GLOBUS DF Series Steam Distillation Apparatus

Overview

The GLOBUS DF Series Steam Distillation Apparatus is a purpose-engineered system for the gentle, selective isolation of thermolabile volatile compounds—particularly essential oils, aromatic fractions, and bioactive phytochemicals—from botanical matrices including medicinal herbs, traditional Chinese herbs, fruits, flowers, and resinous plant materials. Operating on the principle of steam distillation, the apparatus introduces saturated low-pressure steam directly into the sample chamber, lowering the partial pressure of volatile constituents and enabling their co-distillation at temperatures significantly below their atmospheric boiling points. This minimizes thermal degradation and preserves molecular integrity—critical for pharmaceutical-grade extracts, fragrance isolates, and analytical reference standards. Designed for continuity across R&D, process development, and pilot-scale production, the DF Series bridges laboratory validation and scalable manufacturing under regulated environments.

Key Features

• FDA- and GMP-compliant construction using electropolished 316L stainless steel throughout all wetted surfaces—including vessel, steam inlet manifold, condenser housing, and collection interface—to ensure corrosion resistance, cleanability, and compliance with USP , EU Annex 1, and ISO 14644-1 Class 5/7 requirements.
• Internally integrated condensation chamber positioned concentrically within the main distillation vessel, eliminating external vapor transfer lines and reducing residence time and surface adsorption losses—particularly critical for high-value, low-yield terpenes and aldehydes.
• Double-jacketed borosilicate glass separatory funnel with independent thermal control of inner and outer jackets (±0.5 °C stability), enabling precise phase separation between aqueous distillate and immiscible essential oil layers while preventing emulsion formation or recondensation.
• Closed-loop water circulation system with PID-controlled chiller integration, maintaining consistent condenser temperature (typically 2–8 °C) across variable ambient conditions and extended run durations (>8 h).
• Real-time thermal monitoring via calibrated heat meter (traceable to NIST standards) and dual redundant safety architecture: primary ASME Section VIII Div. 1 safety valve plus secondary overpressure relief port with rupture disc.

Sample Compatibility & Compliance

The DF Series accommodates heterogeneous solid–liquid botanical feedstocks—including dried/crushed herbs, fresh floral material, citrus peels, and powdered rhizomes—without requiring pre-solvent extraction or mechanical homogenization. Its steam-permeable basket design ensures uniform vapor distribution and avoids channeling or localized overheating. All models are supplied with full material traceability documentation (EN 10204 3.1), weld procedure specifications (WPS), and as-built dimensional drawings. The system supports qualification protocols per IQ/OQ/PQ frameworks and is compatible with 21 CFR Part 11–compliant electronic record systems when interfaced with validated SCADA or LIMS platforms.

Software & Data Management

While the base DF configuration operates via analog instrumentation and manual setpoints, optional digital control modules integrate programmable logic controllers (PLCs) with HMI touchscreens supporting recipe-based operation, real-time parameter logging (temperature, pressure, flow, accumulated distillate volume), and CSV export. Audit trails comply with ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available), satisfying GLP and GMP data integrity expectations. Remote diagnostics and firmware updates are supported via secure Ethernet (TLS 1.2) connections.

Applications

• Isolation of pharmacopoeial-grade essential oils (e.g., lavender, eucalyptus, peppermint) meeting EP/USP monograph specifications.
• Recovery of fragrance headspace fractions for perfumery R&D and natural aroma compound standardization.
• Preparative-scale extraction of volatile alkaloids (e.g., nicotine, coniine) and sulfur-containing volatiles (e.g., allicin derivatives) from Allium spp.
• Process validation studies for herbal drug master files (DMFs) submitted to EMA or FDA CDER.
• Teaching laboratories conducting green chemistry experiments on solvent-free separation techniques aligned with ACS Green Chemistry Institute metrics.

FAQ

What regulatory certifications does the DF Series carry?**
The apparatus is constructed to meet FDA 21 CFR Parts 110 and 113 requirements for food/pharma contact surfaces and complies with GMP Annex 15 for equipment qualification. CE marking (PED 2014/68/EU, EMC 2014/30/EU) is standard; additional certifications (e.g., UL, CSA) can be arranged per regional market requirements.
Can the system operate continuously for >24 hours?**
Yes—when equipped with automated feed and overflow management (optional), the DF Series supports unattended batch operation up to 72 hours with scheduled cooling cycles and thermal drift compensation.
Is validation support provided?**
GLOBUS supplies comprehensive URS templates, FAT/SAT protocols, and commissioning checklists. On-site IQ/OQ execution by certified engineers is available under separate service agreement.
What maintenance intervals are recommended?**
Routine inspection of gasket integrity and steam trap functionality every 200 operating hours; full calibration of heat meter and safety valve annually or per ISO/IEC 17025-accredited schedule.
Are spare parts and technical documentation available in English?**
All OEM spares—including custom-machined glassware, diaphragm seals, and PLC I/O modules—are stocked globally. Full English-language manuals (operation, maintenance, electrical schematics, P&ID) are delivered digitally and on USB upon shipment.
