Multipurpose apparatus for screening a combination library with high throughput. SOLlITION: The apparatus comprising sample holder for holding the components of 8 library, probe array for perturbing an independent library component mechanically, and a sensor array for measuring response to mechanical perturbation of each library component. During scraening operation, the apparatus replaces the sample array (sample holder) and the probe array and perturbs an Independent library-component
mechanically. A material sample tested based on a large number of different bulk physical properties including Young's modulus (bending, uniaxial drawing, biaxial drawing, tearing), hardened indentation), fracture (toughness) adhesion, flow
viscosity, melt flow Index, rheology).
