International ClassB02C 019/18Foreign Application Priority Data1988-08-01 JPAbstractDisclosed is an ultrasonic cell-destroyer using cell-suspending solution containers each having a groove at its bottom, thereby causing ultrasonic energy available to converge to the container bottom to increase the efficiency at which cells can be destroyed in the cell-suspending solution. The ultrasonic cell-destroyer may use a rotary container holder, which is capable of rotating a plurality of containers in the bath to evenly expose all the containers to ultrasonic wave. | |
