Measuring Wettability: Contact Angle Measurement Systems
Contact angle measurement systems like goniometers or optical tensiometers, are instruments used to determine the wettability of surfaces by measuring the angle formed where a liquid droplet contacts a solid surface. These systems are crucial for characterizing surface properties and understanding adhesion, coating, and cleaning processes.
: Many contact angle measurement instruments help us measure the droplets that contact the solid surface.
Orbit Research Associates Private Limited provides advanced high-tech instruments that help you.
Some of them are listed below:-
Getting rid of any user intervention and result interpretation whatsoever, our Ayríís uses groundbreaking technology for perfectly reliable QC checks of wettability. With just one click and in seconds, the 3D Contact Angle of water is measured and auto-validated with a simple passed/failed message using preset quality limits. The highly advanced 3D drop projection technique of Ayríís provides for automatic self-checking of consistency and plausibility of each result. As a mobile, stand-alone instrument with easy-to-exchange rechargeable batteries and prefilled cartridges, Ayríís is prepared to operate 24/7 on your production site.
MSA measures surface-free energy with two liquids, fully automatic and mobile using our new “One-Click SFE” method. The MSA doses two parallel drops with one click, followed by the direct analysis of the contact angles and the derived results of the surface free energy. All steps are automated and happen within a second.
The precise measurement and scientific evaluation are performed with a single button click. Thus, measurement errors due to incorrect operation are virtually ruled out.
The Micro configuration of our DSA30 was specially designed to investigate the contact angle on surfaces that require very small drops for analyzing them. The DSA30M solves this task with a picoliter dosing system and powerful microscope optics. The result is a versatile instrument that provides precise contact angles and surface-free energy results for samples such as hairs or the screw windings of dental implants.
The available dosing units for 20 or 60 picoliters minimum volume dispense microscopically small drops of test liquid onto the sample. The fine positioning of the dosing unit and the sample allows precise placement of the drops. Working with two test liquids also enables the surface free energy to be calculated. This result provides important information for the adhesion, e.g. of fiber coatings.
Drop Shape Analyzer DSA30R performs measurements of Interfacial Rheology and gives relevant results for optimizing products and processes.
The measuring principle of the DSA30R involves evaluating video images of drops or gas bubbles at a dosing needle to measure the surface or interfacial tension (SFI/IFT). The interface size is sinusoidally changed during this process. The SFT/IFT is measured as a function of the surface change and is also sinusoidal in the case of samples containing surfactants.
The dosing unit’s extremely precise piezo drive enables exact sine waves in a frequency spectrum of 0.001 to 20 Hz, so the measurements cover a very wide dynamic range.
The entry-level instrument is easy to use and reliable for measuring contact angle, Surface Free energy, and Surface Interfacial Tension measurement by the Pendant drop method.
The trend to water-based bonding, coating, and printing on plastics has made solving wetting problems an important challenge, With the DSA25, KRUSS covers the increasing demand for rapid wetting tests.
DSA30 is a robust instrument that can be used flexibly for the precise measurement of contact angle and surface free energy. With high-quality components and various automation options, the DSA30 analyses wetting and adhesion on solid surfaces. Fast measurements and simple operation make the instrument a valuable part of your routine quality control.
Drop Shape Analyzer (DSA100) is a high-quality system solution for almost all tasks in the analysis of wetting and adhesion on solid surfaces. From the basic unit for precise measurement of the contact angle to the fully automatic expert instrument for serial measurement of surface free energy, This is the right instrument for your special requirements.
The Drop Shape Analyzer – DSA100HP is our high-quality solution for the precision measurement of contact angle as well as surface and interfacial tension under pressures up to 1750 bar. To carry out the measurement, the DSA100HP’s high-resolution camera records video images of dosed drops through the pressure cell’s viewing windows and these are then evaluated in real time.
It is the only instrument in the world to use the top-view reflection method for measuring the contact angle of a liquid on a solid from above. TVA100 determines the contact angle using the radius of curvature of the upper surface of the drop. The innovative measuring method is particularly suitable for measurements in depressions and on concave surfaces where drops cannot be analyzed using the conventional side view.
The measuring head is available as a module for the well-proven KRÜSS DSA100, DSA30, and Easy Drop instruments and also as an independent portal system for contact-free measurements on large samples.
