Check Spheres for particle size analysers are an inexpensive particle size standard, designed for daily use to confirm the performance of several types of particle size analyser equipment.

Check Spheres are not designed as a replacement for certified reference materials, but as an inexpensive daily confirmation of instrument performance.

The Check Spheres are supplied at a 1% concentration, which is considerably higher than many certified materials, thus the amount required to carry out the check is less and substantially more checks can be carried out.

Check Spheres are available in a range of discrete sizes from 1µm (micron) to 140um.

The Spheres are manufactured using the Ugelstad-process and are monisized, producing CV’s of less than 3% on the main peak of the distribution.

The spheres can be supplied with a NIST traceable Certificate at an additional cost if required.
