The Story
Dry Contactless Ultrasonicator – QualiUltra™ DCL Series
The QualiUltra™ DCL Series Dry Contactless Ultrasonicator is a non-contact, sealed-tube processing system designed for handling trace and low-volume samples. Its probe-free architecture eliminates direct interaction between the sonication source and the sample, helping lower contamination risks while streamlining workflow setup compared to conventional probe-based systems.
This system uses a bottom-mounted ultrasonic module that delivers energy through sealed sample tubes, enabling efficient processing without opening or transferring contents. Integrated semiconductor-based cooling maintains a controlled low-temperature environment throughout operation, helping preserve the stability of temperature-sensitive biomolecules such as proteins and nucleic acids.
The QualiUltra™ DCL Series is optimized for rapid pretreatment in high-throughput molecular workflows, including nucleic acid preparation steps used in detection and analysis pipelines. Once processing is complete, samples can proceed directly into amplification, hybridization, or other downstream procedures with minimal handling, supporting smoother laboratory workflows.
Designed for compact bench-top use, this Ultrasonicator supports small-volume applications such as membrane disruption and cell lysis in sealed 2.0 mL tubes. It operates within a working volume range of 500–1000 µL, making it suitable for a wide variety of trace-sample protocols that require speed and consistency.
Temperature control is managed through an integrated semiconductor refrigeration system, maintaining a stable operating range of approximately 8–12°C during processing. This helps reduce heat-related degradation of sensitive biological targets. The system also supports stored parameter settings, allowing users to repeat optimized conditions for consistent experimental outcomes across multiple runs.

Theory and Method – QualiUltra™ DCL Series Dry Contactless Ultrasonicator
The QualiUltra™ DCL Series operates using indirect ultrasonic energy transmission from a bottom-mounted ultrasound module into sealed sample tubes. This approach generates controlled mechanical forces through ultrasonic waves, enabling efficient cell disruption and membrane breakage without the need for probe immersion. By eliminating direct probe-to-sample contact, the system helps reduce contamination risk and simplifies routine laboratory handling.
A typical workflow begins by loading 500–1000 µL of sample into a compatible 2.0 mL sealed ultrasound tube. The tube is then placed into the instrument chamber, where operational parameters such as ultrasonic power level and total processing time are selected, with timing adjustable within a 1–900 second range depending on sample requirements.
During operation, an integrated semiconductor-based cooling system maintains a stable low-temperature environment, helping to protect temperature-sensitive biomolecules throughout the sonication process. After completion, the processed sample can be directly transferred to downstream applications such as nucleic acid amplification, hybridization assays, purification steps, or other analytical workflows without additional handling steps.
