Duke Standards 2000 Series Uniform Polymer Particles

Thermo Scientific* Duke Standards 2000 Series Uniform Polymer Particles are uniform, NIST traceable polystyrene DVB particles with wider size distributions which mimic real world particles and work better on laser diffraction type instruments.
These polymer particles meet the need for NIST traceable size standards that have slightly wider distributions than our monodisperse 3000/4000 series size standards. They are suitable for laser diffraction and other methods for analyzing wide size range materials. The wider distribution of these particles 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 1.05g/cm3 and the index of refraction is 1.59 at 589nm (25°C). The particles are packaged as an aqueous suspension in 15mL dropper-tipped vials.

Recommended for: Excellent for use with any application that requires a NIST traceable size standard with a very narrow standard deviation[clear]
