Timepower TP301 / TP302 Series Laboratory Ultra-Pure Water Systems

Overview

The Timepower TP301 and TP302 Series Laboratory Ultra-Pure Water Systems are engineered for precision production of Type I ultra-pure water (UPW) and Type III pure water in research, quality control, and regulated analytical environments. These systems integrate multi-stage purification architecture—comprising pre-filtration, reverse osmosis (RO), mixed-bed ion exchange, and terminal ultrafiltration—to achieve stringent physicochemical and microbiological specifications. The core separation mechanism relies on size exclusion and charge rejection across semi-permeable RO membranes, followed by electrochemical deionization via high-capacity resin beds. Final polishing employs a 0.22 µm hydrophilic membrane filter to eliminate sub-micron particles and microorganisms. Designed for continuous operation under ISO/IEC 17025-aligned laboratory conditions, the TP301 accepts municipal tap water as feed; the TP302 is optimized for feed streams already pre-treated by RO or distillation—enabling higher throughput and extended consumables life in facilities with existing pretreatment infrastructure.

Key Features

• Real-time resistivity monitoring (0.01–18.25 MΩ·cm) with temperature compensation (25°C), displayed on a full-color LCD touchscreen interface with intuitive touch-key navigation.
• Automated daily RO membrane flush cycle and programmable ultra-pure water recirculation loop to maintain microbial and particulate integrity during standby periods.
• Dedicated low-pulsation DC booster pump (U.S.-sourced) ensures stable, vibration-free UPW delivery at flow rates up to 2.0 L/min—critical for HPLC mobile phase preparation and ICP-MS rinse protocols.
• Quantitative dispensing mode with adjustable volume presets (10 mL–5 L) and timed dispensing options, supporting GLP-compliant documentation workflows.
• Microprocessor-based IC control system with self-diagnostic routines, alarm logging, and service interval tracking for preventive maintenance scheduling.
• Modular consumables design: replaceable activated carbon cartridges, dual-stage RO modules, mixed-bed ion exchange columns, and sterile 0.22 µm terminal filters—all certified non-leaching and extractables-tested per USP and EP 2.2.42.

Sample Compatibility & Compliance

The TP301/TP302 systems produce water meeting or exceeding national and international standards for analytical-grade reagent water. RO output complies with GB/T 6682–2008 Grade III and ASTM D1193–22 Type III specifications (conductivity ≤50 µS/cm). Ultra-pure water output satisfies GB/T 6682–2008 Grade I and ASTM D1193–22 Type I requirements (resistivity ≥18.25 MΩ·cm @ 25°C, TOC ≤10 ppb, bacteria ≤1 CFU/mL). All performance claims are validated using traceable NIST-certified reference materials and calibrated conductivity/resistivity meters (±0.1% accuracy). System architecture supports audit readiness for ISO/IEC 17025, FDA 21 CFR Part 11 (when integrated with compliant LIMS), and GMP/GLP environments—particularly where water quality directly impacts assay validity (e.g., ELISA, qPCR, cell culture media preparation).

Software & Data Management

While the TP301/TP302 operate via embedded firmware without external PC dependency, the control unit logs timestamped operational data—including resistivity trends, pressure differentials across RO and UF stages, total volume dispensed, and alarm events—for up to 30 days. Data export is supported via USB interface (CSV format) for integration into lab-wide QA databases. Optional RS-485 Modbus RTU communication enables centralized monitoring in multi-unit installations. All user actions—including parameter adjustments, manual flush initiation, and service resets—are recorded with operator ID (if configured) and time stamp, fulfilling ALCOA+ data integrity principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Applications

These systems serve as primary water sources for high-sensitivity instrumentation requiring minimal background interference: HPLC and UHPLC mobile phase preparation; ICP-OES and ICP-MS sample dilution and instrument rinsing; molecular biology applications including PCR, electrophoresis, and next-generation sequencing library prep; trace metal analysis in environmental and clinical matrices; pharmaceutical stability testing per ICH Q5C; and calibration of conductivity and pH meters. Their consistent TOC and silica control also supports semiconductor wafer cleaning validation and photolithography solvent formulation in cleanroom-adjacent labs.

FAQ

What is the difference between TP301 and TP302 models?
The TP301 accepts municipal tap water as feed and integrates full pretreatment (sediment + carbon + softening); the TP302 requires pre-desalinated feed (RO permeate or distilled water) and focuses exclusively on UPW polishing—offering higher UPW yield and longer resin life in facilities with existing RO infrastructure.
Does the system support regulatory compliance for pharmaceutical QC labs?
Yes—its documented performance against GB/T 6682 and ASTM D1193, combined with audit-trail-capable event logging and material certifications for all wetted parts, supports qualification under GMP Annex 1 and USP Water for Pharmaceutical Purposes.
How often must consumables be replaced?
Carbon prefilter: every 6 months or 3,000 L; RO membrane: 2–3 years depending on feed water TDS and chlorine exposure; mixed-bed resin: 6–12 months based on UPW resistivity decay rate; terminal 0.22 µm filter: after 1,000 L or upon pressure differential >0.2 bar.
Can the system be connected to a central distribution loop?
Yes—equipped with a dedicated UPW recirculation port and compatible with stainless-steel 316L piping networks; optional UV irradiation module (254 nm, 40 mJ/cm²) is available for loop sanitization.
Is technical support available outside China?
Timepower provides remote diagnostics and multilingual documentation (English, German, Spanish); local authorized service partners are appointed in EU, North America, and APAC regions for on-site validation and preventive maintenance.
