Savillex DST-1000 Sub-Boiling Acid Distillation System

Overview

The Savillex DST-1000 Sub-Boiling Acid Distillation System is an ultra-high-purity acid purification instrument engineered for trace-metal analysis laboratories requiring reagent-grade acids with sub-part-per-trillion (sub-ppt) metallic contamination levels. Operating on the principle of sub-boiling distillation—where acidic solutions are heated below their atmospheric boiling point to minimize aerosol entrainment and volatile impurity carryover—the DST-1000 achieves exceptional separation efficiency for HCl, HNO₃, HF, and HBr. Its fully enclosed, PFA-only fluid path eliminates leaching from glass, quartz, or metal components, making it suitable for sample preparation workflows supporting ICP-MS, ICP-OES, HR-ICP-MS, and EPA Method 200.2–compliant environmental testing. Designed for integration into Class 100 clean benches or standard fume hoods, the system occupies less than 0.1 m² footprint and requires no external cooling water, reducing infrastructure dependency and operational overhead.

Key Features

• Monolithic molded PFA construction for all wetted surfaces—including evaporator chamber, condenser, collection vessel, and funnel—ensuring zero extractables and maximum chemical inertness toward aggressive mineral acids.
• Integrated resistive heating jacket wrapped directly around the PFA evaporator, enabling precise thermal control without open flames, halogen lamps, or corrosion-prone external heaters.
• Passive air-cooling condenser design eliminates reliance on recirculating chillers or tap-water cooling loops—reducing energy consumption, noise, and risk of cross-contamination from coolant leaks.
• Automated endpoint detection via integrated temperature monitoring and thermal hysteresis logic, terminating distillation when residual volume reaches user-defined thresholds (e.g., 5–10 mL), preventing dry-out and ensuring reproducible yield.
• Modular, tool-free assembly with snap-fit PFA components facilitates rapid cleaning, inspection, and validation—critical for GLP/GMP-regulated environments.
• Adjustable power output (0–100% via front-panel dial) allows fine-tuning of distillation rate to balance throughput and purity requirements across varying acid matrices and volumes.

Sample Compatibility & Compliance

The DST-1000 supports high-purity purification of hydrochloric acid (HCl), nitric acid (HNO₃), hydrofluoric acid (HF), and hydrobromic acid (HBr) at concentrations ranging from 1–12 M. It is validated for use in applications governed by ASTM D511 (trace metals in water), ISO 17294-2 (water quality—ICP-MS methods), USP (conductivity of purified water), and EPA Methods 200.2 and 6020B. All PFA components comply with USP Class VI biocompatibility standards and meet RoHS and REACH material restrictions. When paired with Savillex’s certified PFA storage bottles (DST-BOTTLE series), the full workflow—from distillation to long-term storage—maintains trace-metal integrity under ISO/IEC 17025-accredited laboratory conditions.

Software & Data Management

While the DST-1000 operates as a standalone analog-controlled instrument, optional digital retrofit kits (DST-DIGI-Kit v2.1) provide RS-232/USB connectivity and PC-based logging of real-time temperature, elapsed time, and power setting. The accompanying Savillex DistillLog™ software supports 21 CFR Part 11-compliant audit trails, electronic signatures, and configurable alarm thresholds—enabling full traceability for regulated QC/QA labs conducting ISO 17025 method validation or pharmaceutical raw material qualification per ICH Q5C guidelines.

Applications

• Preparation of ultrapure calibration standards and matrix-matched blanks for multi-element ICP-MS analysis in geochemical, nuclear, and semiconductor metrology labs.
• Acid digestion blank reduction in EPA SW-846 Method 3050B and 3052 workflows for soil, sediment, and biological tissue analysis.
• Production of low-background acids for uranium/thorium isotope ratio measurements (TIMS, MC-ICP-MS) where Pb, U, and Th contamination must remain below 0.1 pg/g.
• Supporting CLIA-certified clinical toxicology labs performing heavy metal screening in whole blood and urine via ICP-OES.
• On-demand generation of high-purity acids in field-deployable clean labs (e.g., Antarctic research stations, mobile environmental monitoring units).

FAQ

What acids are compatible with the DST-1000?
Hydrochloric acid (HCl), nitric acid (HNO₃), hydrofluoric acid (HF), and hydrobromic acid (HBr) are validated for use. Sulfuric and phosphoric acids are not recommended due to thermal decomposition risks and PFA compatibility limits.
Does the DST-1000 require plumbing or external cooling?
No. It uses passive air cooling only and operates independently of water lines, chillers, or compressed air—ideal for temporary setups or space-constrained fume hoods.
How often does the system require maintenance?
Under normal operation, routine cleaning with high-purity rinse acid every 10–15 runs is sufficient; PFA components have a service life exceeding 5 years with proper handling and avoidance of mechanical abrasion.
Can the DST-1000 be validated for GMP compliance?
Yes. With optional digital logging, IQ/OQ documentation packages, and third-party calibration certificates (NIST-traceable thermocouple verification), it meets Annex 11 and ALCOA+ data integrity requirements.
Is operator training included with purchase?
Savillex provides remote installation support and application-specific SOP templates; on-site training is available upon request through authorized distributors.
