EURPING Acide 3200 Sub-Boiling Acid Vapor Ultra-Clean Laboratory Glassware Cleaner

Overview

The EURPING Acide 3200 is a fully automated sub-boiling acid vapor ultra-clean laboratory glassware cleaner engineered for trace-element analytical laboratories requiring ultra-low background contamination control. It operates on the principle of controlled sub-boiling acid vapor generation—where high-purity acids (e.g., HNO₃, HCl, HF) are heated below their atmospheric boiling points to produce saturated, low-velocity vapor that condenses unidirectionally onto vessel surfaces. This condensate forms a continuous, non-turbulent liquid film that solubilizes and transports adsorbed metal cations (e.g., Cr, Ni, Pb, Al, Fe) and inorganic residues from both internal and external surfaces of labware. Unlike conventional reflux or immersion methods, the Acide 3200 avoids thermal decomposition of acids and minimizes aerosol carryover—critical for ICP-MS, HR-ICP-MS, and graphite furnace AAS workflows where blank levels must remain below 0.1 pg/mL for key analytes.

Key Features

• Sub-boiling acid vapor generation with precision temperature ramping: 0–90 °C in ≤5 min; stabilized at 95 °C within 10 min to maintain optimal vapor saturation without acid decomposition.
• Unidirectional, non-recirculating acid vapor path combined with single-pass ultrapure water (≥18.2 MΩ·cm, TOC < 1 ppb) spray rinse—eliminates cross-contamination from residual acid carryover or recirculated rinse water.
• Integrated EP (Enhanced Protection) acid gas absorption system with active exhaust fan and neutralizing media (e.g., NaOH-impregnated alumina), ensuring no detectable acid vapor leakage (tested per ISO 10155:2021 workplace exposure limits).
• Fully automated acid dosing and drainage: real-time conductivity-based liquid level sensing triggers acid replenishment alerts; programmable drain sequence ensures complete acid evacuation prior to rinse phase.
• Dual-layer borosilicate viewing door with magnetic seal and pressure-relief interlock—enables real-time visual monitoring while maintaining Class II containment integrity during operation.
• Neutralized wastewater discharge (pH 6.5–7.5) compliant with local municipal pretreatment standards; no post-treatment required prior to sewer release.

Sample Compatibility & Compliance

The Acide 3200 accommodates a broad range of trace-analysis consumables: quartz, borosilicate glass, PFA, PTFE, and TFM vials (up to 1000 mL capacity); digestion tubes (e.g., SCP Science, Savillex®); volumetric flasks; Erlenmeyer flasks; and ICP-MS sample introduction components (nebulizers, spray chambers, torch injectors). All wetted materials are chemically inert to concentrated HNO₃, HCl, and diluted HF (≤2%). The system meets design requirements aligned with ISO/IEC 17025:2017 clause 6.4.3 (equipment suitability for intended use), supports GLP audit readiness via full cycle logging, and facilitates compliance with USP , EPA Method 1638, and ASTM D5673-22 for low-level metals analysis preparation.

Software & Data Management

The embedded controller runs firmware v3.2+ with password-protected user roles (Operator, Supervisor, Administrator). Each cleaning cycle generates an immutable digital log containing timestamp, acid type/lot, temperature profile, rinse duration, exhaust flow rate, and EP system status—exportable as CSV or PDF. Audit trail functionality complies with FDA 21 CFR Part 11 requirements (electronic signatures, event logging, data integrity controls). Optional Ethernet/Wi-Fi module enables remote monitoring and integration into LIMS via RESTful API.

Applications

• Preparation of ultra-clean sample introduction hardware for ICP-MS and triple-quadrupole ICP-MS instrumentation.
• Decontamination of calibration standards vessels to prevent memory effects in multi-element quantitation.
• Routine cleaning of high-value quartz ICP torches and nickel sampler/skimmer cones.
• Blank reduction in environmental testing labs performing EPA SW-846 Methods 6020B and 6025A.
• Supporting clinical trace-metal assays (e.g., serum Cu/Zn ratios) where matrix interference must be minimized.

FAQ

What acid types are compatible with the Acide 3200?
Concentrated nitric acid (69%), hydrochloric acid (37%), and hydrofluoric acid (≤2%) are validated; other high-purity mineral acids may be used subject to compatibility verification.
Does the system require external ventilation ducting?
No—integrated EP acid gas absorption eliminates need for hard-ducted fume hood connection; standalone installation is permitted per ANSI Z9.5-2022.
How is cleaning efficacy verified?
Users perform periodic blank testing using certified reference materials (e.g., NIST SRM 1643e) processed through the Acide 3200; typical post-cleaning blanks achieve ≤0.05 pg/mL for Co, Ni, Cu, Zn, Cd, and Pb.
Can the Acide 3200 clean assembled ICP-MS nebulizer assemblies?
Yes—customizable rack fixtures accommodate complete nebulizer bodies (e.g., MicroMist®, PFA-ST) without disassembly, preserving calibration integrity.
Is maintenance documentation available in English?
Yes—full technical manual, preventive maintenance schedule, and service bulletins are provided in English and updated quarterly via EURPING’s secure customer portal.
