3000 Series - Monodispersed Beads

Highly uniform polystyrene spheres calibrated within a 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 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.
