Safe AT-AE06-Z Automated Liquid-Liquid Extractor with Precision Reagent Dispensing

Overview

The Safe AT-AE06-Z Automated Liquid-Liquid Extractor is an engineered solution for high-throughput, reproducible sample preparation in environmental and regulatory water quality laboratories. It implements a closed-loop, low-noise clean air oscillation principle—eliminating mechanical agitation and solvent vapor exposure—while integrating bidirectional gas-liquid mixing to enhance interfacial mass transfer during liquid-liquid extraction. Designed specifically for compliance-driven workflows, the system automates all critical steps: precision reagent dosing, controlled-phase mixing, pressure-relief venting, phase separation management, aqueous/organic layer collection, waste discharge, and post-run vessel cleaning. Its architecture supports standardized methods requiring strict adherence to volumetric accuracy, timing repeatability, and operator-independent operation—key requirements for GLP-compliant environmental testing.

Key Features

• 6-position independent extraction module enabling parallel processing of up to six samples with fully customizable parameters per channel
• High-accuracy peristaltic metering pump (0–50 mL range, ≥2% volumetric accuracy) for automated, traceable reagent addition—eliminating manual pipetting variability
• Closed-loop clean air circulation system with integrated HEPA-grade filtration and activated carbon adsorption to maintain sterile, solvent-free gas pathways and minimize cross-contamination risk
• Programmable agitation profile: adjustable oscillation intensity, cycle count (0–99), extraction duration (0–999 s), and rest intervals (0–999 s) to optimize partitioning kinetics for diverse analytes
• Multi-vessel compatibility: accommodates standard glass separatory funnels or extraction bottles (250 mL, 500 mL, 1000 mL, and 2000 mL); all fluid-contact valves and manifolds constructed from PTFE for chemical inertness
• Integrated waste management: dual-stage activated carbon filtration for both liquid effluent and exhaust gas, followed by centralized collection—reducing lab ventilation load and environmental release
• 7-inch industrial-grade color touchscreen interface with intuitive icon-based navigation, real-time status monitoring, and audit-trail-capable parameter logging
• Automated post-extraction sequence: pressurized wide-angle spray rinse, drain, and dry cycles—minimizing carryover and ensuring inter-sample integrity

Sample Compatibility & Compliance

The AT-AE06-Z is validated for use in accredited environmental testing laboratories performing analyses under multiple national standards, including GB 7494–1987 (anionic surfactants, methylene blue spectrophotometry), HJ 503–2009 (volatile phenols, 4-aminoantipyrine method), GB/T 16488–1996 and HJ 637–2018 (petroleum hydrocarbons, infrared spectrophotometry), and HJ 970–2018 (petroleum hydrocarbons, UV spectrophotometry). Its closed-system design prevents volatile organic compound (VOC) loss and operator exposure—critical for phenol and oil analysis. All reagent delivery and timing functions meet ISO/IEC 17025 documentation requirements for method validation, and the system’s parameter lockout, user access levels, and electronic log export support 21 CFR Part 11 readiness when paired with compliant LIMS integration.

Software & Data Management

The embedded control firmware records timestamped operational data—including dispensed volume, oscillation cycles, dwell times, pressure events, and cleaning sequence completion—for each run. Logs are exportable via USB in CSV format for QA review or audit submission. Optional remote operation via secure mobile application includes SMS alerting for cycle completion, error conditions (e.g., low reagent, clogged line, overpressure), and maintenance reminders. No cloud storage is used by default; all data remains on-device unless explicitly exported—ensuring alignment with institutional data sovereignty policies.

Applications

This extractor serves routine and high-volume applications in environmental monitoring labs, municipal water quality centers, and third-party testing facilities. Primary use cases include pre-concentration of trace-level analytes prior to GC-FID, HPLC-UV, or ICP-MS analysis; preparation of calibration standards with minimized matrix interference; and batch processing of wastewater influent/effluent samples for regulatory reporting. Its programmability also supports method development for emerging contaminants where partition coefficients and emulsion stability require fine-tuned agitation profiles.

FAQ

What safety certifications does the AT-AE06-Z hold?
It complies with IEC 61010-1:2010 for laboratory electrical equipment safety and meets CE marking requirements for EMC and low-voltage directives.
Can the system be integrated into a laboratory information management system (LIMS)?
Yes—via optional RS-232 or Ethernet interface with ASCII command protocol; full audit trail export supports GLP/GMP traceability requirements.
Is manual phase separation required after extraction?
Yes—static settling occurs automatically per programmed dwell time, but final layer separation and transfer are performed manually to preserve method fidelity per cited Chinese standards.
What maintenance is required for long-term reliability?
Quarterly inspection of PTFE valves and tubing, annual replacement of activated carbon filters (liquid and gas paths), and biannual calibration verification of the metering pump using gravimetric validation.
Does the instrument support unattended overnight operation?
Yes—equipped with thermal cutoff, overpressure relief, and leak detection; designed for continuous 24/7 operation in ventilated laboratory environments.
