Utraschall-Thema: "What are Ultrasonic Extractors Used for?"

Ultrasonic extractors are the superior tool when it comes to the intensification of ultrasonic extraction processes. As a non-thermal method, sonication prevents the degradation of temperature-sensitive substances (e.g. vitamins, flavours, antioxidants, CBD etc.). The application of high-power ultrasound waves causes the perforation and disruption of cells and tissues and promotes mass transfer. This means the intracellular material (i.e. the targeted substances) is released from the inner cell and transferred into the solvent. Ultrasonic extraction intensifies the extraction process resulting in higher yields, superior extract quality and rapid processing. At the same time, ultrasonic extraction is an environmental-friendly, green method. Read more about how sonication can improve your extraction process!

Utraschall-Thema: "How to use ultrasonicators"

Ultrasonicators are ultrasonic probe-type devices, which are used for manifold applications including homogenization, dispersing, wet-milling, emulsification, extraction, lysis, disintegration, and chemical reactions. The working principle of an ultrasonicator is based on the phenomenon of acoustic cavitation. When intense ultrasound waves are coupled into a liquid, alternating high-pressure / low-pressure cycles travel through the liquid. During the low-pressure cycles, the ultrasonic waves create minuscule vacuum bubbles, which grow over several pressure cycles. When the vacuum bubbles reach a volume at which they cannot absorb further energy, they implode violently during a high-pressure cycle. Briefly, cavitation is the growth and collapse of vacuum bubbles or cavities. During the bubble implosion, an exceptionally energy-dense field is created. In an acoustic cavitation field, extreme conditionsincluding very high temperature and pressure differentials, turbulences, shear forces and liquid jetscan be measured. These intense cavitational forces are used to fulfil the manifold applications mentioned above. Ultrasonicators create cavitation to apply it purposefully to

Lysis is the term which describes the disruption of cell walls or membranes. Ultrasonic disruptors are a reliable tool to break cells in order to release intracellular compounds such as DNA, proteins, organelles, and phytochemicals. For ultrasonic lysis (aka cell disruption), high-intensity / low-frequency ultrasound waves are applied to disrupt the cell membranes. Since ultrasonication promotes mass transfer, the intracellular material is released into the surrounding solvent. The fluid containing the contents of lysed cells is called a lysate. Cell lysis is the first step in cell fractionation, organelle isolation and protein extraction and purification. Read more about ultrasonic cell disruptors and ultrasonic lysis!
