Polymer spheres and microspheres are often used as tracers and seeding particles for flow visualization applications and particle image velocimetry (PIV). Highly characterized particles with precision size ranges and controlled true particle density enable applications in many simulations and models in biotechnology, medical devices, instrumentation, calibration, marine and environmental sciences, aerospace, fluid mechanics and other fields allowing for valuable insights into various fluid-particle interactions and related phenomena.
