NIST traceable standard microspheres and
nanospheres are exceptionally monodisperse particles made of silica.
Currently offered range
for nanospheres 50-1000nm and for microspheres 1-100µm
(total of about 80 products) making them suitable for most particle-based
These microspheres and nanospheres are
traceable to standards from the national Institute of Standards and
Technology (NIST). The have been measured using well calibrated particle
These microspheres and nanospheres provided in an easy-to-dispense format
are supplied as a 1.0% solids aqueous dispersions in 10 ml dropper tipped
Our microsphere and nanosphere size standards useful in in many areas of
research and development, as well as industrial applications for quality
and process control, where the size and size distribution is important.
There are may methods to measure the size of objects below 100 micron,
however, these systems should be calibrated against standards, where the
precise size of microparticles and nanoparticles are important. Examples
of such areas are biological applications to determine the size of
viruses, bacteria and cellular components; pharmaceutical industry;
ceramics, powders, clays, pigments, abrasives, polishing compounds, soils
Other size standards based on
latex are also available.
