HHitech Eco-Q Series Ultra-Pure Water System

Overview

The HHitech Eco-Q Series Ultra-Pure Water System is an integrated, laboratory-grade water purification platform engineered for consistent production of Type I ultrapure water per ASTM D1193, ISO 3696, and GB/T 6682-2008 standards. It employs a multi-stage purification architecture combining prefiltration (5 μm PP + KDF + coconut-shell activated carbon), high-rejection reverse osmosis (RO) using Dow FilmTec™ membrane elements, dual-stage deionization (DI) with nuclear-grade ion-exchange resins, 254 nm UV photooxidation, and terminal sterilizing filtration. The system accepts municipal tap water as feedstock (TDS ≤ 200 ppm, 5–45 °C, 1.0–4.0 bar), delivering ultrapure water at up to 30 L/h with real-time resistivity monitoring ≥18.2 MΩ·cm and TOC <3 ppb — meeting stringent requirements for HPLC, LC-MS, cell culture, molecular biology, and trace elemental analysis.

Key Features

• Intelligent microprocessor control with backlit LCD interface and animated operational flow visualization
• Dual-channel real-time water quality monitoring: TDS (RO permeate) and resistivity (DI effluent)
• Automated RO membrane antiscalant flushing cycle (every 2 hours) plus manual override for extended membrane service life
• Comprehensive consumables management: programmable lifetime tracking for prefilter, RO membrane, UV lamp, and DI cartridges with visual countdown and end-of-life alerts
• Multi-mode dispensing: manual, timed (1–99 min), and quality-triggered (0.1–18.2 MΩ·cm) delivery
• Two independent touch-activated outlets: dedicated RO and DI water ports
• Factory- and user-configurable password protection (dual-level access) compliant with GLP audit requirements
• Integrated 12 L NSF-certified pressure tank minimizing footprint and eliminating need for external storage
• Full engineering plastic chassis with electrical/water separation, corrosion-resistant design, and ergonomic form factor
• NSF-certified fluid path components (tubing, fittings, housings); low-TOC materials throughout wetted surfaces

Sample Compatibility & Compliance

The Eco-Q Series is validated for continuous operation in regulated research and quality control environments. Its output meets or exceeds the purity specifications required for ISO/IEC 17025-accredited testing laboratories and complies with key regulatory frameworks including USP for TOC, USP for endotoxin, and CLSI EP21-A for water quality verification. All consumables — including Dow FilmTec™ RO membranes, nuclear-grade mixed-bed resins, and PES-based 0.45 + 0.1 μm terminal filters — are manufactured under strict quality control and carry material traceability documentation. The system supports full audit trail generation for maintenance logs, alarm events, and parameter changes — facilitating FDA 21 CFR Part 11 readiness when paired with optional data logging software.

Software & Data Management

While the Eco-Q operates as a standalone instrument, its embedded firmware supports time-stamped event logging (e.g., alarm triggers, consumable replacements, calibration actions) stored internally for ≥12 months. Optional USB data export enables integration into laboratory information management systems (LIMS) or electronic lab notebooks (ELN). The system’s alarm architecture distinguishes between critical (e.g., low feed pressure, resistivity deviation >0.1 MΩ·cm, tank overfill) and advisory conditions (e.g., 10% remaining resin capacity), each mapped to discrete LED indicators (RUN / ALARM / FULL). All configuration parameters — including setpoints, flush intervals, and password policies — are protected by dual-layer authentication to ensure data integrity and procedural consistency across shifts and users.

Applications

• HPLC and UHPLC mobile phase preparation and column equilibration
• LC-MS and ICP-MS solvent blanks and calibration standards
• Cell culture media formulation and reagent dilution
• PCR, qRT-PCR, and next-generation sequencing (NGS) workflows
• Atomic absorption spectroscopy (AAS) and inductively coupled plasma (ICP) sample digestion
• Electrophysiology buffer preparation and patch-clamp solutions
• Pharmaceutical stability testing and dissolution media preparation per USP & Ph. Eur.
• Trace metal analysis requiring sub-ppt contamination thresholds

FAQ

What feed water quality is required for optimal Eco-Q performance?
Municipal tap water with TDS ≤ 200 ppm, temperature 5–45 °C, and inlet pressure 1.0–4.0 bar is recommended. For higher TDS sources, external softening or pretreatment is advised to prevent premature scaling.
How often must consumables be replaced under typical lab usage?
Pre-filters: 6–12 months; RO membrane: 2–3 years (with proper flushing); UV lamp: 12 months; DI cartridge: 6–18 months depending on feed water load and usage volume.
Is the system compatible with external storage tanks or distribution loops?
Yes — the Eco-Q can be configured for direct loop feed via optional recirculation pump and loop sanitization module (UV + heat), supporting centralized ultrapure water distribution in multi-user facilities.
Does the Eco-Q support remote monitoring or network connectivity?
Standard configuration includes local display and USB export only. Ethernet or Wi-Fi modules are available as factory-installed options for integration into building management systems (BMS) or centralized water quality dashboards.
What validation documentation is provided with the system?
Each unit ships with Factory Acceptance Test (FAT) report, Certificate of Conformance, material certifications for all wetted parts, and a complete consumables compatibility matrix aligned with ISO 9001 and ISO 13485 manufacturing practices.
