Non-contact DNA Ultrasonic Fragmenter

The principle of non-contact ultrasonic DNA fragmentation devices is based on the mechanical vibrations and cavitation effects generated by ultrasonic waves. High-frequency electrical signals produced by the ultrasonic generator are converted into mechanical vibrations via a transducer, which are then applied to the liquid containing the DNA sample.

Under ultrasonic influence, microscopic bubbles form within the liquid medium. These bubbles rapidly expand and implode, generating intense shock waves and microjets capable of penetrating cell membranes and nucleic acid molecules. This process precisely breaks DNA molecular chains, making the device suitable for bacterial cell disruption, protein extraction, DNA fragmentation for next-generation sequencing samples, immunoprecipitation experiments, fungal spore disruption, emulsification, homogenization, accelerated dissolution, and catalytic reactions. It plays a particularly crucial role in DNA sample processing for molecular biology research.

The device features a 7-inch touchscreen interface, allowing customizable settings for ultrasonic duration, interval time, power output, and alarm temperature thresholds. It includes real-time sample temperature monitoring, 20-100kHz mixed-frequency ultrasonic capability with adaptive frequency tuning, and automatic fault alarm functionality.

Applications span the following fields:
1. Genomics: NGS library preparation (WGS, WES), metagenomics research.
2. Next-Generation Sequencing (NGS): DNA fragmentation during library preparation.
3. Epigenetics research: Sample processing for ChIP-seq, ATAC-seq, and similar experiments.
4. Molecular diagnostics: Fragmentation of DNA extracted from FFPE samples.
5. Synthetic biology: Preparation of DNA fragments prior to genome assembly.
6. Forensic testing: Standardized processing of trace DNA samples.
