The Mixer Mill MM 400 can be used to easily homogenize the sputum sample; however, since 2 ml vials were used in the past, it was not feasible to process more than 1 ml of each sputum sample. It was not an appropriate procedure to divide the viscous and tough sputum into portions for homogenization as it is a partly infectious material.

Cell Disruption: Sonication vs. Homogenization

Bead-based homogenization uses plastic or metal beads combined with high-speed shaking to create shearing forces. This technique is well-suited to whole animal, insect (e.g., Drosophila melanogaster) or plant specimens, which requires disruption of sturdy cell walls.A drawback of bead-based disruption is that it requires the proper selection of bead material and diameter.
