How does discovering the mechanical properties of a product help determine the process for manufacturing? An ADMET Customer presented us with a problem. Their plastic disposable pipette tips lacked sufficient stiffness to ensure the customer’s success in dispensing fluids.

Was is the formulation of resins, was it a deformation in the mold, or some other factor? The objective was to find a testing machine with servo control and constant rate of crosshead movement to apply a bending force to the end of the pipette tip. By acquiring the flexural strength of the tip… Read more
