Analab EvapoClean® 12-Position Sub-Boiling Distillation System (12 × 125 mL)

Overview

The Analab EvapoClean® 12-Position Sub-Boiling Distillation System is an engineered solution for ultra-trace and high-purity reagent purification in analytical, nuclear, environmental, and semiconductor-grade laboratories. Unlike conventional boiling distillers, this system operates below the atmospheric boiling point—typically 5–15 °C below—enabling gentle, non-turbulent phase transition that prevents aerosol carryover, elemental fractionation, or thermal decomposition of volatile analytes. The process relies on precise thermal control of a PFA-coated heating surface, where solvent evaporation occurs under inert, closed-loop conditions; vapor is directed through cooled PFA-lined pathways and condensed exclusively in thermally isolated collection zones, ensuring zero back-contamination. Designed for compatibility with HF, HNO₃, HCl, and aqua regia, it meets stringent requirements for trace-metal-free acid preparation per ASTM D512, ISO 17025, and USP water purity guidelines.

Key Features

• Sub-boiling operation with digitally regulated temperature control (range: 60–120 °C, resolution: 0.1 °C) to eliminate bumping, splashing, and elemental volatility loss.
• 12-position modular configuration accommodating standard 125 mL quartz or PFA digestion vessels—each seated in individually sealed, acid-resistant PFA gasketed wells.
• 400 µm uniform PFA coating applied via electrostatic spray and sintered at >380 °C, providing full inertness against aggressive mineral acids and preventing metal leaching (validated per ASTM F2219).
• Integrated side-shielded heating plate with embedded Pt100 sensor array ensures ±0.5 °C spatial uniformity across the entire surface—critical for parallel sample reproducibility.
• External temperature controller mounted outside fume hoods via 1.7 m PFA-sheathed cable, enabling safe, uninterrupted operation under GLP/GMP audit conditions.
• Hermetically sealed vapor path with passive condensation manifold; no moving parts, pumps, or refrigerants required—reducing failure points and maintenance overhead.

Sample Compatibility & Compliance

The EvapoClean® system is validated for use with ultrapure-grade acids (e.g., Optima™, TraceSELECT®, and Seastar™), including hydrofluoric, nitric, hydrochloric, perchloric, and mixed acids. All wetted surfaces—including vessel holders, condensate channels, and collection reservoirs—are constructed from or coated with fluoropolymer materials compliant with FDA 21 CFR 177.1550 and EU Regulation (EC) No. 1935/2004. Each unit undergoes individual cleanroom acceptance testing per ISO 14644-1 Class 1 protocols, with particulate and metallic contamination levels verified using ICP-MS (detection limit ≤0.1 pg/mL for Cr, Ni, Cu, Zn, Cd, Pb). Documentation includes full traceability of coating batch certification, thermal mapping reports, and third-party validation summaries suitable for FDA 21 CFR Part 11-compliant environments.

Software & Data Management

While the base model operates via analog-digital hybrid control (no embedded firmware), optional RS-485/Modbus RTU interface enables integration into centralized laboratory informatics systems (LIMS or ELN). Temperature setpoints, ramp profiles, hold durations, and real-time surface readings can be logged externally with timestamped audit trails. For regulated labs, the external controller supports configurable alarm thresholds (e.g., overtemperature, open-circuit detection) with relay outputs for interlock with hood airflow monitors or emergency shutoff circuits—fully aligned with IEC 61511 functional safety standards.

Applications

• Preparation of sub-part-per-trillion (sub-ppt) blank acids for ICP-MS, GD-MS, and TIMS analysis in geochemical and nuclear forensics labs.
• Purification of reagents used in semiconductor wafer cleaning (SEMI F57 compliance) and photomask fabrication.
• Generation of certified reference material (CRM) diluents for EPA Method 200.8 and ISO/IEC 17025-accredited environmental testing.
• Recovery and reuse of high-value solvents (e.g., HF/HNO₃ mixtures) in spent etchant recycling workflows—reducing hazardous waste generation by >70% versus single-use disposal.
• On-demand production of ultra-low-background acids for low-radiation physics experiments (e.g., dark matter detector calibration).

FAQ

Is fume hood installation mandatory?
Yes. Although the system operates in a sealed vapor path, local ventilation is required per OSHA 1910.1200 and ANSI Z9.5 to mitigate potential seal degradation or incidental leakage during vessel loading/unloading.
Can I use glass or quartz vessels instead of PFA?
Quartz vessels are permitted for HNO₃ and HCl applications; however, HF-containing solutions require PFA or PTFE-lined vessels due to quartz etching—vessel compatibility must be confirmed against Analab’s chemical resistance matrix.
What maintenance is required?
No routine maintenance is needed beyond periodic visual inspection of PFA seals and cleaning of condensate traps with 18.2 MΩ·cm DI water; the fully encapsulated heater assembly is rated for >10,000 hours of continuous operation.
Does the system support variable-volume evaporation?
Yes—individual well temperature profiles can be adjusted manually or via optional multi-zone controller to accommodate differing initial volumes (25–125 mL) while maintaining consistent evaporation kinetics across all positions.
How is calibration performed?
Each unit ships with NIST-traceable temperature calibration certificate; field verification uses a calibrated Pt100 probe inserted into designated test ports—no disassembly required.
