Preliminary information suggests that plant and animal tissue can be disrupted more quickly with sharp-edged material rather than smooth beads.
The sharp, hard edges of these irregular particles impart a knife-like cutting action during high-energy shaking in Mini-Beadbeater vials. They may abrade and micro-chop tough tissue faster than beads. For softer tissues beads are preferred. These beads are dusty. Wash with lab detergent before first use.
