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.
About Whitehouse Scientific
Whitehouse Scientific is a leading producer of glass microspheres for calibration and is the highest ranking European certification laboratory for primary methods of particle size analysis. The company's standards cover all particle sizing techniques including laser diffraction, Coulter methods, optical sizing, sieve calibration and image analysis. Most of these reference materials are NIST-traceable. They range in size from 0.1 micron to 5.0 millimetres and are available as single sizes or broad distribution standards. In addition, Whitehouse offers a unique calibration procedure for NIST-traceable measurement of filter apertures between 3 and 1000 microns, and also produces general purpose research grade microspheres.
Whitehouse Scientific has been producing calibration microspheres for more than 25 years. Founder and managing director Dr Graham Rideal is a past chairman of The Filtration Society, and is now active as its Science Correspondent. He is a member of the 'Editorial Advisory Board' for Filtration News Magazine, USA.
