With various speed controls for precise modifications, different viscosity substances that normally would be ordinarily immiscible can be successfully emulsified. The frequency-driven tools control blending conditions and are straightforward to operate. With ergonomically located buttons for RPM readout and sealed membrane, dispersing tools are designed for user comfort.
