Overview
The HHitech Pilot-S Standard Ultra Pure Water System is a laboratory-grade, integrated water purification platform engineered for consistent production of Type I ultrapure water (ASTM D1193-20, ISO 3696:1987, USP , CLSI EP22-A, and GB/T 33087-2016 compliant) from municipal tap feed water. Utilizing a multi-stage purification architecture—comprising pre-filtration (PP + activated carbon), dual-stage reverse osmosis (RO), post-RO carbon polishing, electrodeionization (EDI)-compatible ion exchange, and terminal 0.2 µm PES membrane filtration—the system delivers water with resistivity up to 18.2 MΩ·cm at 25 °C, TOC <3 ppb, endotoxin <0.001 EU/mL, and bacterial count <0.001 CFU/mL. Designed for mid-to-high throughput labs, the Pilot-S achieves flow rates of 45–125 L/h (model-dependent), with built-in 15 L pressurized storage tanks enabling uninterrupted supply during peak demand or maintenance cycles.
Key Features
- Microprocessor-controlled operation with backlit LCD display (240 × 128 resolution, 106 × 57 mm active area) supporting animated real-time process visualization
- Triple-point online water quality monitoring: feed water, RO permeate, and final ultrapure water—with configurable alarm thresholds for conductivity, resistivity, TOC, and pressure
- Automated RO membrane anti-scaling flush cycle triggered by runtime or pressure differential, extending membrane service life beyond 24 months under typical municipal feed conditions (TDS <200 ppm)
- Dual-level password protection (factory + user) for system configuration, parameter adjustment, and calibration access—fully compliant with GLP audit requirements
- Consumable lifetime tracking with predictive replacement alerts: prefilter, RO membrane, UV lamp (185/254 nm dual-wavelength), ultrafiltration (MWCO 5000 Da), and mixed-bed DI resin cartridges
- Programmable timed and quality-triggered dispensing (1–99 min; resistivity setpoint 0.1–18.2 MΩ·cm), supporting standardized sample preparation protocols
- NSF-certified fluid path components—including tubing, quick-connect fittings, and sanitary valves—to ensure material compatibility and leachables control
- Stainless steel powder-coated chassis with adjustable leveling feet; footprint optimized for floor-standing deployment in ISO Class 7 cleanrooms or QC laboratories
Sample Compatibility & Compliance
The Pilot-S Standard meets stringent regulatory and methodological requirements for critical applications including HPLC mobile phase preparation, ICP-MS calibration standard dilution, cell culture media formulation, molecular biology assays (PCR, qRT-PCR, NGS library prep), and pharmaceutical stability testing. Its output complies with USP “Water for Pharmaceutical Purposes”, FDA 21 CFR Part 11 data integrity provisions (when equipped with RS232/USB logging), ISO/IEC 17025 traceability standards, and GLP documentation workflows. All wetted materials—including Dow Filmtec™ RO membranes, nuclear-grade mixed-bed resins, and PES-based 0.2 µm terminal filters—are certified free of RNase/DNase contamination (<1 pg/mL and <5 pg/mL respectively) and extractables per USP .
Software & Data Management
Equipped with optional RS232 or USB interface, the Pilot-S logs timestamped conductivity, temperature, pressure, and alarm events continuously for ≥12 months. Data export is compatible with CSV and Excel formats for integration into LIMS or electronic lab notebooks (ELN). Audit trail functionality records all operator actions—including login/logout, parameter changes, and consumable resets—with immutable timestamps and user ID attribution. Firmware supports remote diagnostics via serial command protocol, enabling preventive maintenance scheduling without physical access.
Applications
- Trace metal analysis (ICP-OES, ICP-MS) requiring sub-ppt contaminant control
- High-sensitivity immunoassays and ELISA where endotoxin-induced false positives must be eliminated
- Single-cell RNA sequencing library construction demanding RNase-free water
- Pharmaceutical QC release testing per USP monographs and EP 2.2.44
- Calibration of conductivity meters and reference electrodes in metrology labs
- Centralized distribution systems when retrofitted with external recirculation pumps and loop sanitization modules
FAQ
What feed water specifications are required for optimal RO 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 or hardness, external softening or antiscalant dosing is advised.
Is the system validated for GMP environments?
Yes—the Pilot-S supports IQ/OQ documentation packages, conforms to Annex 11 (EU GMP) electronic record requirements when configured with data logging, and provides full traceability for consumables and calibration events.
Can the system be integrated into an existing lab water network?
Absolutely. The chassis includes internal mounting space for recirculation pumps and UV loop sterilizers; outlet ports support 1/4″ compression or sanitary tri-clamp connections.
How often must the ultrafiltration cartridge be replaced?
Under typical usage (≤1000 L/day), the MWCO 5000 Da UF module lasts 6–12 months; lifetime is dynamically calculated based on cumulative flow and pressure drop across the membrane.
Does the system meet NSF/ANSI Standard 58 for RO systems?
While not certified as a standalone drinking water device, all RO components—including Dow Filmtec™ membranes and NSF-listed housings—meet NSF/ANSI 58 material safety requirements for indirect food contact.
