TimePower TP301/TP302 Ultra Pure Water System

Overview

The TimePower TP301/TP302 Ultra Pure Water System is an integrated, dual-stage laboratory water purification platform engineered for consistent delivery of Type I ultrapure water (ASTM D1193-20) and Type III purified water (ASTM D1193-20) from municipal or pretreated feed water sources. It employs a multi-step purification architecture comprising pre-filtration (sediment + activated carbon), reverse osmosis (RO), electrodeionization (EDI), and final polishing via dual-wavelength UV oxidation (185 nm + 254 nm) coupled with a 0.1 µm hydrophilic membrane filter and ultra-low endotoxin (<0.001 EU/mL) final cartridge. This configuration ensures removal of ions, organics, particles, microorganisms, and pyrogens to meet stringent requirements for critical applications in analytical chemistry, molecular biology, cell culture, HPLC mobile phase preparation, and trace elemental analysis.

Key Features

• Real-time resistivity monitoring (0–18.25 MΩ·cm) with temperature compensation (25 °C), displayed on a high-resolution color LCD touchscreen interface
• Intelligent IC microcontroller with programmable self-diagnostic startup sequence and automated system health checks
• Configurable timed recirculation loop (1–24 h intervals) to maintain TOC < 3 ppb and microbial levels < 0.001 EU/mL during standby
• Dual-mode operation: simultaneous or independent production of Type III purified water (for glassware rinsing, buffer preparation) and Type I ultrapure water (for sensitive assays)
• US-sourced DC-powered ultra-pure water delivery pump ensuring low pulsation, zero metal leaching, and flow rates up to 2.0 L/min at point-of-use
• Quantitative dispensing mode with preset volume selection (10 mL–9999 mL), automatic stop, and audit-trail logging (optional GLP-compliant software module)
• Modular consumables design with RFID-tagged cartridges for usage tracking, replacement alerts, and maintenance history archiving

Sample Compatibility & Compliance

The TP301/TP302 is validated for compatibility with feed water meeting municipal drinking water standards (EPA 600/R-97/004, GB 5749-2022). Its output meets or exceeds specifications defined in ASTM D1193-20 (Type I), ISO 3696:1987 (Grade 1), CLSI EP22-A2 (water for clinical laboratories), and USP “Water for Pharmaceutical Purposes”. The system supports GMP/GLP environments through optional 21 CFR Part 11-compliant software add-ons enabling electronic signatures, user access control, and immutable audit trails. Endotoxin and bioburden performance are verified per ISO 14644-1 Class 5 cleanroom-compatible protocols and validated against pharmacopeial bacterial endotoxin test (BET) requirements.

Software & Data Management

The embedded firmware supports USB data export (CSV format) of all operational parameters—including date/time stamps, resistivity trends, TOC logs, UV lamp intensity, filter life counters, and alarm events. Optional PC-based TimePower AquaControl™ software enables remote monitoring, historical trend analysis, predictive maintenance scheduling, and report generation compliant with ISO/IEC 17025 documentation requirements. All data storage adheres to ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) for regulatory submissions.

Applications

• HPLC, UHPLC, and LC-MS mobile phase and blank preparation
• ICP-MS, ICP-OES, and AAS standard dilution and instrument rinse solutions
• Cell culture media formulation and sterile filtration support
• PCR, qRT-PCR, NGS library preparation, and electrophoresis buffer systems
• Pharmaceutical stability testing, dissolution media, and excipient diluent preparation
• Calibration of conductivity meters, TOC analyzers, and particle counters
• Microelectronics wafer cleaning, photolithography rinse steps, and thin-film deposition processes

FAQ

What feed water quality is required for optimal TP301/TP302 performance?

Municipal tap water with total dissolved solids (TDS) ≤ 500 ppm, chlorine ≤ 3 ppm, and turbidity ≤ 1 NTU is recommended. Pre-treatment with a dedicated sediment/carbon unit is advised if feed water exceeds these limits.
Can the system be integrated into a centralized lab water network?

Yes—TP301/TP302 supports looped distribution via stainless steel 316L piping with recirculation pumps; optional pressure booster and reservoir modules are available for multi-point installations.
How often must consumables be replaced under typical lab usage?

Pre-filters: every 6 months; RO membrane: 2–3 years; EDI stack: 3–5 years; UV lamps: annually; final 0.1 µm/UF cartridge: 6–12 months depending on daily volume and microbial load.
Does the system comply with FDA 21 CFR Part 11 for electronic records?

Out-of-the-box compliance is not included, but the optional AquaControl™ software package provides full Part 11 functionality including role-based access, electronic signatures, and audit trail encryption.
Is validation documentation (IQ/OQ/PQ) provided?

Factory-issued IQ/OQ protocols are supplied with each unit; PQ templates and on-site qualification support are available as a professional services option.
