Specific embodiment

First aspect described herein is a kind of ultrasonic processing apparatus, for in the sample with essentially round side wall The biological sample for including in pipe is ultrasonically treated, which includes:

Sample tube rack is pivotly suspended in corresponding support, allows the sample tube rack in the vertical direction It is rotated around x-axis, which is the rotation axis that pivot defines, and wherein the sample tube rack is configured as not having The sample cell is kept in the vertical direction along z-axis line in the case where having rotary motion, which is substantially parallel to gravity Direction and perpendicular to the x-axis, and wherein the sample tube rack includes the opening towards at least side;

Supersonic generator comprising for ultrasonic wave to be applied to the sonication areas of the sample cell, at the ultrasound Reason region includes concave surface and installs in height identical with the pivot in itself, and the x-axis is substantially in the ultrasonic treatment In the height at the vertical center in region, wherein the supersonic generator is mounted on for along perpendicular to the x-axis and the z-axis line Y-axis towards or away from the guide rail of the mobile supersonic generator of the sample tube rack, wherein the sample tube rack should Support is fixed to one end of the guide rail, and wherein the opening of the sample tube rack is towards the sonication areas, so that in super The sonication areas of sonication position and the side wall of the sample cell in the sample tube rack are physically contacted;

Actuator is used to move ultrasonic wave generation on the guideway relative to the sample tube rack along the y-axis Device.

This ultrasonic processing apparatus enables a technician to optimize from supersonic generator to the biology in counter sample pipe The transmission of the ultrasonic energy of sample, to effectively handle it, such as to crack the strong cause of disease of such as mycobacteria Body simultaneously discharges its biochemical content object, such as nucleic acid.
