NIST Traceable Size Standards

NIST Traceability

Particle Size Standards provide third party traceability to national and international agencies through an unbroken chain of measurements with specified uncertainties.  Our products can also help develop and test new analytical instruments for particle size characterization of materials.

Technical Support

Our experienced technical staff come from many scientific disciplines.  We integrate our knowledge and experience into powerful solutions and proven problem-solving for our customers.  Any questions? Send us an E-mail

Prove traceability of analytical methods

Certified Particle Size Standards are traceable to the Standard Meter through the National Institute of Standards and Technology (NIST).  This feature enables laboratories to demonstrate the traceability of their analytical methods as required by ISO 9000, ISO 10012, ANSI/NCSL Z540, GMP/GLP and other standards and regulations. 

Nanospheres

Our Nanosphere products are highly uniform spheres calibrated in billionths of a meter with NIST traceable methodology.  One nanometer is 0.001 micrometer (µm) or 10 Angstrom units.

Product Traceability

A long history of batch and packaging records permit servicing of products of any age. 

Custom Products

Custom products are available in a choice of dyes, diameters, surface groups and fill volumes.  Any questions? Send us an E-mail
