Nanoparticle Size Standards
(NIST, SRM, ASTM)

 

Nanoparticle Size Standards are uniform polystyrene spheres calibrated in nanometers (nm) with NIST traceable methodology. A nanometer is one billionth of a meter, 0.001 micrometer (µm, micron) or 10 Angstrom units.

Nanoparticle Size Standards are packaged as aqueous suspensions in 15 milliliter (mL) dropper-tipped bottles. The concentrations are optimized for ease of dispersion and colloidal stability. The spheres have a density of 1.05g/cm3 and an index of refraction of 1.59 @ 589 nm.

Nanoparticle Size Standards are ideal for the calibration of electron and atomic force microscopes. They are also used in laser light scattering studies, and colloidal systems research. The 20 to 900nm range of diameters is also convenient for checking the sizes of bacteria, viruses, ribosomes and sub-cellular components in biology laboratories.
