Uniform NIST traceable polystyrene DVB microspheres with wider size distributions which mimics real world particles and works better on laser diffraction instruments.
Product Detail
These polymer spheres meet the need for NIST traceable size standards that have slightly wider distributions than our monodisperse 3000/4000 series size standards. These products are suitable for laser diffraction and other methods for analyzing wide size range materials. The wider distribution provides light scatter across a range of detectors resulting in a more repeatable measurement.
The material is composed of polystyrene cross-linked with divinylbenzene. This gives the particle good durability and chemical stability. The density of the polymer is 1.05 g/cm3 and the index of refraction is 1.59 at 589 nm (25°C). The microspheres are packaged as an aqueous suspension in 15 mL dropper-tipped vials.
