The innovative MSA can be operated with one button to titrate two liquids at the same time, and the surface free energy and its composition can be determined by the contact angle of the two droplets on the surface of the substrate. All operations only need one click, and all operations are completed automatically. This kind of measurement efficiency is unprecedented. It provides the most ideal technical support for solid surface treatment optimization, wettability evaluation and coating quality inspection.

Innovative two kinds of test liquid simultaneous dripping module

The double-drop system can titrate two liquids simultaneously in an instant, achieving high volume accuracy and minimum kinetic energy. Titration of two droplets at the same time avoids the problem of replacing the test liquid in the common dropping system during the test, and the non-contact dropping method avoids contamination or damage caused by unnecessary sample contact.

The liquid storage tube can be taken out of the instrument and is easy to fill with liquid. After all the test liquids are filled, each liquid of the handheld MSA can be titrated 1000 times without filling the liquid.

We have also developed an optional titration system that uses traditional disposable syringes for difficult-to-clean liquids such as adhesives, inks or paints.

Simple operation and diverse applications

MSA is suitable for use with a laptop computer. It is powered by USB. It is light in weight and small in size. MSA is an ideal tool for mobile and non-destructive quality control. It can analyze samples of any size, such as the surface of automobiles, and can accurately measure vertical, elevated and curved samples.

The intuitive software ADVANCE automatically calculates the surface free energy according to the scientific model, and can obtain the polar composition information of the surface to provide credible guidance for applications such as plasma activation.

One-button operation can also eliminate the influence of human operation on experimental results, so as to achieve accurate measurement and scientific evaluation.
