      A mean size of 9,89µm polystyrene spheres are prepared under gravity-free conditions (Shuttle Columbia). In such conditions, exceptionally uniform spheres are obtained. These spheres can be dispersed over any specimen being examined to provide a reference standard (ASTM certified No. 1960). The size distribution is a narrow Gaussian with a standard deviation of 0.9% (excluding particles not on the main peak). There are some larger particles (less than 1% of the total) which can be excluded from measurement. A statistically significant number should therefore be measured.

      Please note that the certificates covers mean size and does not carry a guarantee of size of any particular particle. Spheres are available in suspension or uncoated and dispersed on a silicon disc. (Disc to be mounted on a stub by user).
