Contactless Ultrasonicator
Contactless Ultrasonicator – Sealed Tube Ultrasonic Processing
A Contactless Ultrasonicator processes samples within sealed tubes without direct probe contact. This configuration supports contamination-controlled workflows, minimizes carryover risk, and delivers stable, repeatable results when multiple tubes require identical ultrasonic conditions.
This sealed-tube ultrasonic approach is ideal for sensitive laboratory applications where sample integrity and cross-contamination prevention are critical. It ensures consistent energy transfer while maintaining a closed environment throughout processing.
QualiUltra™ Contactless Ultrasonication Platforms
QualiUltra™ provides multiple contact-free ultrasonic processing configurations designed for flexible laboratory requirements:
- Multi-tube rack systems for parallel batch processing of sealed samples under uniform conditions
- Indirect cup sonication systems for non-contact energy transfer through an external medium
- Dry non-contact cooling setups for temperature-sensitive trace-level workflows
- Compact sealed microtube processing units for efficient small-volume pretreatment in closed vessels
These configurations support a wide range of sealed-sample ultrasonic workflows, enabling consistent processing performance across different tube formats and laboratory applications.
Applications of Contactless Ultrasonicator
Molecular Biology and Genomics Sample Preparation
Sealed-tube ultrasonic processing supports workflows such as ChIP sample preparation, DNA fragmentation, nucleic acid extraction, and sequencing sample homogenization. Multi-position tube racks help maintain consistent processing conditions across multiple samples in a single run, improving workflow uniformity and reproducibility.
Microbiology Disruption and Intracellular Extraction
Contactless sonication enables efficient disruption of bacterial and cellular structures while supporting downstream extraction of intracellular proteins and nucleic acids. This closed-tube approach helps maintain a cleaner workflow by limiting exposure and reducing handling-related variability.
Biopharmaceutical and Formulation Processes
Sealed ultrasonic processing is suitable for handling sensitive reagents and supporting emulsification-related reactions. Systems such as the FC Series are used for small-volume liposome preparation and controlled emulsification steps where precise cycle management is important for consistent outcomes.
Heat-Sensitive Samples and Enhanced Safety Handling
Integrated temperature control with real-time monitoring helps protect temperature-sensitive biomolecules such as proteins and nucleic acids during processing. The non-contact design also helps limit aerosol or mist formation during high-energy sonication, supporting safer laboratory operation and improved containment during disruptive workflows.
