Mobile Surface Analyzer
Analyzing wettability in a second with only one click
A powerful instrument for quality control of pretreated, coated, or cleaned surfaces: The MSA One-Click SFE Mobile Surface Analyzer measures wettability by means of the surface free energy automatically and extremely fast.
With just one click, the MSA doses parallel drops of two liquids, 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 result allows well-founded statements about the general wettability by aqueous or organic liquids as well as the adhesion.
Thanks to the reliable and pre-defined measuring procedure, user-independent results are guaranteed and errors due to incorrect operation are virtually ruled out.

Experience how much time and effort the MSA One-Click SFE spares when doing quality control for cleaned, coated, or pretreated surfaces.
The MSA One-Click SFE is optimally equipped for the mobile and non-destructive quality control due to the power connection to a notebook and its low weight and small footprint. The instrument analyzes samples of any size, such as automobile bodies. It provides reliable values even when measuring vertically or overhead and also works on slightly convex samples.
The intuitive ADVANCE software for the instrument uses proven scientific methods to calculate the surface free energy. Notably the determined polarity of the surface gives direct feedback to the effect of pretreatment methods such as plasma treatment.
Many features for easy and reliable wetting analysis: the MSA One-Click SFE makes test inks and dyne pens matters of the past.
The integrated Liquid Needle dosing unit dispenses two parallel drops within milliseconds with high volume precision. This simultaneous dosing of two drops eliminates the need to change the test liquid during the measurement, as is the case with conventional dosing techniques. The kinetic energy is kept low in order to prevent unwanted prewetting of areas around the drop, which could falsify the result.
Cartridges that can easily be refilled outside the instrument make for simple operation of the dosing system. Fully charged, the instrument is capable of dosing 1000 droplets of each liquid.
A dosing unit for two liquids. A camera with a lens. A light source and an aperture. Lots of electronics. In a nutshell, that’s what it takes to automatically determine the SFE. Having all these parts tightly packed in a durable, hand-held instrument makes the MSA a small miracle.
The compactness of the MSA is only surpassed by its versatility. You can use it on samples as thin as a chopstick or as large as a car body. It works on curved surfaces, vertical walls, or overhead. Believe it or not, promising tests are even being made at zero gravity.
Once you have verified that your surface meets all of your quality standards, you certainly don’t want it to be spoiled by the measurement. With that in mind, the MSA’s small, soft footprint leaves no traces on the sample except two micro-drops of pure liquid.
Constructed with chemically-resistant parts and enclosed by a high-grade metal housing, the instrument is robust and ready for the factory floor.
Estimating the surface free energy (SFE) using manual brushstrokes of a series of liquid mixtures frequently gives misleading results. In contrast, the MSA determines the SFE scientifically using the contact angle as a direct measure of wettability. Since it does its analysis even faster than test inks, there is no reason to hold on to this ancient method.
