Description
– Nanosphere Size Standards are highly uniform polystyrene spheres calibrated in billionths of a meter (nanometer) with NBS traceable methodology.
– Nanosphere Size Standards are used in the calibration of electron microscopes, aerosol and liquid particle studies, chromatography columns, and laser light scattering studies. The 20 to 1000 nm range is suitable for checking the size of bacteria, viruses, ribosomes and sub-cellular components. Nanosphere Size Standards are packaged as aqueous suspensions in dropper-tipped bottles.
Specific gravity :1.05g/ml R
Refractive index of 1.58 @ 589nm (25°C).
