Technical Specification Sheet

Branson SFX250 Sonifier w/ 1/2" Horn

  • 20 kHz ultrasonics for quiet tabletop operation.
  • Sample sizes from 0.2 to 500 mL.
  • High-efficiency, handheld and stand-mountable converters require no internal cooling.
  • Scrollable, multifunction screen with pushbuttons.
  • Continuous or pulsed ultrasonics.
  • Amplitude control range from 10 to 100%.
  • Microtip mode limits amplitude to 70% to extend tool life.
  • Control modes include time, temperature, and energy.
  • Advanced energy control mode delivers precise energy input in continuous or pulse modes.

The fully digital control screen allows the user to quickly and effortlessly select control settings, power level, and sonification duration.

The Branson SFX sonifer gives users ultimate control with an amplitute range of 10 to 100% along with continous or pulsed ultrasonics.

These smaller, highintensity tips are ideal for processing smaller samples in Eppendorf vials or similar vessels. Sizes range from 3/32" to 1/4".

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.

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.

With true temperature control (requires separate temperature probe), 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.

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.

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.
