The Bioruptor® sonication devices use a unique system to uniformly process multiple samples simultaneously in sealed tubes of 0.5 ml to 50 ml capacity. It consists of a high power ultrasound generating element which is located below a water bath. The frequency of the ultrasound energy produced by the Bioruptor® is 20 kHz, which is similar to a probe sonicator. The Bioruptor® allows you to sonicate 6 to 48 sealed tubes simultaneously without aerosol formation improving biosafety (e.g. Mycobacterium, Viruses, etc.). The continuous sample rotation guarantees equal distribution of the energy and therefore 100% reproducible results. The parameters can be efficiently controlled and allow for the automation of the sonication step in your experiments. The Bioruptor® is easy to setup and uses standard disposable containers (PCR tubes, Eppendorf, 15 ml and 50 ml Falcon/Corning tubes). Validated protocols (e.g. ChIP, MeDIP etc.) can be standardized and transferred between labs.

What are the effects of ultrasound on biological samples?

High powered ultrasound waves can produce gaseous cavitation in liquids. Cavitation is the formation of small bubbles of dissolved gases or vapors due to the alteration of pressure in liquids. These bubbles are capable of resonance vibration and produce vigorous eddying or microstreaming. This mechanical stress has multiple effects on biological samples including; effective cell lysis, DNA and chromatin shearing as well as homogenization. When using a probe sonicator, the microstreaming phenomenon is limited to the vicinity of the probe which can generate high amounts of heat and release metal fragments. In contrast, the Bioruptor’s water bath is equally exposed to ultrasound energy allowing for the dissipation of heat and providing uniform absorption of energy.
