Particle size distribution of unfiltered particles in H2O and cell culture medium. Coulter Counter analysis showing number concentration (No. Conc.) and volume concentration (Vol. Conc.) of particles dispersed in F-12 K (corundum, Quartz DQ12, composite particles) and for double destilled H2O (composite particles only). Note that size maxima shift of the number concentration peaks shift to larger values except for Z100 MP and Tetric EvoCeram
