Description:

  1. Particles of uniform spheres and diameter have long been used as size references to estimate the sizes of other particulates, biomolecules, and living organisms. They can also be utilized to conduct routine calibration and checking of the performance of particle sizing instruments. In addition, QC and validation of analytical methods often depend on them to meet various requirements and regulations. To serve as a size reference, the particle size and size distribution of the monodisperse microspheres are determined by established standard methods. These well characterized size standards have become valuable in applications including microscopy, physical measurement of micron and submicron sizes, study of colloid systems and equipment efficiency.
