Ultrasound to emulsify and disperse liquids
A lot of consumer products, like milk, cremes, cosmetics, and pharmaceuticals are based on emulsions, which are
disperse liquid-liquid systems of two or more insoluble liquids. Nanomaterials are often used additives to functionalize products. As nano particles are mostly quite cohesive, a efficient method of mixing, dispersing and deagglomeration is required. Ultrasonic cavitation forces are a powerful method of processing micro- and nano-sized materials.

High energy is needed to disperse liquid phase (dispersed phase) in the form of small droplets in a second phase (continuous phase).
Hielscher manufactures ultrasound devices and accessories for a highly efficient emulsification and dispersing of liquids.
With lab devices of up to 400W power and industrial ultrasonic processors of up to 16000W power, Hielscher says it is the leading ultrasonics manufacturer worldwide.
Hielscher ultrasonic devices require a very low maintenance and are easy to operate and simple to clean, it says.
Bench top equipment is available for rental at good conditions to run process trials.
Results of such trials can be scaled linear to production level - reducing the risk and costs involved in the process development.
