Overview
The SXT-06 Soxhlet Extractor is a benchtop solvent extraction system engineered for precise, reproducible fat and lipid determination in accordance with standardized gravimetric methodologies. It operates on the classical Soxhlet principle—cyclic percolation of hot solvent through a solid sample matrix housed in a thimble, followed by condensation and return of condensed solvent to the extraction chamber. This continuous reflux process ensures exhaustive extraction of analytes soluble in organic solvents (e.g., petroleum ether, diethyl ether, or hexane), minimizing manual intervention while maximizing extraction efficiency. Designed for routine quality control and compositional analysis in regulated environments, the SXT-06 integrates thermal regulation, automatic solvent recovery, and timed endpoint signaling—features aligned with AOAC Official Method 920.39, ISO 6496:1999, and GB/T 5512–2008 for cereal and feed analysis.
Key Features
- Six independent extraction channels enable parallel processing of up to six samples, improving throughput without cross-contamination risk.
- Precise digital temperature control (±1 °C accuracy) across a range of +5 °C above ambient to 100 °C supports method flexibility for solvents with varying boiling points (e.g., petroleum ether bp ~40–60 °C; chloroform bp ~61 °C).
- Integrated solvent recovery circuit condenses and returns vaporized solvent directly to the heating flask, reducing reagent consumption by >90% and minimizing exposure to volatile organic compounds (VOCs).
- Programmable extraction timer with audible end-of-cycle alarm ensures consistent dwell time and eliminates operator dependency in endpoint determination.
- Robust stainless steel and borosilicate glass construction complies with laboratory safety standards for chemical resistance and thermal stability under prolonged heating cycles.
- Front-accessible design facilitates rapid loading/unloading of extraction thimbles and flasks; no tools required for routine maintenance.
Sample Compatibility & Compliance
The SXT-06 accommodates solid or semi-solid matrices with fat content ranging from 0.5% to 60%, including cereal grains, oilseeds (e.g., soybean, rapeseed), animal feeds, bakery products, and processed foodstuffs. Each 150 mL extraction flask is calibrated to ASTM E177 tolerances for volumetric accuracy. The system meets mechanical and electrical safety requirements per GB 4793.1–2019 (equivalent to IEC 61010-1) and supports GLP-compliant workflows when paired with documented SOPs and instrument logbooks. While not inherently 21 CFR Part 11 compliant, its operation is fully auditable via manual entry logs and time-stamped extraction records.
Software & Data Management
The SXT-06 operates as a standalone hardware platform with no embedded firmware or proprietary software. All operational parameters—including setpoint temperature, duration, and cycle count—are configured via tactile rotary dial and LED display. Users maintain full traceability through paper-based or LIMS-integrated batch records documenting sample ID, solvent type, extraction time, and final residue weight. For laboratories requiring electronic data capture, integration with external balance interfaces (RS-232 or USB) enables direct transfer of post-extraction dried residue mass into spreadsheet or validated QA/QC databases.
Applications
- Routine fat quantification in agricultural commodities per AOAC 991.36 and ISO 1444–1:2001.
- Crude fat analysis in compound animal feeds for nutritional labeling compliance (EU Regulation No. 767/2009).
- Quality assurance testing of edible oils and oilseed meals during production and storage.
- Method validation studies comparing extraction efficiency across solvent systems and particle size distributions.
- Educational use in university analytical chemistry and food science laboratories for teaching classical extraction principles.
FAQ
What solvents are compatible with the SXT-06?
Petroleum ether (40–60 °C fraction), diethyl ether, hexane, chloroform, and dichloromethane may be used, provided their boiling points fall within the instrument’s controllable temperature range and flash points exceed the operating surface temperature.
Is the SXT-06 suitable for regulatory submissions?
Yes—when operated per validated SOPs and supported by calibration certificates for balances and thermometers, data generated meets evidentiary requirements for ISO/IEC 17025-accredited testing laboratories.
Can extraction time be extended beyond factory presets?
Yes—the timer is fully user-adjustable; typical extraction durations range from 4 to 16 hours depending on sample matrix density and target analyte solubility.
How often should the cooling water flow rate be verified?
Daily verification is recommended prior to first use; minimum flow rate of 1.5 L/min at 15–25 °C inlet temperature ensures full condensation efficiency and prevents solvent loss.
Does the unit include extraction thimbles or flasks?
No—standard 25 × 80 mm cellulose thimbles and 150 mL round-bottom extraction flasks must be sourced separately to match method-specific requirements.
