Eşzamanlı Numune Hazırlama İçin VialTweeter ile UP200St

In laboratories, it is often necessary to prepare multiple samples simultaneously at the same process conditions. The VialTweeter enables for the simultaneous sonication of up to 10 vials at the same intensity. Thereby, the VialTweeter is a reliable lab homogenizer for homogenization, emulsification, dispersing and deagglomeration, extraction, lysis, dissolve, as well as the degassing of fluids. Due to the principle of indirect sonication, no probe is immersed into the sample so that cross-contamination and sample loss is completely avoided.

In the lab, often multiple samples of small volumes have to be prepared simultaneously – in order to mix, homogenize, emulsify, disperse, disintegrate or degas a liquid medium. The VialTweeter provides high power ultrasound to fulfill the required application by introducing ultrasonic cavitation indirectly through the vessel’s wall into up to 10 samples at the same time. Thereby, cross-contamination and sample loss are completely avoided.
In combination with the digital ultrasonic processor UP200St, the VialTweeter allows for the effective and comfortable sonication of up to 10 vials simultaneously and without cross-contamination. As the same ultrasound intensity is delivered to each sample, the sonication results are even and reproducible.

While ultrasonic cleaning baths and tanks provide only low ultrasound energy resulting in incomplete sample preparation results, the VialTweeter transmits intense ultrasonic forces through the vessels into the sample. During the indirect sonication, the test tubes remain permanently closed so that the sample cannot be contaminated, spoiled or volatilize. Sample losses are avoided, too.
Many standard test vials, such as auto-sampler vials, micro-centrifuge vials, reagent vials such as Eppendorf tubes or Nunc tubes of 1 to 5 mL fit into the VialTweeter. To provide even more flexibility, the adjustable and removable VialPress allows to press larger sample vessels to the front surface of the VialTweeter block sonotrode. Thereby, up to 5 larger vials can be sonicated indirectly at the same time.
Advantages of the VialTweeter at a glance

  • Intense sonication of up to 10 vials simultaneously
  • Indirect sonication at high ultrasonic intensity through vessel wall into the sample
  • Indirect sonication avoids cross-contamination and sample loss
  • Reproducible results due to adjustable and controllable sonication amplitude
  • The VialPress enables you to sonicate larger tubes
  • Adjustable pulse mode from 0 to 100%
  • Autoclavable

The VialTweeter Setup consists in three major components, which are easy to mount and provide high user-friendliness and work comfort: The ultrasonic processor UP200St-G, the transducer UP200St-T and the VialTweeter.
The 200 watts ultrasonic processor is the ultrasonic driver of the VialTweeter. Due to its 200 watts of ultrasound power, it becomes possible to sonicate up to 10 vials at an ultrasonic intensity of up to 10 watts per each test tube. This makes the VialTweeter a very powerful and reliable work unit.

About the UP200St Core Unit

The UP200St offers so many applications due to the manifold available accessories. The core unit UP200St can be used as conventional probe ultrasonicator, too. Just dismount the VialTweeter block sonotrode and use one of the various sonotrodes, which are available for the UP200St.
This allows the user to change easy and quickly between indirect and direct sonication of very small up to mid-size samples. With its 200 watts ultrasound power, the UP200St handles effortlessly volumes from 0.1mL to 1000mL.

n this video, we showcase a specialized version of the Hielscher VialTweeter (https://www.hielscher.com/VT) designed for sonication of closed sample vials. The standard Hielscher VialTweeter is an essential tool in biotech research and sample preparation for analyzing a diverse range of laboratory samples. This device enables intensive, consistent, and reproducible sonication of up to 10 closed sample vessels simultaneously. This capability facilitates high-throughput processes such as cell disruption, DNA fragmentation, emulsification, dispersion, and degassing, all achieved with short sonication times. For sample vessels that don't fit the standard VialTweeter, Hielscher Ultrasonics offers custom larger or smaller versions, accommodating one to ten specialized sample vessels.
