Large Surface Analyzer – LSA

Fully automatic measurements on many positions of large sample areas: Our Large Surface Analyzer – LSA combines a precise positioning robot with our Mobile Surface Analyzer – MSA for measuring surface free energy within a second. The system is especially suitable for quality control of cleaned, pre-treated or coated large surfaces due to its easy handling and programming as well as high measuring speed.

Measurement of surface free energy within a second

The automatically moved MSA, with its ability to take measurements in less than one second, is the fastest mobile instrument on the market for determining surface free energy with two test liquids. It does this by means of a non-contact pressure dosing system that places two drops on the sample, followed by an automatic image analysis of each drop including contact angle measurement and SFE calculation. With our Large Surface Analyzer – LSA, these features are enhanced using the quick and precise positioning of the instrument between measurements.

Powerful positioning robot in different sizes

The Large Surface Analyzer – LSA has one vertical and two horizontal axes and is designed to handle sample sizes of 565 × 495 mm. A second standard model allows operators to position the instrument as desired on an even larger surface of 2900 × 3150 mm. Upon request, customized systems in other sizes are possible.

ADVANCE – our intuitive software solution for your measurement tasks

The simple operation of the instrument goes hand-in-hand with the clear user guidance of our ADVANCE software. The relevant functions for each particular step are arranged in tiles which display all elements necessary in the context. By avoiding the use of menus and pop-ups, ADVANCE saves any unnecessary clicks and time-consuming searches for hidden elements. Particularly comfortable is the programming of automatic sequences that integrate the software-controlled components of the LSA in complete sample analyses with maximum flexibility. Using these automation programs provides high reproducibility and reduces the user’s influence on the results to a minimum.
