Overview
The Drick DRK-SOX316 Six-Channel Soxhlet Fat Analyzer is a precision-engineered benchtop extraction system designed for quantitative determination of lipid content and other extractable organic compounds using the classical Soxhlet principle—continuous solvent reflux and cyclic percolation through solid samples. Based on gravimetric or volumetric quantification post-extraction and solvent evaporation, it delivers high reproducibility in compliance with internationally recognized analytical standards including ISO 6496, AOAC 920.39, and ASTM D2231. Its modular six-channel architecture enables parallel processing of up to six independent samples under identical thermal and fluidic conditions, significantly improving throughput while maintaining inter-channel consistency. The instrument employs a fully enclosed, solvent-resistant flow path constructed from borosilicate glass and PTFE-sealed components, ensuring chemical inertness across chlorinated, ether-based (e.g., diethyl ether, petroleum ether), aromatic (e.g., benzene, toluene), and ketonic solvents.
Key Features
- Six independent extraction channels with individual temperature and timing control, supporting true parallel operation without cross-contamination.
- Embedded metal heating block design delivering rapid thermal response (≤15 min to reach 100°C), stable temperature uniformity (±1°C), and energy-efficient operation (2.0 kW total rated power).
- Integrated solvent leakage detection system with real-time ethereal vapor monitoring, triggering audible/visual alarms and automatic heater shutdown upon threshold exceedance.
- Full-spectrum solvent compatibility: validated for use with diethyl ether, petroleum ether, chloroform, hexane, acetone, and toluene—enabled by PTFE gaskets and all-glass condenser/extraction tube assemblies.
- Vertical Android-style touchscreen controller (wall-mountable) featuring intuitive icon-driven navigation, preloaded method templates (GB 5009.6–2016, GB/T 6433–2006, AOAC 991.36), and one-touch start/pause functionality.
- Dual-point water cooling management: inlet/outlet temperature sensors coupled with proportional flow control ensure optimal condensation efficiency while reducing water consumption by up to 40% versus conventional systems.
- Automated solvent recovery module with >85% recovery rate, minimizing reagent cost and environmental discharge load.
- Real-time system diagnostics—including cooling water presence verification, heater status, solvent level sensing, and overtemperature protection—integrated into the controller’s status dashboard.
Sample Compatibility & Compliance
The DRK-SOX316 accommodates solid and semi-solid matrices within a 0.5–15 g mass range, including but not limited to foodstuffs (meat, dairy, cereals), agricultural feedstuffs, soil and sediment samples, pharmaceutical excipients, and industrial cleaning agents. It supports both gravimetric and solvent-evaporation-based quantification workflows. All operational protocols align with GLP documentation requirements, and the controller logs timestamped event records (method start/end, temperature setpoints, alarm triggers) suitable for audit trails. The system conforms to national and international fat analysis standards including GB 5009.6–2016 (Food Safety National Standard – Determination of Fat in Foods), GB/T 6433–2006 (Crude Fat in Feeds), GB/T 9695.1–2008 (Free Fat in Meat Products), and ISO 1444–1999 (Animal Feeding Stuffs – Determination of Ether Extract). No modifications are required to meet routine QC/QA validation criteria under ISO/IEC 17025.
Software & Data Management
The embedded controller runs a deterministic real-time OS with localized UI language support (English default). Method parameters—including extraction mode (Classical Soxhlet, Hot Continuous Extraction, Reflux-Only, Flow-Through, or CH-Standard Hot Extraction), cycle count, heating ramp profile, and dwell time—are stored as encrypted .mth files. Each run generates a timestamped CSV report containing channel ID, start/stop times, peak temperature, solvent volume consumed (estimated), and operator ID (if configured via optional network login). Data export is supported via USB 2.0 port; no cloud connectivity or proprietary software installation is required. Audit-ready logs comply with FDA 21 CFR Part 11 principles when used in conjunction with institutional electronic signature policies.
Applications
- Quantitative fat analysis in meat, dairy, baked goods, and infant formula per regulatory food safety testing mandates.
- Crude fat determination in animal feed and aquaculture formulations according to AOAC and ISO protocols.
- Extraction of hydrophobic contaminants (e.g., PAHs, PCBs, organochlorine pesticides) from soil, sludge, and wastewater solids for environmental monitoring.
- Isolation of active lipophilic compounds (e.g., tocopherols, sterols, essential oils) in botanical and pharmaceutical raw materials.
- Method development and validation studies requiring multi-parameter optimization across solvent type, temperature, and cycle duration.
FAQ
What extraction modes does the DRK-SOX316 support?
It offers five programmable modes: Classical Soxhlet (standard reflux-percolation), Hot Continuous Extraction, Reflux-Only (no percolation), Flow-Through (solvent continuously fed), and CH-Standard Hot Extraction (optimized for rapid lipid release).
Can the system be used with halogenated solvents such as chloroform or dichloromethane?
Yes—the entire fluid path (extraction thimbles, condensers, receiving flasks, and seals) is chemically resistant to halogenated, ether, aromatic, and ketonic solvents per material certification data.
Is the controller compatible with laboratory LIMS integration?
While native LIMS interface is not built-in, CSV output files can be parsed by third-party middleware; custom RS-232 or Ethernet communication modules are available upon request for OEM integration.
What maintenance intervals are recommended for long-term reliability?
Glassware should be inspected for etching or cracking before each use; PTFE gaskets require replacement every 6–12 months depending on solvent aggressiveness and cycle frequency. Heating block calibration is advised annually using NIST-traceable thermocouples.
Does the instrument include provisions for fume hood integration?
Yes—it features dedicated solvent vapor vent ports compatible with standard 50 mm ducting, and its sealed condensation system minimizes fugitive emissions when operated inside certified chemical fume hoods.
