Size Standards and Count Control Particles

Certified Particle Size Standards traceable to the Standard Meter through the National Institute of Standards and Technology (NIST).

Demonstrate the traceability of their analytical methods as required by ISO 9000, ISO 10012, ANSI/NCSL Z540, GMP/GLP and other standards and regulations

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 instrument.
Thermo Scientific* Duke Standards* 4000 Series Monosized Particles are excellent for use with any application that requires a NIST* traceable size standard with a very narrow standard deviation.
Thermo Scientific* Copolymer Microsphere Suspensions 7000 Series are designed to meet the need for particulate materials with a variety of particle sizes and properties.
Thermo Scientific* Duke Standards 9000 Series Glass Particles are dry glass NIST traceable size standards.
The Thermo Scientific* Dri-Cal Particle Size Standards are particle size standards for instruments that require dry particles.
The Thermo Scientific* Ezy-Cal Count Precision Size Standards are easy-to-use liquid particle count controls at 2000 particles per mL.
Thermo Scientific* Pharm-Trol Count Precision Size Standards are for USP and verification.
Thermo Scientific* 3000 Series Nanosphere Size Standards are excellent for use with any application that requires a NIST traceable size standard with a very narrow standard deviation.
Thermo Scientific* 5000 Series Polymer Particle Suspensions are of special interest for research in light scattering, microporous filter checking, and aerosol particle generation.
The Thermo Scientific* 8000 Series Silica Particle Size Standards are monodisperse silica microspheres, NIST traceable size standards.
Thermo Scientific* Duke Standards 3K/4K Series Particle Counter Standards are particle size standards for use in particle counting validation for particle counting instruments.
