The LUMiFrac accomplishes this by directly applying an incrementally increasing centrifugal force to the specimen being tested. It determines with high resolution the RPM at the moment of fracturing (employing CAT-Technology = Centrifugal Adhesion Testing Technology).
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%. Starting as an idea for an easier and time-saving determination of adhesive properties, the multipatented new adhesion testing technology now revolutionizes the analysis of your composite materials and bonded parts. You can even work with multi-layered films; having an immense variety of applications.
The LUMiFrac is a research and QC tool for the adhesive formulation and surface treatment industry; lacquer coatings, joint wood products, composite materials in automotive and aircraft industries, adhesive tapes, multilayer foils for packaging or thin metal films on plastics and optical substrates, e.g., eyeglasses, mirrors, and many more.
Different test stamps are available to cover more than enough material combinations and to enable a wide range of applied loads. In order to facilitate sample preparation specially designed tools are available. Combine everything you have just read, put it into action, and it makes for not exceptionally accurate and reproducible data, but also for an exceptionally happy user.
The LUMiFrac comes certified, factory precalibrated and is ready-to-go.
