Product Overview

The EpiSonic™ 2000 Sonication System is the latest sonication-based instrument with integrated cooling for DNA shearing and chromatin shearing applications. This sonicator is designed for simultaneous, optimized processing of 1 to 12 samples at small microliter-level volumes (optimal at 15 µl of volume), making it an ideal solution for next-generation sequencing due to its high shearing consistency and uniformity.

Features At-A-Glance
The EpiSonic™ 2000 incorporates Digitally Adaptive Sonocavitation™ (DAS) technology to efficiently process DNA and chromatin samples, with the following key features:

  • Simple input and controls
  • Simultaneous sonication of up to 12 samples
  • 10 minutes to shear 12 samples to 300 bp (50 sec/sample)
  • Reproducible and consistent fragments
  • Closed vessel processing
  • Easy installation and maintenance
  • Continuous cooling system
  • 20-month warranty

Key Points
Notable points of the EpiSonic™ 2000 include the following:

  • Generates fragments compatible with IlluminaIon Torrent454, and Pacific Biosciences platforms.
  • Generates tight and highly reproducible fragment distributions.
  • Capable of achieving uniform fragment sizes between 150 bps and 20 kbs.
  • Meets "the scientist's requirements" for a low-cost, flexible, higher throughput and easy-to-use design.
  • Eliminates operator-induced variations, improves recovery yield, increases efficiency, and provides results that can be standardized.

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 2000 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 2000 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 be used with any other applications?
Although the EpiSonic 2000 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 per sample?
0.2 ug of DNA in 15 µl of volume is recommend per processing tube.
