Overview
The EX-TE Series Multifunctional Extraction Vessel is an engineered laboratory-scale extraction system designed for controlled solid–liquid extraction under atmospheric, reflux, vacuum-assisted, and thermally regulated conditions. Based on the principle of dynamic solvent percolation combined with optional ultrasonic cavitation enhancement, it supports a wide range of extraction modalities—including decoction, maceration, hot reflux, forced-circulation leaching, volatile oil distillation, and organic solvent recovery—commonly applied in phytochemical research, nutraceutical development, pharmaceutical process optimization, and food-grade active ingredient isolation. Its modular architecture enables reproducible small-batch processing (3–100 L working volume), making it suitable for method development prior to pilot- or production-scale transfer. The vessel operates within defined mechanical and thermal safety limits (vessel design pressure: 0.09 MPa; jacket design pressure: 0.3–0.4 MPa), conforming to standard ASME BPVC Section VIII Div. 1 guidelines for low-pressure vessels used in laboratory environments.
Key Features
- Integrated electric heating system with simultaneous bottom-and-wall heating, ensuring uniform thermal distribution and eliminating cold spots during prolonged extraction cycles.
- Triple-layer thermal insulation (stainless steel shell + mineral wool + polished cladding) minimizes heat loss and improves energy efficiency without compromising accessibility.
- Open-top structural design facilitates rapid loading/unloading, visual monitoring, and in-situ cleaning—critical for multi-product lab environments subject to strict changeover protocols.
- Programmable central controller with real-time digital display of extraction temperature, jacket temperature, agitation speed, and operational time; supports user-defined ramp/soak profiles.
- Low-level liquid detection circuit automatically deactivates heating elements when fluid volume falls below safe threshold—preventing dry-firing and extending heater service life.
- Modular expansion capability: up to 20 units can be synchronized via standardized communication interface (RS-485/Modbus RTU) for parallel batch experiments under identical process parameters.
- Optional integrated ultrasonic module featuring focused transducer arrays (15–60 kHz selectable), coupled with anchor-type agitator to maximize acoustic energy delivery across heterogeneous solid matrices.
Sample Compatibility & Compliance
The EX-TE series accommodates diverse sample forms—dried herbs, granulated powders, sliced botanicals, protein-rich biomass, starch suspensions, and fermented broths—without requiring pre-milling beyond standard lab sieving (≤2 mm particle size recommended). All wetted parts are constructed from ASTM A240 316L stainless steel, passivated per ASTM A967, ensuring resistance to organic solvents (ethanol, acetone, ethyl acetate), acidic extracts (pH 2–12), and alkaline media. The system meets general requirements for GLP-compliant laboratories as defined in OECD Principles of Good Laboratory Practice (ENV/MC/CHEM(98)17), and supports audit-ready documentation when paired with validated data logging software. While not certified for GMP manufacturing use, its design aligns with key elements of USP Analytical Instrument Qualification and ISO/IEC 17025:2017 clause 6.4.10 regarding equipment suitability verification.
Software & Data Management
Data acquisition is performed via embedded 16-bit analog-to-digital converters sampling at 1 Hz resolution. Raw sensor outputs—including temperature (PT100 Class A), level (capacitive probe), agitation torque (strain-gauge based), and optional pH/vacuum inputs—are timestamped and stored internally (2 GB flash memory, 30-day buffer at 1 Hz). Export formats include CSV and XML, compatible with LIMS integration (e.g., LabWare, Thermo Fisher SampleManager) and statistical analysis platforms (JMP, Minitab). Optional FDA 21 CFR Part 11-compliant software add-on provides electronic signatures, role-based access control, and immutable audit trails for critical parameters—supporting regulatory submissions where experimental traceability is required.
Applications
- Phytochemical screening: Quantitative recovery of flavonoids, alkaloids, terpenoids, and polyphenols from Salvia miltiorrhiza, Ginkgo biloba, and Camellia sinensis under optimized temperature/pH/solvent ratios.
- Nutraceutical R&D: Extraction of anthocyanins from berry pomace, curcuminoids from turmeric rhizomes, and omega-3 rich oils from microalgae biomass using ethanol–water gradients.
- Pharmaceutical intermediate purification: Isolation of insulin precursors from recombinant E. coli lysates via pH-controlled aqueous two-phase extraction.
- Food ingredient valorization: Recovery of natural colorants (e.g., betalains, chlorophyllin), flavor compounds (e.g., limonene, eugenol), and functional peptides from agricultural co-products.
- Solvent recycling validation: Closed-loop recovery of ethanol, hexane, or dichloromethane with inline refractometric concentration monitoring.
FAQ
What safety certifications does the EX-TE series hold?
The unit complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and carries CE marking for EMC Directive 2014/30/EU. Pressure components are fabricated per GB/T 150.1–2011 (Chinese equivalent of ASME BPVC Section VIII).
Can the system operate under vacuum?
Yes—vacuum-assisted extraction is supported down to 10 kPa absolute (90 kPa vacuum), enabled via integrated vacuum port and compatible with standard lab-grade diaphragm pumps.
Is third-party IQ/OQ validation support available?
Yes—comprehensive qualification documentation packages (including URS, FAT/SAT protocols, calibration certificates, and test records) are provided upon request for GxP-aligned installations.
How is ultrasonic energy distributed across large-volume batches (e.g., EX-TE-100)?
The system employs a dual-axis frame-mounted transducer array with adjustable immersion depth and synchronized anchor agitation, achieving ≥85% volumetric coverage at 20 kHz in 100 L batches per ASTM E2810-11 guidance.
Does the controller support remote monitoring?
Standard Ethernet (TCP/IP) and optional Wi-Fi modules enable secure remote access via HTTPS-enabled web interface, supporting real-time parameter viewing and alarm notifications via SMTP/SNMP protocols.
