Overview. Designed for low-volume applications, the SFX150 Sonifier® delivers up to 150 watts of power at 40 kHz for quiet operation. It’s the only cell disruptor and homogenizer of its type that includes a handheld converter designed for ergonomic comfort and easy control to simplify and speed your experiment. The recessed pushbutton helps prevent unintended activation, while the LED indicator light lets you know when it’s energized. A conventional converter and stand can also be used, and the SFX150 includes all the same control and monitoring functions as the SFX250 and SFX550.
