Kruss Mobile Surface Analyser MSA

Scientex and Kruss have announced the Mobile Surface Analyser MSA. The instrument measures wettability based on the contact angle with two test liquids simultaneously and fully automated using the ‘One-Click SFE’ method. Values for the two contact angles, the surface free energy of the sample and its polar part are available within 1 s.

The product doses two parallel drops within milliseconds, with high-volume precision and minimal kinetic energy. In spite of its high speed, the procedure resembles the gentle way of placing a drop with a dosing needle. The contactless method, without the usual dosing needles, prevents undesirable contact with the sample and possible damage or contamination of the probe.

The portability of the product makes it convenient to connect to a notebook with only a USB power connection. With its low weight and small footprint, the device is designed for mobile and non-destructive measurements on any sample size, even for vertical surfaces or convex surfaces. It is a mobile quality control instrument for pre-treated or coated surfaces.

The modern, intuitive software automatically calculates the surface free energy based on meaningful scientific models. Due to the simple measuring sequence and easy-to-use software, data is acquired seamlessly.

Applications include measurement on large work pieces and finished products such as automobile parts; determination of the wettability of solid materials before coating or bonding; quality assurance of pre-treatment, coating processes and cleaning steps; testing the effectiveness of hydrophobic coatings.
