3000 series Nanosphere Size Standards, 20 to 1000 nm

3000 series Nanosphere® Size Standards, 20 - 1000 nm. 3000 Series Nanosphere Size Standards are excellent for use with any application that requires a NIST traceable size standard with a very narrow standard deviation and a very low polydispersion index. Nanosphere Size Standards are ideal for the calibration of electron and atomic force microscopes. They are calibrated in billionths of a meter, nanometers with NIST traceable methodology. One nanometer is 0.001 micrometer or 10 Angstroms.

The smalles sizes are calibrated by Photon Correlation Spectroscopy PCS, 20, 30 and 40nm. The larger sizes are calibrated by Transmission Electron Microscopy TEM. They are also used in laser light scattering studies and colloidal systems research. The 20 to 900nm range of spheres is convenient for checking the sizes of bacteria, viruses, ribosomes and sub-cellular components. Nanospheres are packaged as acqueous suspensions in 15ml dropper/tipped bottles. The package contains a NIST traceable Certificate and a Material Safety Data sheet MSDS.
The concentrations are optimal for ease of dispersion and colloidal stability.
