Utrasonic topic: "How to use Ultrasonic Reactors"
Ultrasonic reactors are used for manifold applications to homogenise and disperse nano materials, to extract bioactive substances and to initiate chemical reactions (sonochemistry). Since sonication is a highly efficient process intensifying technology, ultrasonic reactors are used in chemistry and material science, the production of biodiesel and aqua-fuels, and in the food, pharma and cosmetic industry.
Ultrasonic chemical reactors are available for laboratory and industrial. Learn more about the applications of ultrasonic reactors and their easy integration!

In order to increase production capacities, extraction processes must be scaled to larger volumes / higher throughputs. Ultrasonically-assisted extraction is a highly efficacious method to isolate botanical compounds from plant material. Additionally, sonication applications can be linearly scaled to larger…https://www.hielscher.com/scale-up-of-ultrasonic-extraction-processes.htm
Ultrasonic mixing is the superior technology for highly efficient and cost-effective biodiesel production. Ultrasonic cavitation improves mass transfer drastically, thereby reducing production costs and processing duration. At the same time, poor-quality oils and fats (e.g., waste oils) can be used…https://www.hielscher.com/superior-process-and-cost-efficiency-in-biodiesel-production.htm
Phosphorus is a critical resource mineral, which natural supply is diminishing rapidly. Consequently, the German government enacted by decree that from 2029 phosphorus must be largely recovered from sewage sludge. The implementation of power ultrasound opens various options to intensify…https://www.hielscher.com/various-solutions-for-phosphorus-recovery-from-municipal-sewage-sludge.htm
Ultrasonication is well known to intensify and/or initiate chemical reactions. Therefore, the integration of high-performance ultrasound is considered as reliable tool to promote chemical reactors for improved reaction outcomes.
