Intense Sonication of Vials.
Ultrasonic cup horn TD_CupHorn for intense sonication.
Intense sonication of up to 10 vials simultaneously.
Ultrasonic cup horn TD_CupHorn for intense sonication from different angles.
The intense sonication helps to disperse agglomerated particles leading to more consistent results.
Alternatively, the UIS250v can be used for the very intense sonication of one single vial.
This intense sonication produces nano-particulated slurries for fast setting rates and superior gypsum products.
Demanding processes- such as refining of metal melts-require the capability of intense sonication.
When samples aresonicated using an ultrasonic probe device, the intense sonication zone is directly beneath the sonotrode/ probe.
Under intense sonication enzymes or proteins can be released from cells or subcellular organelles as a result of cell disintegration.
Amplitude and processing intensity can be precisely adjusted andcontrolled from very mild to highly intense sonication conditions.
Intense sonication of liquids generates sound waves that propagate into the liquid media resulting in alternating high-pressure and low-pressure cycles.
For this, a small sample volume, e.g. 5mL is put into a small vial andis being exposed to intense sonication for a long time.
The acoustic cavitation generated by intense sonication creates energy-dense conditions such as high pressure and temperature differentials as well as high shear forces and turbulences.
However, the most important fact is that more energy is converted into ultrasound waves in the liquid,resulting in a more intense sonication.
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.
Please consider, that very intense sonication may reduce the water droplets to a size, that an almost stable emulsion is being formed that will require special means(e.g. centrifuge) to be separated.
Although sonication gives a intense mixing, it is a non-thermal processing method.
These alternating high pressure andlow pressure cycles of 20,000 times per second of sonication create intense shear forces and liquid jets.
Sonication applies intense shear forces and stress to the medium and releases thereby high extract yields in a very short extraction time.
Ultrasonic milling of harder particles requires sonication under pressure to generate intense cavitation.
Under intense forces, such as sonication or detonation, graphite can be transformed into diamond.
Hielscher's VialTweeter and CupHorn are accessories for indirect sonication thatdeliver highly focussed ultrasonic energy for an intense indirect sonication.
Sonication in pulse mode means the ultrasonicator generates high intense ultrasonic waves in periodical cycles.
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.
The ultrasonic device UP200St is a very versatile basic unit that can be turned from a common probe-type device(used for powerful direct sonication) with accessories such as the VialTweeter or TD_CupHorn into a reliable tool for intense indirect sonication.
Hence, the enzymes should be added to the biomass slurry after the sonication as intense ultrasound inactivates enzymes, which is a not desired effect.
