New Monosized Silica Microspheres



Chester, UK: Following the success of the 9 micron glass microsphere standard, Whitehouse Scientific has introduced a new range of Monosized silica microspheres from 10 microns down to 1.5 microns.

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.
