Place the vials into a high through put homogenizer, such as a HT Homogenizer or GenoGrinder . Vials can be placed in racks or in a vial sets (up to 24 to 48 samples per run, depending on the homogenizer). Homogenize at 1500 rpm for five minutes. Remove the vials and examine the contents. If small pieces of nail remain, repeat the process.
