2000 Series Uniform Polymer Particles

1.00

These microspheres show a size distribution which is appropriate for methods that need particle size uniformity between monodisperse (highly uniform, <5% CV**) and polydisperse (widely distributed, <12% CV). These include instruments for light blockage, light diffraction, acoustical imaging, electrolyte displacement or other methods used for analysing wide size range materials. The material is composed of polystyrene cross-linked with divinylbenzene. This gives the particle good durability and chemical stability. They can be washed in water-alcohol mixtures and resuspended in water, air or similar media. The density of polystyrene is 1.05 g/cm3, and the index of refraction is 1.59 at 589nm (25C). Microspheres in this series are packaged as an aqueous suspension in 15 mL dropper-tipped vials.

Description

(NIST) traceable particle size standards enable laboratories to validate or calibrate their particle sizing instruments or methods in order to comply with ISO, GMP, GLP and other international standards. They are traceable to certified reference materials from international standard organisations through an unbroken chain of measurement leading back to the standard meter.

These products show a well defined size uniformity and are NIST traceable Brands: Thermo Scientific, Applied Microspheres Laser diffraction instruments measure across a wide range of sizing. In most applications the product measured has a fairly wide distribution. Thermo Scientifics’ 2000 series “Uniform Polymer Size Standards” are NIST traceable size standards with a somewhat wider distribution than our normal standards. They are well suited for laser diffraction applications. This product line ranges in sizes from 5 to 40 microns in diameter. Brand: Thermo Scientific
