Overview
The Wasserlab AUTWOMATIC Economy Ultra-Pure Water System is a compact, integrated laboratory water purification platform engineered for reliable production of ASTM Type II and Type III purified water. Designed in accordance with ISO 3696:1987 and aligned with CLSI EP21-A guidelines for water quality verification, the system employs a multi-stage purification architecture: pre-filtration (sediment + activated carbon), reverse osmosis (RO), and optional post-RO deionization (DI) to achieve consistent conductivity values below 1 µS/cm for Type II water. Its modular configuration supports scalable output capacities—30, 50, or 100 liters per day—making it suitable for routine analytical support in QC laboratories, teaching facilities, and low-to-moderate throughput research environments where regulatory traceability and operational simplicity are prioritized over ultra-trace elemental purity.
Key Features
- Integrated dual-grade output: Simultaneous delivery of ASTM Type II water (conductivity <1 µS/cm) and Type III RO water from a single chassis
- Intuitive membrane keypad interface with real-time parameter display—no touchscreen required; optimized for glove-compatible operation and long-term reliability
- Self-pressurized RO storage tank (30 L or 50 L variants) eliminates need for external air compressors or booster pumps
- Comprehensive sensor-based monitoring: feed water conductivity, RO permeate conductivity, product water conductivity, water temperature, operating hours, and system pressure differentials
- Automated maintenance alerts: scheduled notifications for pre-filter replacement, RO membrane service, and DI cartridge exhaustion based on runtime and conductivity drift thresholds
- Fail-safe operational logic: automatic shutdown upon feed pressure loss, tank overfill, temperature excursion (>30 °C), or conductivity breach beyond user-defined limits
- Temperature-compensated conductivity measurement (per ASTM D1125) ensures accuracy across ambient lab conditions (15–25 °C)
Sample Compatibility & Compliance
The AUTWOMATIC system is validated for continuous generation of water meeting ASTM D1193-20 (Type II and Type III), ISO 3696:1987 (Grade 2 and Grade 3), and CLSI EP21-A (for general laboratory use). It is not intended for preparation of USP Purified Water or WFI, nor does it comply with FDA 21 CFR Part 11 requirements for electronic records without supplemental audit-trail software. Feed water must conform to municipal potable standards per EN 14899:2006 or local drinking water regulations. The unit’s materials of construction—including food-grade polypropylene housings, TFC RO membranes, and mixed-bed DI resins—are certified non-leaching per USP and do not introduce detectable organics (TOC 0.22 µm) under nominal operating conditions.
Software & Data Management
The AUTWOMATIC operates via embedded firmware with no external PC dependency. All operational data—including conductivity logs, maintenance timestamps, alarm history, and runtime counters—are stored locally in non-volatile memory and accessible via the front-panel interface. While the system does not provide USB export, CSV download, or network connectivity, its event-driven alerting structure (visual LED indicators + audible beeps) satisfies GLP documentation prerequisites for manual logbook entry. Each alarm code corresponds to a defined failure mode (e.g., “AL-04” = DI exhaustion; “AL-07” = feed pressure drop), enabling rapid root-cause assessment during routine QA audits.
Applications
- Feed water supply for autoclaves, glassware washers, and steam generators requiring Type III water
- Solvent and reagent preparation for HPLC mobile phase blending, buffer dilution, and spectrophotometric calibration (Type II grade)
- General laboratory cleaning, rinsing, and equipment feed in academic teaching labs and clinical support units
- Preparation of media and diluents in microbiology workflows compliant with ISO 11133:2014
- Supporting non-critical instrumentation such as pH meters, conductivity probes, and basic electrochemical cells
FAQ
Does the AUTWOMATIC system meet ISO 15195 requirements for reference laboratory water?
No. ISO 15195 applies exclusively to calibration laboratories using water as a metrological reference standard; the AUTWOMATIC is designed for general-purpose laboratory use per ISO 3696.
Can the unit be connected to a central lab water distribution loop?
Not recommended. The AUTWOMATIC lacks pressure-regulated recirculation capability and is intended for point-of-use deployment only.
Is the RO membrane certified to NSF/ANSI Standard 58?
Yes—the installed thin-film composite (TFC) membrane carries NSF/ANSI 58 certification for reduction of total dissolved solids (TDS), sodium, and heavy metals under specified feed conditions.
What is the expected service life of the DI cartridge under typical lab usage?
At 5 L/h continuous draw and feed conductivity of 300 µS/cm, mixed-bed DI cartridges typically last 6–9 months before conductivity exceeds 1 µS/cm; lifespan decreases proportionally with higher feed ion load.
Does the system include validation documentation for IQ/OQ protocols?
A factory-assembled performance qualification report (including conductivity, flow rate, and pressure test results) is supplied. Full IQ/OQ templates compatible with GMP Annex 15 are available upon request but require on-site execution by qualified personnel.
