Scratch Tester

Scratch Tester

Patented scratch technology

Scratch testers from Anton Paar are used to characterize film-substrate systems and to quantify parameters such as adhesive strength and friction force by using a variety of complementary methods. This makes scratch testers invaluable tools for the determination of coating adhesion, scratch resistance, and mar resistance in research, development, and quality control.

5 Reasons

Access to unique and patented synchronized panorama

Anton Paar is the unique holder of the patents US 8261600 and EP 2065695. After the scratch, you have the possibility to record the full panorama without loss of image resolution. The panoramic image is displayed in a perfectly synchronized way with scratch data. Once your panorama is recorded, you can re-analyze your results at any time.

More insights into true penetration depth for elastic recovery studies

The displacement sensor monitors the surface profile of your sample before, during, and after a scratch (Patent: US 6520004). This means you can evaluate the penetration depth of the indenter during and after the scratch for even more reliable insights into scratch and mar resistance.

Accurate force control even on complex surfaces

The system’s active force feedback ensures reproducible scratch testing, even when you investigate more complex surface geometries like non-parallel, rough, or curved samples. Anton Paar’s testers are the only commercially available systems that have active force feedback.

A platform to suit your needs and budget

The modular platform portfolio provides the ideal instrument for each budget and force range (dedicated instrument for the micro, nano, and ultra nano range). A highlight is the high-quality but affordable mechanical surface testing platform for the micro range which is specially designed for high-throughput and fast measurements.

Save time changing between high-quality objectives

The scratch testers’ integrated microscope consists of a turret with high-quality Olympus objectives and a USB video camera rather than a single-objective microscope of lesser quality. It is easy to change magnifications for imaging, which saves you time and ensures smooth testing of a number of different samples in one series.
