Description The 9000 Series is available as uniform particles of borosilicate or soda lime glass in a range of discrete sizes from 2 µm to 2000 µm. Calibrated and certified with NIST traceable mean diameters, they are suited for particle measurement applications. They also have a better tolerance to chemicals and solvents, and a higher mechanical and thermal stability.
Material Soda Lime Glass
For Use With (Application) Narrow Size Standard Deviation Applications
Composition Soda Lime Glass
Additive None
Particle Density 2.4 to 2.6g/cm³
Includes Certificate of Calibration and Traceability to NIST

The Glass Size Standards are highly uniform borosilicate or soda lime glass spheres calibrated with NIST-traceable methodology. Standards are ideal for the calibration of microscopes, light scattering instruments and other particle-measuring equipment. They are also used in laser light scattering studies and colloidal systems research.
  • Mean diameters have been calibrated with Thermo Fisher Scientific™'s NIST™-traceable microscopy methods
  • Size distribution and uniformity are measured by optical microscopy
  • Spheres are used instead of irregularly shaped particles to minimize the response of analytical systems to shape effects
  • Products are packaged as dry spheres
  • Packages are lot-numbered for convenient technical service and support after the sale
  • 9000 Series products from 2μm to 20μm are made from borosilicate glass, have a particle density of 2.5 to 2.55g/cm3 and an index of refraction of 1.56 at 589nm (25°C)
  • Products from 30μm to 2000μm are made from soda lime glass, have a particle density of 2.4 to 2.5g/cm3 and an index of refraction of 1.51 at 589nm (25°C)


Certificate of Calibration and Traceability to NIST™, including description of the calibration method and its uncertainty, table of chemical and physical properties, and Material Safety Data Sheet with handling and disposal instructions.

Recommended for:

Spacer applications where uniform bond thickness is a necessity.


Thermo Fisher Scientific™ has its own engineering, production and metrology facilities for better quality control and response to customer needs. In addition to this line of polymer size standards, we also offer calibration standards in silica and glass materials.
