Overview
The Wasserlab AUTWOMATIC PLUS is a modular, microprocessor-controlled ultra-pure water system engineered for consistent production of ASTM Type II and Type III laboratory water in demanding research, quality control, and routine analytical environments. Utilizing a dual-stage reverse osmosis (RO) core coupled with optional post-treatment modules—including ultraviolet (UV) irradiation at 254 nm and electrodeionization (EDI) or mixed-bed deionization (DI)—the system delivers water meeting stringent specifications for conductivity (<1 µS/cm), total organic carbon (<50 ppb with UV), and microbial load (<1 CFU/mL with 0.22 µm terminal filtration). Its architecture supports flexible deployment across benchtop and centralized lab configurations, with integrated pressure storage tanks (30 L or 50 L) enabling stable flow delivery independent of municipal supply fluctuations. Designed and manufactured in Spain, the AUTWOMATIC PLUS complies with ISO 9001-certified production standards and incorporates fail-safe monitoring logic aligned with GLP and GMP operational expectations.
Key Features
- 4.3-inch high-resolution capacitive touchscreen interface with intuitive icon-based navigation and multilingual support (English, Spanish, German, French)
- Dual-output capability: Simultaneous dispensing of Type II (RO + DI) and Type III (RO-only) water from independent outlets
- Real-time, multi-parameter monitoring including feed/RO/product conductivity, water temperature, UV lamp status, and pressure differentials across pre-filters, RO membranes, and DI cartridges
- Automated maintenance scheduling with visual and audible alerts for cartridge replacement (pre-filter, RO, DI, UV, 0.22 µm final filter), module cleaning cycles, and system diagnostics
- Programmable dispensing modes: volume-based, time-based, and continuous flow—each configurable with user-defined thresholds and audit-trail logging
- Integrated 30 L or 50 L pressurized storage tank with automatic pump start/stop logic to maintain constant delivery pressure (2–6 bar)
- Temperature-compensated conductivity measurement per IEC 60746-2, ensuring accuracy across ambient operating conditions (5–30 °C)
Sample Compatibility & Compliance
The AUTWOMATIC PLUS is validated for compatibility with standard laboratory feed water sources meeting EN 14880 and ASTM D1193-20 input requirements. It consistently produces water suitable for HPLC mobile phase preparation, buffer formulation, spectrophotometry, cell culture media dilution, and general glassware rinsing. The system supports compliance with ISO/IEC 17025 accreditation requirements through full parameter logging, timestamped event records, and user-accessible calibration history. Optional UV modules meet USP TOC validation criteria when paired with certified low-TOC tubing and fittings. All electrical components conform to CE marking directives (EMC 2014/30/EU, LVD 2014/35/EU), and mechanical design adheres to IP22 ingress protection classification.
Software & Data Management
Data integrity is maintained via embedded non-volatile memory storing >10,000 chronological events—including conductivity excursions, maintenance interventions, power cycles, and alarm acknowledgments—with UTC timestamps. The system supports optional USB export of CSV-formatted logs compatible with LIMS integration. While no proprietary cloud platform is included, raw data exports comply with FDA 21 CFR Part 11 principles when used in conjunction with institutional electronic signature policies and local network security protocols. Audit trails are immutable during active operation and retain full traceability for regulatory inspections under GLP, ISO 15189, or EU Annex 11 frameworks.
Applications
- Preparation of reagent-grade solutions for titration, pH calibration, and electrochemical analysis
- Feed water for steam generators, autoclaves, and environmental test chambers requiring low mineral content
- Source water for downstream purification systems (e.g., ultrapure water polishers for LC-MS or ICP-MS)
- Routine cleaning of analytical instruments (GC injectors, HPLC columns, pipette tips) where residue-free rinse water is critical
- Support of ISO 8573-1 Class 2 compressed air testing where condensate analysis requires low-conductivity rinse media
FAQ
What ASTM water types does the AUTWOMATIC PLUS produce?
It delivers both ASTM Type II (resistivity ≥1 MΩ·cm at 25 °C) and Type III (RO water, conductivity <5 µS/cm) simultaneously from dedicated outlets.
Is the system compliant with FDA 21 CFR Part 11?
The hardware supports Part 11 readiness via secure audit trails and exportable logs; full compliance requires institutional implementation of electronic signatures, access controls, and backup procedures.
Can the system operate with hard feed water?
Yes—up to 300 ppm CaCO₃ hardness—but requires periodic antiscalant dosing or softening pretreatment to prevent RO membrane fouling.
What maintenance intervals are recommended for consumables?
Pre-filters: every 3–6 months; RO membranes: 2–3 years depending on feed quality; DI cartridges: 6–12 months; UV lamps: annually; 0.22 µm filters: per batch or weekly in high-use labs.
Does the unit include remote monitoring capability?
No built-in Ethernet or Wi-Fi interface is provided; however, analog voltage outputs (0–10 V) for conductivity and pressure are available for integration into facility SCADA systems.
