Monosized microsphere size standards 1 - 1000um

These highly uniform polystyrene spheres are calibrated by NIST standardised methods which include photon correlation spectroscopy, transmission electron microscopy and light microscopy.

These highly uniform polystyrene spheres are calibrated by NIST standardised methods which include photon correlation spectroscopy, transmission electron microscopy and light microscopy. The range of diameters from 1 to 1000µm is ideal for the calibration of electron microscopes, optical microscopes and particle sizing instrumentation. A certificate of calibration and traceability is provided with each standard. Detailed physical and chemical properties are also provided.

They are some of the most uniform spheres available in this size range. Products from 1 to 160µm are packaged as 15ml aqueous suspensions in dropper topped bottles. Diameters of 200µm and larger are packaged as 1g dry spheres. The spheres have a density of 1.05g/cm3 and a refractive index of 1.59 @ 589nm wavelength.
