Suspensions of large copolymer microspheres are composed of polystyrene polymer, cross-linked with 4 to 8% divinylbenzene (DVB). The particles are chemically inert and can be washed with alcohol and vacuum or air dried. The polymer density is 1.05g/cm3 and the index of refraction is 1.59 at 589nm. They are packaged as aqueous suspensions at 10% solids by weight.
15mL, 100mL and 1000mL bottle sizes available. 15mL (“A” Part No. bottles), 100mL (“B” bottles) and 1000mL (“C” bottles) are packaged to order; example (Part No. 7503B and 7503C). Please allow 10 working days when ordering these fill volumes.

High concentration polymer particles > 3μm used in filter evaluation and testing, fluid mechanics research, dispersion studies and many other research and development projects. Not intended for use in instrument calibration or diagnostic reagents because they lack the exacting specifications needed for those applications. Also useful as experimental particles for acoustical and optical analytical systems.Not intended for use in instrument calibration or diagnostic reagents.
