Overview
The GeneVac miVac DUO Series is a compact, modular vacuum centrifugal concentrator engineered for precise, reproducible solvent removal from biological, chemical, and analytical samples under controlled thermal and vacuum conditions. It operates on the fundamental principle of vacuum-assisted evaporation: by reducing ambient pressure within the chamber, the boiling point of solvents—such as water, ethanol, acetone, acetonitrile, and ethyl acetate—is significantly lowered, enabling efficient concentration at temperatures well below their atmospheric boiling points. Combined with high-speed centrifugation (1465 rpm), the system maintains sample integrity by counteracting aerosol formation and preventing tube ejection or cross-contamination—a critical requirement for sensitive nucleic acid, protein, metabolite, and small-molecule workflows. Designed and manufactured in the UK, the miVac DUO integrates a −50 °C cold trap with selectable defrost modes (manual, auto, or continuous condensation), eliminating the need for routine manual frost removal and supporting unattended overnight operation.
Key Features
- Modular architecture allows flexible configuration for diverse lab environments—from individual benchtop use to integration into automated sample preparation workflows.
- Intelligent solvent-specific operating profiles (Water, Alcohol, Other) automatically optimize vacuum ramping, temperature setpoint, and rotational timing to maximize recovery and minimize degradation.
- Integrated −50 °C cold trap with dual-mode condensation ensures high-efficiency solvent capture across volatile organic solvents and aqueous matrices, reducing maintenance frequency and improving long-term system stability.
- Precision temperature control (30–80 °C in 1 °C increments) coupled with real-time vacuum monitoring enables method reproducibility compliant with GLP and GMP documentation requirements.
- Multiple rotor options support broad compatibility: 48-position 1.5 mL microcentrifuge tubes, 12-position 15 mL conical tubes, 8-position 50 mL tubes, and standard 96-well plates—facilitating parallel processing without adapter changes.
- Optional electronic pressure controller provides fine-grained vacuum regulation for method-sensitive applications, such as thermolabile compound concentration or low-boiling-point solvent removal.
Sample Compatibility & Compliance
The miVac DUO accommodates a wide range of sample containers—including polypropylene and glass tubes, PCR strips, deep-well plates, and custom vials—without requiring proprietary consumables. Its design meets essential safety and performance benchmarks for regulated laboratories: mechanical construction complies with IEC 61010-1 for laboratory equipment; vacuum system integrity supports ISO 5840-1 leak-rate tolerances; and thermal calibration traceability aligns with ISO/IEC 17025 requirements when performed using accredited service providers. While not inherently 21 CFR Part 11–compliant, the system supports audit-trail-capable software interfaces (via optional GeneVac Control Suite) that enable electronic record retention, user access controls, and change management—key prerequisites for FDA-regulated QC/QA labs conducting environmental testing, forensic toxicology, pharmaceutical impurity analysis, or agricultural residue screening.
Software & Data Management
The miVac DUO operates via an intuitive front-panel interface with programmable run protocols, but achieves full data governance when paired with GeneVac’s optional PC-based Control Suite. This software enables creation, validation, and versioning of SOP-driven methods—including temperature ramps, vacuum decay profiles, and rotor-specific spin parameters. All session logs (start/stop time, final vacuum level, peak temperature, total runtime) are timestamped and exportable in CSV or PDF formats. For laboratories subject to regulatory oversight, the software supports role-based user authentication, electronic signatures, and immutable audit trails—facilitating compliance with ALCOA+ data integrity principles and internal QA audits.
Applications
- Molecular biology: DNA/RNA precipitation, oligonucleotide desalting, cDNA library concentration prior to sequencing.
- Clinical & forensic toxicology: Evaporation of urine, blood, or tissue extracts following liquid–liquid extraction or solid-phase cleanup.
- Environmental analysis: Pre-concentration of water, soil leachate, or air sampling media extracts prior to GC-MS or LC-MS/MS detection.
- Pharmaceutical development: Removal of residual solvents from synthetic intermediates, formulation excipients, or stability study samples.
- Food & agricultural testing: Concentration of pesticide residues, mycotoxins, or veterinary drug metabolites from complex food matrices.
- Academic research: Routine sample clean-up in natural product isolation, metabolomics, and proteomics pipelines where batch consistency and low carryover are essential.
FAQ
What is the maximum recommended sample volume per tube in the 50 mL rotor configuration?
The 8-position 50 mL rotor supports up to 50 mL per tube, though optimal evaporation efficiency is achieved at ≤40 mL fill volume to ensure adequate headspace and prevent bumping under vacuum.
Can the miVac DUO be used for lyophilization?
No—the miVac DUO is designed for vacuum centrifugal concentration only and does not provide shelf freezing or primary drying capability required for true lyophilization.
Is remote monitoring supported?
Yes, when connected to GeneVac Control Suite via Ethernet or USB, real-time status (vacuum level, temperature, rpm, elapsed time) can be viewed and controlled remotely through a secure local network.
How often does the cold trap require maintenance?
With continuous condensation mode enabled and typical usage (≤8 hrs/day), the cold trap requires no manual defrosting for ≥7 days; service intervals depend on solvent load and composition, with annual professional calibration recommended.
Does the system meet ISO 13485 requirements for medical device manufacturing environments?
While the hardware itself is not certified to ISO 13485, documented IQ/OQ protocols are available from GeneVac’s technical support team to support qualification in Class II/III device production settings where sample prep equipment must be validated.
