LUM GmbH – LUMiFrac
The LUMiFrac is an innovative adhesion analyser, which employs centrifugal forces to determine temperature-controlled tensile as well as shear strength.
It employs centrifugal forces to stress multiple samples at once. It provides adhesive and tensile strength as well as shear strength as an absolute physical quantity in N/mm² (MPa).
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 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.
