The Sonifier® induces cell disruption, homogenization, and emulsification through cavitation (the rapid formation and collapsing of vapor bubbles), created by ultrasonic vibrations. The converter transmits vibration through the horn and into the sample. The ultrasonic vibrations transmitted through the horn can be applied directly or indirectly to samples, using a variety of specifically designed horns, tips, and chambers.

The SFX250 and SFX550 are part of the new SFX Series of Sonifiers from Branson, designed to bring the industry’s most advanced sample-processing capabilities to your laboratory. The SFX Series brings a new level of ease, precision, and repeatability with advanced energy and temperature control modes, process monitoring capabilities, and programming features.

Each Sonifier is supplied ready-to-use and includes a power supply, a converter, and a 1/2" tapped step horn (a 3/4" horn is optional with the SFX550). The power supply/converter changes standard electrical power to high frequency mechanical energy which is then applied to the horn where it is further amplified for use.

 Sonifier SFX250 Model

  • 250 watts of power at 20 kHz
  • Processes samples from 0.2 up to 500 mL
  • Includes power supply, converter and 1/2-inch disruptor horn

Sonifier SFX550 Model

  • 550 watts of power at 20 kHz
  • Processes samples from 0.2 up to 1000 mL
  • Includes power supply, converter and 1/2" or 3/4" disruptor horn

All SFX Series Sonifiers feature a digital, intuitive interface flanked by easy-to-use push-buttons. The screen and buttons provide one-touch access to all control parameters and modes of operation.

  • Advanced control modes. In Energy Mode, the SFX Series power supply manages the processing cycle to deliver a precise, user-determined input of ultrasonic energy (measured in joules), either continuously or pulsed. The SFX Series automatically compensates for any variability, extending or shortening the cycle as needed to deliver the precise energy output.
  • True temperature control. (Requires separate temperature probe.) With true temperature control, the SFX Series power supply maintains the temperature of the sample to within a user-specified range, automatically adjusting the ultrasonic pulse length to regulate the temperature rise and prevent overheating.
  • Sample-processing programs. For assured repeatability and precision on a greater scale, the SFX Series enables users to create and store up to 20 sample-processing programs. Program parameters include continuous or pulsed ultrasonics; time, energy, or temperature control modes; pulse on-time/energy, off-time, and total on-time/energy; or amplitude as a percentage.
  • Process monitoring. In operation, Sonifier SFX Series monitors ongoing processes on a scrollable, digital screen, providing continuous updates of key variables including power level, energy usage, sample temperature, and experiment progress.


  • Advanced energy control mode delivers precise energy input in continuous or pulse modes.
  • True temperature control manages sample temperature within user-specified limits
    (requires separate temperature probe).
  • Control modes include time, temperature, and energy.
  • Continuous or pulsed ultrasonics.
  • High efficiency, stand-mountable converter requires no internal cooling.
  • Scrollable, multi-function screen with pushbuttons.
  • In-process feedback displays experimental progress together with key variables such as
    power level, energy usage, and sample temperature.
  • Microtip mode limits amplitude to 70% to extend tool life.
  • Amplitude control range from 10 to 100%.
  • Powerful 20 kHz ultrasonics.
  • Up to 20 stored programs. Programmable parameters include continuous or pulsed ultrasonics; time, energy, or temperature control modes; pulse on-time/energy, off-time and total on-time/energy; or amplitude as a percentage.

Please note: All Sonifiers are manufactured to order and have a 1 week lead time.
