GeneVac miVac QUATTRO Series Vacuum Centrifugal Concentrator

Overview

The GeneVac miVac QUATTRO Series is a modular, high-performance vacuum centrifugal concentrator engineered for reproducible, solvent-agnostic sample concentration across life science, analytical chemistry, and forensic laboratories. It operates on the fundamental principle of simultaneous vacuum reduction and centrifugal force application: lowering system pressure reduces solvent vapor pressure—enabling evaporation at significantly lower temperatures—while controlled rotation prevents sample splashing, foaming, or cross-contamination. Unlike simple rotary evaporators or nitrogen blow-down systems, the QUATTRO integrates precise temperature regulation (ambient to 80 °C), dynamic vacuum control (down to 2 mbar), and high-stability rotor dynamics (1130 rpm) within a single compact platform. Its design prioritizes thermal integrity and solvent recovery efficiency—critical when processing thermolabile biomolecules (e.g., nucleic acids, peptides, metabolites) or volatile organic compounds (VOCs) requiring strict volatility management.

Key Features

• Modular architecture enables flexible configuration for evolving lab workflows—rotor trays, cold trap assemblies, and interface modules are field-swappable without recalibration.
• Integrated −50 °C cold trap with selectable operational modes (manual defrost, auto-defrost, continuous condensation) ensures consistent solvent capture across multi-hour runs—eliminating manual intervention and downtime associated with ice buildup.
• Three programmable evaporation profiles (Water, Alcohol, Other Solvents) automatically optimize ramp rates, final vacuum setpoints, and hold times based on solvent volatility and heat sensitivity—reducing method development time.
• Precision temperature control (±0.5 °C stability over full range) combined with real-time vacuum monitoring supports GLP-compliant documentation of critical process parameters.
• Robust rotor compatibility: accommodates standard formats including 200-position 1.5 mL microcentrifuge tubes, 72 × 15 mL conical tubes, 36 × 50 mL tubes, and ANSI/SLAS-standard 96-well plates—enabling parallel processing without adapter dependency.
• Optional digital pressure controller enables closed-loop vacuum regulation, essential for reproducible concentration of low-boiling solvents (e.g., dichloromethane, ethyl acetate) where pressure drift directly impacts evaporation kinetics.

Sample Compatibility & Compliance

The miVac QUATTRO handles aqueous, polar aprotic, and moderately volatile organic solvents—including methanol, acetonitrile, ethanol, acetone, and buffer-based extractions—without compromising sample integrity. It is routinely deployed in workflows aligned with ISO/IEC 17025-accredited testing laboratories and supports audit-ready operation under FDA 21 CFR Part 11 when paired with validated software configurations. The system meets CE marking requirements for electromagnetic compatibility (EMC Directive 2014/30/EU) and low-voltage safety (LVD Directive 2014/35/EU). All wetted surfaces contact only chemically inert stainless steel, PTFE, or borosilicate glass—ensuring compatibility with aggressive solvents and eliminating leachables in sensitive applications such as LC-MS sample prep or forensic toxicology.

Software & Data Management

The QUATTRO operates via an intuitive touchscreen interface with embedded method storage (≥100 protocols), time-stamped run logs, and exportable CSV data files containing vacuum history, temperature profile, rotational speed, and runtime. When integrated with GeneVac’s optional PC-based ControlSuite™ software, users gain access to remote monitoring, electronic signature-enabled method locking, and automated report generation compliant with ALCOA+ data integrity principles. Audit trails record all parameter changes, user logins, and system events—fully traceable for GMP/GLP audits. Data exports integrate natively with LIMS platforms via standard FTP or network share protocols.

Applications

• Molecular biology: DNA/RNA precipitation recovery post-phenol-chloroform extraction; enzymatic reaction cleanup prior to sequencing library prep.
• Pharmaceutical QC: Residual solvent removal from API intermediates per ICH Q3C guidelines; concentrate stability-indicating assay samples for HPLC analysis.
• Environmental testing: Pre-concentration of water extracts (e.g., EPA Method 525.3) prior to GC-MS detection of pesticides and PAHs.
• Forensic toxicology: Evaporation of urine or blood extracts after solid-phase extraction—preserving unstable analytes such as benzodiazepines or synthetic cannabinoids.
• Food & agricultural labs: Reduction of complex matrix extracts (e.g., QuEChERS) prior to multi-residue pesticide screening by LC-MS/MS.
• Academic research: High-throughput concentration of metabolomics samples across 96-well plates, minimizing inter-well variability and enabling statistical power in untargeted profiling.

FAQ

What solvent types are compatible with the miVac QUATTRO?
The system is validated for water, alcohols (methanol, ethanol, isopropanol), acetone, acetonitrile, ethyl acetate, and dichloromethane. Chlorinated and highly fluorinated solvents require optional corrosion-resistant cold trap liners and consultation with GeneVac technical support.
Can the QUATTRO be used under inert gas conditions?
Yes—when equipped with the optional inert gas purge kit, the chamber can be purged with nitrogen or argon prior to and during concentration, protecting oxygen-sensitive compounds such as reduced glutathione or certain metalloproteins.
Is method transfer between miVac models supported?
Method parameters (temperature ramps, vacuum targets, spin profiles) are fully portable across the miVac platform (DNA, Duo, QUATTRO) via USB export/import; however, maximum capacity and rotor geometry must be verified for physical compatibility.
Does the system comply with FDA 21 CFR Part 11 requirements?
Out-of-the-box compliance requires installation of ControlSuite™ software with configured electronic signatures, audit trail logging, and role-based access control—validated per laboratory-specific SOPs and risk assessment.
What maintenance is required for long-term reliability?
Scheduled maintenance includes quarterly cold trap inspection, annual vacuum pump oil replacement (if oil-sealed pump is installed), and biannual calibration verification of temperature and pressure sensors using NIST-traceable references.
