Product Details

Technological Advantages
Several new aspects have been introduced since the earlier 1000 model to enhance the performance of the EpiSonic.

  • The internal circuitry has been modified to apply DAS™ technology to allow for further precision and reproducibility
  • The redesigned, double-concave shaped sample processing horn causes piezoelectric vibration to propagate more evenly through the entire liquid medium (water) within the reservoir so that acoustic energy/mechanical stress is equally transmitted into samples located in different positions
  • A new vessel rack is conveniently included for pre-optimized operation with sample position consistency and run-to-run reproducibility
  • The included, new recirculating chiller promotes an isothermal environment to maintain the integrity of sensitive samples and prevent thermal degradation
  • Better optimized protocols included to shear DNA into various lengths for ideal compatibility with library preparation in next generation sequencing platforms from Illumina, Roche, and Life Technologies

Proven Precision, Consistency, & Reproducibility
The EpiSonic 1100 has been extensively tested and optimized for shearing samples in a precise, consistent, and reproducible manner. Desired sample sizes are able to be achieved due to the digital precision of the amplitude controls by allowing for user adjustment in intensity intervals of 1% at a time [Fig. 2]. Furthermore, samples placed in different positions with the included vessel holder (Tube Rack) are able to maintain consistency and equal sizes between each other [Fig. 3]. Most importantly, samples are sheared in reproducible lengths between the first run and the next run, creating predictable results and eliminating optimization time and labor [Fig. 4].

The Working Principle
The technology that drives the EpiSonic 1100 so well is Digitally Adaptive Sonocavitation™ (DAS), a principle that is ideal for shearing DNA or chromatin as well as for lysing cells and tissues. During the DAS process, the electronic signal produced by a digitally-controlled generator is converted into acoustic/mechanical energy through a piezoelectric converter (also known as a transducer). When the acoustic energy is produced in water, negative pressure is generated and causes the distance between the water molecules to exceed the maximum molecular distance necessary to hold liquid intact. Consequently, the liquid breaks down to create millions of cavitation bubbles.


These cavitation bubbles expand in size through several acoustic cycles as more acoustic energy is introduced. The size of the cavitation bubbles and the corresponding cavitation energy can be manipulated and digitally controlled by adjusting fully scaled amplitude levels (1-100% in intervals of 1%) with a DAS™-based device such as the EpiSonic 1100. When the acoustic energy is suddenly removed, these cavitation bubbles collapse, creating intense shock waves in an extremely short period of time (microseconds), which transmit into vessels containing samples. This in turn forms highly targeted shearing forces to break up or disperse biomolecular samples including DNA, chromatin, and tissues in a non-contact, non-invasive manner. In a nutshell, a DAS™-based device such as the EpiSonic 1100 is able to shear samples with more precision and reproducibility than non-DAS™ instruments.

Compatible Sequencing Platforms
The EpiSonic 1100 can shear high quality DNA into any size under 2000 base pairs, which essentially covers all next-generation sequencing devices that require DNA library preparation. To be specific, some of the popular platforms that are compatible include the following:

  • Illumina Genome Analyzer
  • Illumina HiSeq
  • Illumina MiSeq
  • Roche 454 Sequencing GS FLX
  • Roche 454 Sequencing GS Junior
  • Life Technologies SOLiD System
  • Life Technologies Ion Torrent

Frequently Asked Q's

What is ultrasonics?
Ultrasonics, or ultrasound, literally means beyond sound -- sound above the human audible spectrum. Standard ultrasonic processors or sonicators operate at a nominal frequency of 20 kilohertz (kHz) or 20,000 cycles per second (cps). The automatic tuning feature of the EpiSonic 1100 actually moves the frequency within a small range during operation to optimize performance. The ultrasonic energy can then be converted by a pziezoelectric converter/transducer into acoustic energy to cause liquid cavitation through mechanical vibrations.

Why does the EpiSonic operate at 20kHz?
At lower range frequencies (20kHz to 100kHz), large cavitation bubbles are produced -- the collapse of which causes extreme hydraulic shearing forces and effects. Digitally Adaptive Sonocavitation™ (DAS), a 20kHz principle, allows for the size of the cavitation bubbles and the corresponding cavitation energy produced at low acoustic frequencies to be digitally controlled by dynamic amplitude adjustments of 1% to 100%. Therefore, DAS™ is more suitable for generating controllable shearing forces to break up cells and macromolecules such as DNA and chromatin in a non-contact, precise, and reproducible manner.  

What are the differences between the lower frequency Digitally Adaptive Sonocavitation (DAS) and higher frequency mechanisms for acoustic-based sonication?
DAS™ operates at 20kHz to cater to users who desire flexibility in being able to powerfully shear samples at fast speeds as well as to precisely shear samples at slower speeds. In frequencies of levels higher than 20kHz (e.g., medium frequency range of 100kHz to 1000kHz such as Adaptive Focused Acoustics™ or AFA), there is less time for the cavitation bubbles to grow. This unfortunately results in smaller bubbles and a corresponding reduction in cavitation energy with increased wait times to effectively shear samples. 100kHz to 1000 kHz frequencies are instead better suited for submicron particle removal and often used for breaking up the structure of organic compounds such as chlorophenol, TBT, and MTBE. Higher frequency sonication does not generally hold any advantages over standard 20kHz frequency sonication for shearing DNA or chromatin. The DAS™ technology of the EpiSonic 1100 provides maximum versatility by combining the powerful shearing forces of 20kHz frequency with digitally precise amplitude controls to finely adjust the intensity of such forces.

Can the EpiSonic 1100 be used with any other applications?
Although the EpiSonic 1100 was specifically designed and supported for DNA shearing, chromatin shearing, and cell disruption/lysis, it is capable of disaggregation, homogenization, cleaning, mixing, degassing, dispersion, cleavage, catalyzing reactions, hydrolyzation, extraction, dissolution, emulsification, comminution, synthesis, microencapsulation.

What kind of volume sizes can be used with the EpiSonic 1100 per sample?
The 0.2ml tube rack is included as standard for up to 60 µl of sample content per PCR tube (15 µl optimal). A 96-well plate rack is also offered as an optional accessory for plates at up to 60 µl of sample content per well (15 µl optimal). The unit is also capable of handling 1.5ml microtubes.
