LabTech Flex-HPSE Automated High-Pressure Solvent Extractor

Overview

The LabTech Flex-HPSE Automated High-Pressure Solvent Extractor is an engineered solution for accelerated solvent extraction (ASE®-compatible) of organic analytes from solid and semi-solid matrices. It operates on the principle of pressurized liquid extraction (PLE), where elevated temperature and pressure maintain solvents in the liquid phase above their normal boiling points—enhancing solvation power, diffusion kinetics, and mass transfer efficiency. By combining thermodynamic optimization with precise fluidic control, the Flex-HPSE achieves complete matrix penetration and quantitative recovery of target compounds—including PAHs, PCBs, pesticides, pharmaceutical residues, plasticizers, and lipid-soluble contaminants—while minimizing thermal degradation and co-extraction of interfering macromolecules. Its dual-channel architecture enables parallel processing without cross-contamination, delivering reproducible extractions compliant with regulatory method requirements across environmental monitoring, food safety testing, polymer quality assurance, and pharmaceutical raw material analysis.

Key Features

• Dual-channel XYZ robotic platform with independent motion control ensures synchronized yet isolated operation of two extraction cells—eliminating carryover and enabling true high-throughput workflow scalability.
• Advanced cell-sealing mechanism utilizing multi-stage metal-to-metal compression gaskets and real-time pressure integrity verification prevents solvent leakage under maximum operating conditions (up to 20.6 MPa).
• Modular cell configuration supports interchangeable extraction vessels (15 mL, 22 mL, 34 mL, and 45 mL) with standardized threading and thermal coupling—enabling method flexibility without hardware reconfiguration.
• Integrated solvent delivery system with pulse-free high-pressure pump, inert gas purge capability, and pre-heated solvent lines minimizes dwell time and ensures consistent thermal equilibration prior to cell pressurization.
• Full enclosure with interlocked access doors, emergency stop rotary switch, and internal vapor containment chamber allow safe operation outside fume hoods while meeting IEC 61010-1 electrical safety standards.
• Method-driven software interface permits granular definition of extraction segments—pre-rinse, static extraction, flush, and purge—with adjustable hold times, ramp rates, and solvent composition switching (up to 4 solvent channels).

Sample Compatibility & Compliance

The Flex-HPSE accommodates a broad range of sample types including soil, sediment, sludge, plant tissue, animal feed, edible oils, polymer pellets, and composite materials. Sample loading is performed manually into reusable stainless-steel or inert quartz extraction cells; no consumable cartridges are required. All wetted components are constructed from 316L stainless steel, Hastelloy C-276, or PEEK—ensuring chemical resistance to chlorinated solvents (e.g., dichloromethane), polar organics (e.g., methanol, acetone), and acidic/basic modifiers. The system meets design and performance criteria outlined in EPA Method 3545A (Pressurized Fluid Extraction), ISO 13877 (Soil Quality – Determination of Hydrocarbons), ASTM D7699 (Standard Guide for PLE), and USP (Residual Solvents). Data integrity features—including electronic signatures, audit trails, and role-based user permissions—support GLP and GMP compliance under FDA 21 CFR Part 11.

Software & Data Management

The Flex-HPSE is controlled via a dedicated Windows-based application with touchscreen-optimized UI and optional remote desktop access. Extraction methods are stored as encrypted XML files with version history and change logs. Each run generates a timestamped report containing instrument parameters (temperature setpoint, actual cell temperature, pressure profile, solvent volume, cycle duration), operator ID, and calibration status flags. Raw data export supports CSV, PDF, and LIMS-compatible formats. System diagnostics include predictive maintenance alerts based on pump stroke count, seal wear estimation, and thermal module drift compensation—facilitating scheduled service intervals aligned with ISO/IEC 17025 quality management frameworks.

Applications

• Environmental laboratories performing routine analysis of persistent organic pollutants (POPs) in contaminated soils and dredged sediments.
• Food testing facilities quantifying pesticide residues in fruits, vegetables, cereals, and infant formula according to EU MRL regulations.
• Pharmaceutical QC labs extracting residual solvents from active pharmaceutical ingredients (APIs) and excipients per ICH Q3C guidelines.
• Materials science research groups isolating additives (e.g., antioxidants, UV stabilizers) from polyolefins and elastomers for GC-MS characterization.
• Academic and government research centers developing novel extraction protocols for microplastics, PFAS, or emerging contaminants in complex biological matrices.

FAQ

What solvent types are compatible with the Flex-HPSE?
The system supports common organic solvents including hexane, acetone, dichloromethane, ethyl acetate, methanol, and acetonitrile—as well as binary and ternary mixtures. Corrosive solvents (e.g., concentrated acids/bases) require validation of wetted material compatibility.
Can extraction cells be cleaned and reused?
Yes—stainless-steel and quartz cells are fully autoclavable and resistant to ultrasonic cleaning. Seal gaskets are replaceable and rated for ≥200 cycles under standard operating conditions.
Is method validation support available?
LabTech provides IQ/OQ documentation templates, reference test protocols for recovery and precision assessment, and optional third-party qualification services aligned with ISO/IEC 17025 requirements.
How is system performance verified over time?
Built-in calibration routines verify temperature sensor accuracy (±0.5 °C), pressure transducer linearity (±0.25% FS), and solvent delivery volumetric precision (±1.5% RSD) at user-defined intervals.
Does the Flex-HPSE integrate with laboratory information management systems (LIMS)?
Yes—via configurable API endpoints and structured data export (CSV/XML), supporting bidirectional communication with major LIMS platforms including Thermo Fisher SampleManager, LabVantage, and STARLIMS.
