7000 Series Copolymer Microsphere Suspension 3.2 - 222µm
Copolymer Microsphere Suspensions 7000 Series are designed to meet the need for particulate materials with a variety of particle sizes and properties.
Suspensions of large copolymer microspheres are useful as model systems for fluid mechanics experiments and as challenge particles for large pore filtration systems. 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 specifications needed for those applications. They are also useful as experimental particles for acoustical and optical analytical systems.
Suspensions of large copolymer microspheres 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. The polymer density is 1.05 g/cm3 and the index of refraction is 1.59 at 589nm. They are packaged as aqueous suspensions at 10% solids by weight.
Storage Conditions: Store at room temperature or keep refrigerated. Keep bottle tightly sealed to avoid contamination.
Includes: Material Safety Data Sheet (MSDS) and general product handling insert sheet.
