for each application. Some key details we discuss during consultation include:

  • Best experimental approach including appropriate measurements using either or both force and optical tensiometry
  • Solid sample preparation, including any cleaning, modifications, and mounting
  • Experiment recipe, including appropriate volumes, concentrations, dispensing methods, sampling rates and durations
  • Design of experiments including number of measurements, samples, and replicates
  • Plans for data analysis and interpretation, and expected results

Precise Data When You Need It

Value Added Data Interpretation

Leveraging our one-on-one consultation and assessment we interpret the data and the results from the measurements requested. With advanced analysis using OneAttension software as well as expert knowledge on the theory and application of surface tensiometry results, we provide further insight into what the data really means and how it can be used to solve your specific problem.

Customized Deliverable Reporting

Reporting on the full picture

We deliver comprehensive reports which include the methods and techniques as well as the models used to generate your results. With our strict quality management system, we assure repeatable and reliable data generation and reporting. We will also provide you with additional test recommendations to help guide you in resolution. We work one-on-one with you to help you understand what the quantitative data means.

Industry and Applications

This technique is used in numerous industries to analyze and characterize a wide variety of samples, products, and material interactions:

  • Hard coatings, polymers, fibers, and textiles
  • Semiconductor, oils & lubricants, and agrochemicals
  • Medical devices, cosmetics, & healthcare

Optical and Force Tensiomerty Tests Provided

  • Surface Free Energy
  • Critical Micelle Concentration (CMC)
  • Surface Tension
  • Interfacial Tension
  • Contact Angle (static & dynamic)
  • High Pressure Contact Angle
  • High Pressure Interfacial Tension
  • Powder Wettability
  • Roughness-corrected Static Contact Angle
  • Liquid Density

Roughness-Corrected Contact Angle

The optical tensiometer we utilize is the only tensiometer available with integrated and fully automated surface roughness measurements and contact angle measurements. An automated XYZ stage first moves your substrate under the topography system and uses a fringe projection phase shifting technique to measure roughness. The stage moves back to the dispenser and automatically places a drop on the exact location of the roughness measurement. OneAttension software automatically calculates the roughness-corrected contact angle to give you better insight into your substrate’s wettability.

Surface Free Energy of Solid Surfaces

Surface free energy measurements go a step further than a simple contact angle measurement to provide you a quantitative measurement of a surface’s wettability. The analysis determines the polar and dispersive magnitudes of your substrates surface free energy, giving you insight into your surface’s affinity for polar (e.g. water) or dispersive (e.g. oils) liquids. This analysis can help optimize surface modification processes, such as plasma or chemical treatments used to increase surface energy for improved adhesion and wetting.

Surfactant Analysis

We can tailor our experimental approach to characterize your surfactants, whether it is time-dependent surface tension, equilibrium surface tension and surface tension isotherms, or critical micelle concentration (CMC) determination. Fully automated instrumentation eliminates experimental bias due to the user to provide the most accurate and repeatable data available

Transformer Oil Testing (ASTM D971 and IEC 62961)

Our fully automated force tensiometer with Du Nouy ring is especially designed to adhere to ASTM D971 or IEC 62961 standards for transformer oil testing. The automated system eliminates user bias and gives you the most accurate and repeatable results.
