28khz 300W Ultrasonic Mixer Lab Small Homogenizer With Titanium Alloy Probe
RPS-SONIC manufactures the most technologically advanced and reliable ultrasonic processors in the industry for applications such as: dispersion of nanoparticles, nanotubes and Graphene; cell lysing and cell disruption; sample prep; ChIP assay; homogenization; extraction; atomization; and more.
The very high energies produced by cavitation afford a means of creating smaller particle size, and a great many cases allow a reduction n the amount of emulsifying agent. The advantages of Ultrasonic Technology ultrasonic emulsification system Simple,low-cost design----Initial equipment costs area fraction(often one-fourth or one-fifth) of the outlay required for conventional equipment with similar output. Installation of RPS-SONIC emulsification system often merely means the replacement of an existing unit without change of production methods.For example, Ultrasound assisted extraction acts primarily upon the kinetic of the extraction process, and secondarily upon the interfacial area, through the eventual disintegration of larger particles. Compared with maceration, infusion or decoction, it improves the process decreasing both operating time and temperature while increasing the extraction yield. This intensive technique, biochemically safe unless overexposure, was used to obtain active principles with hypoglycaemic activity (sweet diterpenic steviol glycosides) from a medicinal plant with high economical potential: Stevia rebaudiana leaves. Distilled water or a mixture of water and ethanol in several ratios were employed as solvent. The active principles were quantified by HPLC. An Artificial Neural Network was used to model the ultrasound assisted extraction, due to its ability to cope with complex processes and superior generalization capacity
Ultrasonic Preparation of Nanoscale Devices
• Particle size uniformity, strong dispersion, crystal type control, simple preparation, high yield
• Ultrasound nano-fabrication of monodisperse, well-defined nanoparticles and reduced energy consumption
• Ultrasonic nanoprocessing is easier to achieve mesoscopic mixing than conventional mixing techniques, eliminating local concentration variations, increasing reaction rates, stimulating the formation of new phases, inhibiting reunion
Probe sonication is significantly more powerful and effective when compared to ultrasonic cleaner baths for nanoparticle applications. A cleaner bath requires hours to accomplish what a probe Sonicator can do in minutes. Sonicators can create a stable dispersion that can remain in suspension for many months as evidenced in this article excerpt:
Dispersions in vials (a) have coagulated CNTs in the body and at the bottom by means of bath sonication for 8 hours, (b) appear free-homogenous with probe sonication for 3 minutes, and (c) keep free-homogenous even after 4 months of sitting at room temperature. The concentration of Multi-Walled Carbon Nanotubes (MWCNTs) is 2500 mg/L and the MWCNTs/SDS ration is 1:10. (d) MWCNTs of (c) was diluted to 25 mg/L with deionized water.
