Thermo Scientific™ Duke Standards™ 2000 Series Uniform Polymer Particles

Description

Analyze wide size range materials through laser diffraction or other methods with uniform polymer particles that mimic real world particles.

Analyze wide size range materials through laser diffraction or other methods with Thermo Scientific™ Duke Standards™ 2000 Series Uniform Polymer Particles, NIST™ traceable polystyrene DVB particles with wider size distributions that mimic real world particles and work better on laser diffraction-type instruments. Particles meet the need for NIST traceable size standards that have slightly wider distributions than our monodisperse 3000/4000 series size standards. The wider distribution provides light scatter across a range of detectors, resulting in a more repeatable measurement.

Features:

• Material is composed of polystyrene cross-linked with divinylbenzene, giving the particle good durability and chemical stability
• Density of the polymer is 1.05g/cm³ and the index of refraction is 1.59 at 589nm (25°C)
• Particles are packaged as an aqueous suspension in 15mL dropper-tipped vials
• Excellent for use with any application that requires a NIST traceable size standard with a very narrow standard deviation
