This group of products is 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 and 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.
Particles of this series are of special interest for research in light scattering, microporous filter checking and aerosol particle generation. The polystyrene microspheres have a density of 1.05 g/ cm3 and a refractive index of 1.59 @ 589 nm. Particle diameters are measured by optical microscopy, photon correlation spectroscopy or light scattering. They are packaged as aqueous suspensions at 10% solids by weight.
The 5000 Series particles range up to 3.1 microns in size. If you require larger particles, please refer to our Copolymer Microsphere Suspensions - 7000 Series particles.
