Mechanical Disruption Methods: Grinding
For simplicity, the methods used for sample disruption have been divided into four groups: grinding, shearing, beating, and shocking. Many engineers may cringe by this delineation, but we are approaching the topic practically and as biologists. Foremost, it must be highlighted that many methods make use of more than one force, as with conical homogenizers which grind and shear. We attempt to
