The polystyrene microspheres have a density of 1.05g/cm3 and a refractive index of 1.59 at 589nm. 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 7000 Series Copolymer Microsphere Suspensions.
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. 5003B and 5003C). Please allow 10 working days when ordering these fill volumes.
Material Safety Data Sheet (MSDS) and general product handling insert sheet
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.
