7000 Series
Copolymer Particle Suspensions

Suspensions of large copolymer particles are useful as model systems for fluid mechanics experiments and as challenge particles for large pore filtration systems.

These products are designed to meet the need for particulate materials with a variety of particle sizes and properties. They are useful for applications such as filter evaluation, filter testing, fluid mechanics research, dispersion studies and many other research and development projects. They are not intended for use in instrument calibration or diagnostic reagents because they lack the exacting specifi cations needed for those applications.

Suspensions of large copolymer particles are useful as model systems for fluid mechanics experiments and 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 4-8% divinylbenzene (DVB). The particles are chemically inert. They can be washed with alcohol, vacuum or air dried. The polymer density is 1.05 g/cm3 and the index of refraction is 1.59 @ 589 nm. They are packaged as aqueous suspensions at 10% solids by weight.

Applications:
  • Research and development
  • Filter testing
  • Fluid mechanics testing
