WebThe smallest microspheres are currently about 0.02 µm in diameter, with a coefficient of variation (CV) of about 20% as determined by electron microscopy. The size uniformity improves with increasing size, with the CV decreasing from ~5% for 0.1 µm FluoSpheres beads to ~1% for those with 10–15 µm diameters. Dispensing of microspheres can be a difficult task. When utilizing microspheres as a filler for standard mixing and dispensing machines, a breakage rate of up to 80% can occur, depending upon factors such as pump choice, material viscosity, material agitation, and temperature. Customized dispensers for microsphere-filled materials may reduce the microsphere breakage rate to a minimal amount. A progressive cavity pump is the pump of choice for dispensing materi…
