Intense sonication of up to 10 vials simultaneously.
DNA released was extracted two times with a phenol: chloroform: isoamyl alcohol mix,and afterwards subjected to second sonication for 0- 15 min.
This makes your sonication runs comparable and reproducible.
For the ultrasonic extraction, 5 g of the pulverised freeze-dried Kratom leaves are placed in a beaker containing 200 mL of CHCl3:CH3OH, 1:4(v/v),which is placed in an ice bath to keep the temperature during sonication low.
The O/W emulsion was prepared viamagnetic stirring for 1 h followed by sonication with an UIP1000hd equipped with ultrasonic horn(probe/ sonotrode) for another 30 min in the ice bath.
Under intense sonication, 33% of the added Q2+ containing 45.2% of Q(Ph(OH)COO)2 has transferred into the organic phase to react with benzyl bromide, hence the overall reaction rate was enhanced.
All experiments were performed on samples(10 g barley seeds)dispersed in 80 mL of tap water with direct sonication(probe system) at a power input of 20, 60, and 100%, with additional agitation or shaking.
Sonication was performed in methanol-water(80:20, v/v) mixture at 46°C with a solid to solvent ratio of 1:26, w/v and resulted in an increased charantin yield of more than 3 mg/g charantin from bitter gourd powder.
Since the first trials willnot be run at optimum configuration, sonication intensity and time by 10 to 50 times of the typical value will show if there is any effect to the sonicated material or not.
If an application requires even higher amplitudes and/or very high temperatures, Hielscher offers customized ultrasonic sonotrodes, which can deliver amplitudes ofgt;200µm andinserted into very hot environments(e.g. for sonication of metal melts).
The shift in dominant mechanisms for sonication of metal powders versus aspirin slurries highlights the differences in properties of malleable metallic particles and friable molecular crystals.“[Zeiger/ Suslick 2011, 14532].
Equipped with a colored touch screen, integrated LEDs for sample illumination, pluggable temperature sensor, integrated SD-Card for data record, and many other features,the UP200St turns into a user-friendly and reliable tool for efficient and precise sonication.
For the extraction of pomegranate, sonication helps to isolate ellagitannins, ellagic acids, pomegranatate, punicanolic acid(a type of triterpenes found in essential oils) and many other antioxidants, vitamins and polyphenols.
The mechanical shear forces of ultrasonic tissue homogenization can be adjusted precisely to the specific material, either very soft tissue preparation(e.g. for DNA/ RNA)by mild sonication or destructive cell disruption(e.g. for nannochloropsis, yeast) by intense ultrasonic cavitation.
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.
They used Quillaja wood and bark chips andextracted the saponins in water using sonication, so that the final product only incorporates natural ingredients and raw materials and could be used in food manufacturing processes.
Since the ultrasonic emulsification process can be precisely controlled, ultrasonic emulsification and the subsequent process of forming solid-lipid nanoparticlesis capable to produce loaded nanoparticles sonication can produce significantly lower droplet sizes in comparison to conventional emulsion methods.
The VialTweeter is an effective alternative to the sonication of vials in ultrasonic cleaning baths or tanks, in which the water surrounding the vials takes most of the energy- while the effective power in a 1.5ml vial is as low as 0.01 watt.
Sonication with a powerful ultrasonicator(e.g. UIP2000hdT) causes significant changes in conductivity, increases the solubility of soy protein concentrates, increases the specific surface area significantly, which is important for food textures, and increases the values of the emulsion activity index(EAI).
Hielscher Ultrasonics manufactures various ultrasonic lab homogenizers such as hand-held and stand-mounted devices, the VialTweeter for the simultaneous indirect sonication of up to 10 vials without cross-contamination or the SonoStep, a sample prep unit which combines sonication, stirring and pumping in one compact system.
For an improved and more convenient sonication, Hielscher Ultrasonics offers his existing customers the opportunity to upgrade their ultrasonic processors of the hd-series to the new hdT-standard, which is characterized by touch control and various features.
Besides the production of cold-pressed high-quality edible oils, sonication can be applied to the downstream processing of the avocado oil, e.g. by emulsifying the avocado oil with water-based components for salad dressings, sauces or even cosmetic products.
These features make sonication an attractive proposition for many extractions and for scale-up it should be used in the extraction unit itself where the plant material is in direct contact with the solvent e.g. in the extraction of antioxidants from Rosemary.
