    Mechanical methods of cell rupture include ball mills, blenders, French presses, homogenizers, and ultrasonic disruption. Ultrasonic disruption is often used in the laboratory with yeast and bacteria, but it is too expensive to use on a larger scale. Blenders and French presses are easy to use in the laboratory, but cannot be readily scaled up
