RheometryRheometers are used to measure the rheology of fluids, which is the flow of fluids in response to an applied force. The most common types of rheometer include shear rheometers (capillary, cone and plate and rotational cylinder) and extensional rheometers. Viscometers are similar to rheometers however viscometers only measure the viscosity of a fluid.Mechanical TestingMechanical testing explores the elastic and inelastic nature of a material when force is applied. A mechanical test shows whether a material is suitable for its intended application by measuring hardness, tensile strength, elongation, elasticity, and fatigue limit.PolymersPolymers are large molecules made up of many repeat units. Natural polymers such as DNA and proteins are essential to life, whereas synthetic polymers such as polystyrene and polyethylene are used widely due to their functionality. Typical techniques for analysis include GPC, SEC, DSC, FT-IR and NMR.
