Following the success of the 9um glass microsphere standard, Whitehouse Scientific has introduced a range of monosized silica microspheres - from 10um down to 1.5um.
Using a highly specific microscope certification procedure, all the silica standards are traceable to NIST and NPL international standards of length.
They are available in sets of 10 bottles, each containing 0.2 g of dry powder, either all the same size or as a mixed set as specified by the user.
A certificate of analysis is enclosed.
Applications of the silica microspheres include filter testing, spacing applications and as respiratory or drug-delivery models for the pharmaceutical industry.
