QM100 high throughput tissue mills_Laboratory grinding ...

Ball milling using a plurality of small-diameter grinding can greatly improve the mixing of the sample. Biological cells can be by using a large number of small balls (e.g., glass beads) for cell disruption. Tremendous impact and friction between the ball and the cells can be achieved efficiently broken.
