Large copolymer microspheres are useful as model systems for fluid mechanics experiments. Also as challenge particles for large pore filtration systems. They are also useful as experimental particles for acoustical and optical analytical systems. They are composed of polystyrene polymer, cross-linked with 4 to 8% divinylbenzene (DVB).
The particles are chemically inert; they can be washed with alcohol, vacuum or air dried, and autoclaved. For general purpose use such as fluid mechanics research, dispersion studies and centrifugation studies.
These particles are not intended for instrument calibration.
