Description

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

Specifications

• Additive: Contains trace amount of surfactants
• Material: Polystyrene Divinylbenzene
• Quantity: 15mL
• Stability: 24 months

• Includes: Material Safety Data Sheet (MSDS), Certificate of Calibration and Traceability to NIST
• Particle Density: 1.05g/cm³
• Refractive Index: 1.59 at 589nm (25°C)
• Storage Requirements: Store at room temperature or keep refrigerated. Keep bottle tightly sealed to avoid contamination.
