Ultrasonic topic: "Ultrasonically-Assisted Emulsification"
Emulsification involves the process of mixing two immiscible liquids, such as oil and water, to create a stable mixture where one liquid is dispersed as tiny droplets within the other. The ultimate goal is to achieve a uniform dispersion with droplets small enough to remain stable over time, preventing the separation of the two liquids.
Sonication is an important technique for nano-emulsification, which refers to the creation of emulsions with droplet sizes in the nanometer range. Sonication is particularly effective for nano-emulsification because it can achieve extremely fine droplets without the need for high concentrations of surfactants or extensive mechanical mixing, making it a preferred method in applications where ultra-fine emulsions are required, such as in pharmaceuticals, cosmetics, and food products.
Hielscher’s sonicators and ultrasonic reactors provide high-performance ultrasound to obtain high-quality emulsions. Learn more about our ultrasonic systems and ultrasonically-assisted emulsification!

Ultrasonic Emulsifiers
An emulsion is a two-phase system of two immiscible liquids, where one phase, the so-called internal or dispersed phase, is distributed as small droplets into the other, so-called external or continuous, phase. To prepare an emulsion, generally energy input into…
