Hannuo HN98-IIIB Non-Contact Ultrasonic Cell Disruptor

Overview

The Hannuo HN98-IIIB Non-Contact Ultrasonic Cell Disruptor is an engineered platform for high-throughput, contamination-free nucleic acid shearing and cellular lysis. Unlike conventional probe-based sonicators, this system employs focused ultrasonic energy transmitted through the walls of sealed microcentrifuge tubes—eliminating direct probe contact with samples and thereby ensuring strict biosafety compliance in BSL-2 and higher containment environments. Its core operating principle relies on resonant acoustic cavitation induced by high-intensity ultrasonic waves (19–30 kHz) within liquid media, generating controlled hydrodynamic shear forces that fragment chromatin, lyse bacterial and mammalian cells, and shear genomic DNA or RNA without thermal denaturation or metal ion contamination. Designed for reproducible, scalable sample preparation, the HN98-IIIB supports both manual and protocol-driven operation across diverse life science workflows—including next-generation sequencing (NGS), ChIP-seq, epigenetic profiling, and viral vector production.

Key Features

• Non-contact transduction: Ultrasound energy is coupled into samples via titanium horn and water bath medium—no probe insertion, no cross-contamination, no aerosol generation.
• High parallelism: Simultaneous processing of up to 32 individual samples (0.1–2 mL each) in standardized 1.5/2.0 mL microtubes, enabling full plate-level throughput.
• Precision parameter control: Adjustable duty cycle (1–99.9%), amplitude modulation, and programmable time cycles ensure method consistency across replicates and users.
• Integrated thermal management: Equipped with a dedicated cooling interface compatible with external recirculating chillers; maintains sample temperature between −5 °C and 100 °C during extended sonication.
• Intuitive touchscreen interface: Graphical UI supports multi-step protocol storage, real-time power monitoring, and audit-ready operation logs.
• Modular communication architecture: Optional RS232/RS485 ports enable integration into LIMS or automated lab platforms compliant with ASTM E1578 and ISO/IEC 17025 data traceability requirements.

Sample Compatibility & Compliance

The HN98-IIIB accommodates standard polypropylene or PCR-grade microcentrifuge tubes (1.5 mL and 2.0 mL), including low-binding and skirted formats. It is validated for use with sensitive biological matrices—e.g., primary human PBMCs, cultured adherent cell lines, bacterial cultures (E. coli, Bacillus spp.), tissue homogenates, and viral lysates (adenovirus, AAV). The fully enclosed design meets CDC/NIH biosafety guidelines for handling pathogenic agents and satisfies containment criteria for GLP-compliant laboratories. All operational parameters are configurable to align with USP Analytical Instrument Qualification standards and support 21 CFR Part 11-compliant electronic records when paired with validated software extensions.

Software & Data Management

The embedded firmware supports user-defined protocol libraries with up to 99 stored methods, each containing independent settings for power level, duration, pulse interval, and temperature setpoint. Timestamped operation logs—including actual delivered power, measured bath temperature, and cycle completion status—are exportable via USB or serial interface. When integrated with Hannuo’s optional LabControl Suite (v3.2+), the system enables remote scheduling, instrument health diagnostics, and automated PDF report generation compliant with ISO 15197 and CLIA quality assurance frameworks.

Applications

• Genomic DNA fragmentation for Illumina, PacBio, and Oxford Nanopore library prep
• Chromatin shearing in ChIP-qPCR and ChIP-seq workflows
• Preparation of high-titer recombinant adenoviral vectors and AAV capsid lysates
• Isolation of membrane proteins under native conditions
• RNA shearing for ribosome profiling and small RNA library construction
• Soil metagenomic extraction with minimized humic acid interference
• Emulsification and nano-dispersion of lipid nanoparticles (LNPs) and liposomes
• Controlled lysis of extremophiles and Gram-positive bacteria with rigid cell walls

FAQ

What is the maximum recommended sample volume per tube?
The optimal range is 0.1–2.0 mL per tube; volumes exceeding 2 mL may reduce cavitation efficiency and increase thermal load.
Can the HN98-IIIB be used for RNA work without RNase contamination risk?
Yes—the non-contact design eliminates probe-mediated RNase carryover; combined with RNase-free tube handling, it delivers high-fidelity RNA shearing outcomes.
Is temperature control mandatory during sonication?
For heat-sensitive targets (e.g., histone modifications, labile enzymes), active cooling is strongly recommended; the system supports integration with certified laboratory chillers (e.g., Huber, Julabo) via its standardized water-jacket interface.
How does the HN98-IIIB compare to probe sonicators in terms of reproducibility?
Inter-sample CVs for fragment size distribution are typically ≤8% (vs. ≥20% for manual probe systems), due to uniform energy coupling and absence of operator-dependent probe positioning variability.
Does the instrument comply with electromagnetic compatibility (EMC) standards?
Yes—it conforms to IEC 61326-1:2013 for laboratory equipment and meets CE marking requirements for EMC and low-voltage directive compliance.
