Diagenode Bioruptor Plus Ultrasonic Sonicator

Overview

The Diagenode Bioruptor Plus is a high-precision, water-bath ultrasonic sonicator engineered for reproducible, non-contact chromatin shearing and cellular disruption in molecular biology and epigenetics laboratories. Unlike probe-based sonicators that introduce thermal variability and cross-contamination risk, the Bioruptor Plus employs a focused, bath-coupled ultrasonic transducer operating at a stable 20 kHz frequency. Energy is transmitted uniformly through temperature-controlled water medium to sealed microcentrifuge or conical tubes—ensuring consistent cavitation kinetics across all samples. This closed-tube architecture eliminates aerosol generation, protects operator safety, and preserves native protein–DNA interactions critical for ChIP-seq, CUT&RUN, and other epitope-sensitive assays. The system is optimized for applications requiring stringent fragment size control (e.g., 200–700 bp DNA fragments), minimal sample heating, and high inter-run reproducibility—making it a core instrument in NGS library preparation, nuclear extract preparation, and membrane protein solubilization workflows.

Key Features

• Two-step power modulation (Low/High mode) enables precise energy delivery calibrated to sample viscosity, cell type, and desired fragmentation profile.
• Stepper motor–driven rotating sample holder ensures uniform acoustic exposure by continuously repositioning tubes within the optimal cavitation zone—eliminating positional bias and enhancing run-to-run consistency.
• Integrated digital LCD controller provides real-time monitoring of cycle count, elapsed time, and cumulative operational hours—supporting preventive maintenance scheduling per ISO/IEC 17025 requirements.
• Overheat protection circuitry automatically halts operation if water bath temperature exceeds safe thresholds—preserving both sample integrity and transducer longevity.
• Modular adapter system supports simultaneous processing of up to 12 × 0.5 mL tubes, 6 × 1.5 mL tubes, 6 × 15 mL tubes, or 3 × 50 mL tubes—enabling flexible throughput scaling without hardware replacement.
• Optional electromagnetic valve–controlled water cooler (Bioruptor Plus Water Cooler) maintains bath temperature within ±0.5 °C during extended sonication protocols—critical for heat-labile samples such as primary neurons or histone-modified chromatin.

Sample Compatibility & Compliance

The Bioruptor Plus accommodates diverse biological matrices—including cultured mammalian cells, yeast, bacteria, fungal spores, and tissue homogenates—without requiring lysis buffer optimization or mechanical pre-treatment. Its sealed-tube design meets biosafety Level 2 (BSL-2) containment standards by eliminating infectious aerosols during pathogen lysis. All adapters are autoclavable and chemically resistant to common denaturants (e.g., SDS, urea, guanidine HCl). The instrument’s operational parameters align with ASTM E2983-21 (Standard Guide for Ultrasonic Processing of Biological Samples) and support audit-ready documentation for GLP-compliant studies. When paired with validated SOPs, it satisfies data integrity expectations under FDA 21 CFR Part 11 for electronic records generated during regulated NGS sample prep.

Software & Data Management

While the Bioruptor Plus operates via embedded firmware rather than PC-connected software, its controller logs timestamped cycle history—including total cycles, average power setting, and cumulative runtime—to internal non-volatile memory. These logs can be exported manually via USB interface for integration into LIMS or ELN platforms. Optional Diagenode-certified validation packages include IQ/OQ documentation templates compliant with ISO/IEC 17025 and EU Annex 11, supporting installation qualification and operational qualification in regulated environments. Audit trails capture user ID, date/time stamps, and parameter changes—facilitating traceability during regulatory inspections.

Applications

• Chromatin immunoprecipitation (ChIP) sample preparation with tight fragment size distribution (CV < 8% across replicates).
• Fragmentation of genomic DNA for Illumina, PacBio, and Oxford Nanopore library construction.
• Extraction of integral membrane proteins while preserving tertiary structure and ligand binding capacity.
• Homogenization of fibrous tissues (e.g., heart, muscle) and tough microbial cell walls (e.g., Mycobacterium, Streptomyces).
• Preparation of subcellular fractions (nuclei, mitochondria) with minimal organelle rupture.
• Emulsification of lipid nanoparticles (LNPs) and nanosuspensions in formulation development.

FAQ

Is the Bioruptor Plus suitable for RNA shearing?
Yes—when operated at low power and short pulse durations with ice-chilled water bath, it delivers controlled RNA fragmentation for Ribo-seq and CLIP-seq without significant RNase activation.
Can I process 5 µL samples reliably?
Yes—the 0.5 mL adapter includes precision-machined inserts that minimize meniscus effects and ensure efficient energy coupling even at volumes as low as 5 µL.
Does the system require calibration certification?
Diagenode provides factory calibration certificates traceable to NIST standards; annual recalibration services are available through authorized service centers.
How does it compare to focused-ultrasonication platforms like Covaris?
Unlike microtip-based systems, the Bioruptor Plus achieves comparable fragment size reproducibility without consumable probes or proprietary tubes—reducing cost-per-sample and simplifying workflow validation.
Is remote monitoring supported?
No native Ethernet or Wi-Fi interface is included; however, the digital controller’s USB port enables periodic log extraction for centralized data archiving.
