Size Standard Particles

9000 Series Glass Particle Standards Thermo Scientific™

Replace polystyrene spheres in many applications with Thermo Scientific™ 9000 Series Glass Particle Standards, dry glass NIST™-traceable size standards. Glass microspheres can be used in any application that requires a NIST™-traceable size standard with a narrow size distribution where sample conditions may not be suitable for polystyrene spheres. The glass microspheres provide a better tolerance to chemicals and solvents in addition to higher mechanical and thermal stability.

SURF-CAL™ Particle Size Standards Thermo Scientific™

Simplify the preparation of calibration wafers with Thermo Scientific™ SURF-CAL™ Particle Size Standards, for calibration and maintenance of Scanning Surface Inspection Systems (SSIS). Available particle sizes correspond to the calibration point sizes required by instrument manufacturers.

8000 Series Silica Particle Size Standards Thermo Scientific™

Provide greater durability and chemical stability when using solvents with Thermo Scientific™ 8000 Series Silica Particle Size Standards, monodisperse silica microspheres used in instrument calibration and as spacers. Standards are calibrated and certified with NIST™ traceable mean diameters and are suitable for a wide variety of particle measurement applications.

ChromoSphere™-T Certified Size Standards Thermo Scientific™

Achieve high visual contrast with Thermo Scientific™ ChromoSphere™-T Certified Size Standards, colored polymer microspheres with NIST™-traceable diameters. These reference and calibration materials are used in the testing of filtration systems, vial cleaning evaluations, contamination control studies and calibration of injection devices.

3000 Series Nanosphere™ Size Standards Thermo Scientific™

Conveniently check the sizes of bacteria, viruses, ribosomes and sub-cellular components with Thermo Scientific™ 3000 Series Nanosphere™ Size Standards, excellent for use with any application that requires a NIST™ traceable size standard with a very narrow standard deviation. The 20 to 900nm range of spheres is ideal for the calibration of electron and atomic force microscopes. Standards are also used in laser light scattering studies and colloidal systems research.

Dri-Cal™ Particle Size Standards Thermo Scientific™

Use Thermo Scientific™ Dri-Cal™ Particle Size Standards for calibrating particle sizing and counting instruments that require dry particles.

4000 Series Monosized Particles Thermo Scientific™

Minimize response of analytic systems to shape effects with Thermo Scientific™ 4000 Series Monosized Particles, excellent for use with any application that requires a NIST™ traceable size standard with a very narrow standard deviation.

Duke Standards™ 2000 Series Uniform Polymer Particles Thermo Scientific™

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.

4D Series Dry Microsphere Size Standards Thermo Scientific™

Calibrate airborne optical particle counters (OPC) to comply with ISO 21501-4 regulations with the Thermo Scientific™ 4D Series Dry Microsphere Size Standards. Ideal for instrument manufacturers, as well as QA/QC managers in pharmaceutical, biotech and electronics manufacturing, these microsphere reference beads feature a calibration uncertainty—the range of values within which the actual mean diameter will lie—that is less than or equal to 2.5% of the mean diameter.
