Garnet sharp particles are sold in one pound bottles. Average size +/- 20%
Like Silicon Carbide sharp particles, these abrasive particles have sharp cutting edges that may accelerate lysis of plant and tough animal tissue in a Mini-Beadbeater vial.
Unlike Silicon Carbide particles, Garnet particles break down to smaller size particles during the grinding process. This may be an advantage if you are wanting to lyse not only eukaryote cells but also microbial cells in the sample. However, for the same reason, garnet particles should not be used in a tissue preparation if the goal is to recover intact intracellular organelles or viable microbial cells.
NOTE: Garnet Particles should not be used with the BeadBeater 1107900.
