Many industrial sectors are driving innovations in new materials from biomaterials, bone, fibers, threads, thin films, wire and more. However, that innovation requires measuring the mechanical properties of miniature samples. Few materials testing systems are able to measure very low forces and small displacements on samples that can often be difficult to hold. Furthermore, many researchers also have a need to record microscopic material behavior while the sample is under load. The line of eXpert 4000 series MicroTest Systems are ideally suited to meet these demanding testing requirements.
