Overview
The Saprete ZQ-6A Fully Automated Liquid-Liquid Extractor is an engineered solution for high-throughput, reproducible liquid-liquid extraction (LLE) in regulated and research-intensive laboratory environments. Based on the fundamental principle of differential solute partitioning between two immiscible or partially miscible phases—typically an aqueous sample matrix and an organic solvent—the ZQ-6A automates the complete LLE workflow: solvent addition, phase mixing via controlled pneumatic oscillation, phase separation by gravity settling, aqueous/organic layer separation, and post-extraction cleaning. Designed to replace manual, operator-dependent separatory funnel procedures, the system minimizes analyst exposure to hazardous solvents, eliminates inter-operator variability, and ensures strict adherence to method-defined parameters across all six parallel extraction channels.
Key Features
- Fully automated six-channel architecture with independent control per station—enabling simultaneous processing of up to six samples without cross-contamination risk.
- Pneumatic oscillation mechanism delivering consistent, adjustable amplitude and frequency—optimized for efficient mass transfer while preserving analyte integrity and minimizing emulsion formation.
- Integrated touchscreen HMI (Human-Machine Interface) with intuitive icon-driven navigation, preloaded method templates, and real-time status monitoring (e.g., cycle progress, solvent volume dispensed, agitation duration).
- Automated post-extraction rinse sequence using designated cleaning solvent—programmable for multiple rinse cycles and drain-to-waste routing to prevent carryover.
- Centralized exhaust management system with activated carbon filtration—capturing volatile organic compounds (VOCs) and acidic fumes during solvent handling and venting operations.
- Modular separatory funnel compatibility: supports standard 500 mL and 1000 mL glass or PTFE-lined funnels with secure clamping and leak-proof sealing interfaces.
Sample Compatibility & Compliance
The ZQ-6A accommodates a broad range of aqueous matrices—including wastewater, biological fluids (urine, serum), food homogenates, pharmaceutical dissolution media, and environmental soil leachates—as well as common extraction solvents such as dichloromethane, ethyl acetate, hexane, and MTBE. All fluid pathways are chemically resistant to halogenated and polar aprotic solvents. The system complies with general laboratory safety standards (OSHA 29 CFR 1910, ISO 15190:2020) and supports GLP/GMP-aligned workflows through user-access-level permissions, audit trail logging (optional firmware upgrade), and method version control. While not certified to specific pharmacopeial monographs (e.g., USP ), its operational repeatability and documentation capabilities align with method validation requirements under ICH Q2(R2) and ISO/IEC 17025:2017.
Software & Data Management
The embedded control software provides full method definition—including solvent type and volume, oscillation profile (duration, frequency, dwell time), settling time, layer separation threshold, and cleaning protocol. All executed runs generate timestamped metadata logs (operator ID, start/end time, parameter set, error flags). Data export is supported via USB 2.0 to CSV format for integration into LIMS or ELN platforms. Optional network-enabled firmware allows remote monitoring and basic diagnostics via Ethernet, though direct cloud connectivity or FDA 21 CFR Part 11-compliant electronic signatures require third-party middleware integration.
Applications
- Environmental analysis: EPA Methods 3510C, 3520C, and 508.1 for pesticide, PCB, and PAH extraction from water and sludge.
- Food safety testing: Determination of veterinary drug residues (e.g., sulfonamides, fluoroquinolones) in milk and meat extracts per AOAC 2007.01 and GB 23200 series standards.
- Pharmaceutical QC: Residual solvent removal from active pharmaceutical ingredients (APIs) and excipient blends prior to HPLC or GC analysis.
- Public health laboratories: High-volume screening of mycotoxins (aflatoxin B1, ochratoxin A) in cereal-based samples per ISO 15141 and GB 5009.22–2016.
- Industrial hygiene: Extraction of workplace air sampling media (e.g., XAD-2 resin) for aldehyde and ketone quantification.
FAQ
Does the ZQ-6A support custom solvent delivery volumes per channel?
Yes—each of the six stations accepts individually programmed solvent volumes (range: 5–100 mL) with ±0.5 mL volumetric accuracy via calibrated peristaltic pumps.
Can the system handle viscous or emulsion-prone samples?
It includes extended settling time configuration (up to 30 minutes) and optional centrifugal assist add-on (ZQ-CF module) for challenging phase separations.
Is routine maintenance required beyond cleaning?
Annual calibration verification of pump delivery accuracy and pneumatic pressure regulation is recommended; no consumable parts require replacement under normal operation.
What safety certifications does the instrument hold?
CE marking (EMC Directive 2014/30/EU and Low Voltage Directive 2014/35/EU); additional regional certifications (e.g., UL, KC) available upon request with model-specific documentation.
