9000 Series - Glass Size Standards

The  Glass Size Standards are highly uniform Borosilicate or Soda Lime glass spheres calibrated with NIST traceable methodology.  Glass size 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.

The mean diameters of these products have been calibrated with Thermo Fisher Scientific's NIST traceable microscopy methods. Their size distribution and uniformity are measured by optical microscopy. 9000 Series products from 2 µm to 20 µm are made from Borosilicate Glass. Products from 30 µm to 2000 µm are made from Soda Lime Glass.

Spheres are used instead of irregularly shaped particles to minimize the response of analytical systems to shape effects. Products are packaged as dry spheres.

Each package of standards contains a Certificate of Calibration and Traceability to NIST which includes a description of the calibration method and its uncertainty, and a table of chemical and physical properties. A Material Safety Data Sheet, with handling and disposal instructions, is also included. Packages are lot-numbered for convenient technical service and support after the sale.

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.
