Nanosphere Size Standards are highly uniform sulfate particles calibrated in billionths of a meter(nanometers) with NIST traceable methodology.One nanometer is 0.001 micrometer (μm) or 10 Angstroms.
Nanosphere Size Standards are ideal for the cali-bration of electron and atomic force microscopes.
They are also used in light scattering studies and colloidal systems research. The 20 to 900 nmrange of diameters is convenient for checking the sizes of bacterial, viral, ribosomal and sub-cellular components.
Nanospheres are packaged as aqueous suspen-sions in 15 milliliter (mL) dropper-tipped bottles.The concentrations are optimized for ease of dispersion and colloidal stability. The spheres have a density of 1.05 g/cm 3 and an index of refraction of 1.59 @ 589 nm (25 °C)
