LUMiFrac - The New Standard in Adhesion & Cohesion Testing

The Adhesion Analyser LUMiFrac® is the new benchmark for determining adhesive and tensile strengths, the LUMiFrac employs centrifugal forces to stress multiple samples at once. It provides adhesive and tensile strength as an absolute physical quantity in N/mm².

The analyser accomplishes this by directly applying an incrementally increasing radial centrifugal force to the specimen being tested. It determines with high resolution the RPM at the moment of fracturing. All data is transmitted to the well-known and popular operating software SEPView, which automatically calculates and displays the critical force/strength of failure in real time. 

Furthermore, it allows to analyze, compare & calculate statistics and combine results for up to tens of samples. Related data, as figures of fracture pattern, may be taken into account as well. Test sample positioning is as simple as 1-2-3. No clamping or special precautions are needed. Just slide up to 8 samples into marked rotor locations and you are ready to go.

The unique multisample approach of testing 8 samples simultaneously results in an unparalleled accuracy and reduces measuring time by 85%.
