Eenzel- a Multi-Röhre VialTweeter – Sonikatioun vun zouenen Fläschen

Sonication is a critical technique in modern laboratories for sample preparation, ranging from cell lysis and DNA fragmentation to nanoparticle dispersion. The Hielscher VialTweeter® models offers a specialized solution for the sterile and contamination-free sonication of closed vials. By utilizing the principle of indirect sonication, this technology ensures that samples are treated with high-intensity ultrasonic energy without ever being opened or coming into contact with a probe.

Who Benefits from Using a VialTweeter Sonicator?

The VialTweeter is particularly valuable for laboratories that need intensive, reproducible sonication while keeping samples sealed. It benefits researchers working with contamination-sensitive, hazardous, volatile or limited-volume materials, as well as teams processing multiple samples under identical conditions.

Typical users include:

• Molecular biology and genomics laboratories performing cell lysis, protein extraction, DNA or RNA shearing and sample preparation for PCR, sequencing, Western blotting or mass spectrometry.
• Microbiology and biosafety laboratories processing bacteria, yeast, viruses or potentially infectious specimens while minimizing aerosol formation and operator exposure.
• Clinical and diagnostic laboratories that require clean, traceable and reproducible preparation of patient-derived or otherwise precious samples.
• Pharmaceutical and biotechnology researchers developing vaccines, proteins, enzymes, liposomes, emulsions and other biological formulations.
• Nanotechnology and materials-science laboratories dispersing nanoparticles, carbon nanotubes, graphene, metal oxides or polymer particles without opening the vessel.
• Environmental and analytical laboratories preparing soil, plant or fluid samples for trace-element, pollutant or compositional analysis.

VialTweeter Modeller: Single-Tube a Multi-Tube Sonicator

D'VialTweeter Net-Kontakt Sonicatoren sinn an zwou Varianten verfügbar – als Single-Tube a Multi-Tube Sonicator
Déi geschlossene Vial Ultrasonicator Modeller sinn entwéckelt fir eng breet Palette vu Laborveraarbechtungsbedürfnisser z'empfänken, vu High-Throughput Workflows bis spezialiséiert Single-Probe Virbereedung.
De Standard Multi-Tube VialTweeter (S26d11x10) ass konstruéiert fir déi simultan Sonikatioun vu bis zu 10 Standardfläschen – wéi 0,5ml bis 2,0ml Eppendorf Tube a Reagenzglieser – garantéiert konsequent, identesch Konditiounen iwwer all Echantillon. Zousätzlech, fir de Multi-Tube VialTweeter ass de VialPress Accessoire verfügbar, deen et erlaabt op engem eenzege Behälter vu bis zu 500ml fir indirekt Sonikatioun ze klemmen.
 
 
The Single-Tube VialTweeter (VT26dxx) ass de personaliséierte Modell, speziell fir d'indirekt Sonikatioun vun eenzel Fläschen entworf, wat erlaabt datt d'Sonotrode präzis ugepasst ass fir spezifesch Röhre Dimensiounen an eenzegaartege Probe Container Ufuerderunge ze passen.

Steril Sonication vun zougemaach Fläschen a Reagenzglieser

D'VialTweeter closed-vial sonication Technologie erlaabt eng steril, aseptesch Probepräparatioun andeems d'Ultraschallenergie duerch d'Mauer vun engem versiegelt Röhre iwwerdroen. D'Probe bleift isoléiert vun der Sonotrode an der Ëmgéigend während der Veraarbechtung. D'Hielscher VialTweeter Systemer applizéieren dëse Prinzip an zwee komplementär Formater: eng Multi-Tube Konfiguratioun fir d'simultan Behandlung vu bis zu zéng Fläschen a Fläschspezifesch VialTweeter-Spec Konfiguratiounen fir intensiv Sonikatioun vun engem eenzegen Röhre.
In this context, sterile sonication means that an aseptically prepared sample can remain inside its closed, sterile vial during ultrasonic treatment. Because no probe enters the liquid, there is no direct contact between the ultrasonic tool and the sample. The closed format also limits aerosol formation, evaporation and exposure of operators to biological or particulate materials.

Closed-vial sonication helps to preserve the sterility and containment of a properly prepared and securely sealed sample. Closure integrity, tube compatibility and the complete workflow must still be validated for regulated, cleanroom or high-containment applications.
