ULUPURE UPHD Mobile Dispensing Handle for Ultra-Pure Water Systems

Overview

The ULUPURE UPHD Mobile Dispensing Handle is a precision-engineered terminal interface designed for ultra-pure water (UPW) distribution in modern analytical and life science laboratories. It operates as either a standalone accessory or an integrated component of ULUPURE’s pressure-fed pure water storage tanks and centralized UPW distribution systems (e.g., ULPHW I–IV, UPHN/UPRN, and UPL series). Engineered for seamless integration with Type I ultrapure water systems compliant with ASTM D1193-20, ISO 3696:1987, and CLSI EP21-A guidelines, the UPHD delivers consistent 18.24 MΩ·cm resistivity water at point-of-use—subject to upstream system performance and real-time monitoring configuration. Its core function is to decouple dispensing flexibility from fixed-position outlets, enabling ergonomic, contamination-controlled delivery across diverse vessel geometries without compromising microbial or endotoxin integrity.

Key Features

• 360° Rotational Freedom & Height Adjustment: Precision-machined pivot joint and telescoping vertical column allow full rotational range and continuous height adjustment (550 mm max extension), accommodating volumetric flasks, centrifuge tubes, culture bottles, and tall glassware without repositioning the base unit.
• Detachable Modular Design: The handle detaches cleanly from its mounting arm via quick-lock coupling—enabling handheld operation while maintaining full functional parity with fixed installations.
• 3.5-inch TFT Touchscreen Interface: Intuitive graphical user interface supports multilingual configuration (English default), real-time parameter visualization, and menu-driven setup without external software dependencies.
• Terminal Filtration Integrity: Standard-integrated 0.22 µm hydrophilic PES membrane filter certified for bacterial retention (≥log 7 reduction), endotoxin removal (<0.001 EU/mL), and nuclease-free operation (DNase/RNase < 0.01 pg/µL).
• Multi-Mode Dispensing Logic: Supports three distinct operational modes: (1) Instant Flow (press-and-hold activation), (2) Programmable Volumetric Dispensing (10–5000 mL, ±1% repeatability), and (3) Predefined Quick-Volume Selection (100/200/300/500/1000/2000 mL with visual LED confirmation).
• Quality-Gated Dispensing: “Quality-Triggered Dispense” mode allows setting resistivity thresholds (0–18.24 MΩ·cm); water flow automatically halts if downstream conductivity exceeds the configured limit—ensuring only compliant water is delivered.

Sample Compatibility & Compliance

The UPHD is compatible with all ULUPURE pressure-driven ultrapure water reservoirs and central distribution networks operating within 0.1–0.3 MPa supply pressure ranges. Its stainless-steel and medical-grade PEEK wetted path materials meet USP Class VI biocompatibility requirements. When paired with optional inline TOC and resistivity sensors (ULUPURE Model UPM-SR2), the system supports GLP/GMP-compliant audit trails per FDA 21 CFR Part 11 when connected to ULUPURE’s host controller firmware v3.2+. All filtration components carry valid ISO 13485-certified manufacturing documentation and are traceable via batch-specific CoA reports.

Software & Data Management

No proprietary software installation is required—the UPHD operates autonomously via embedded firmware. All dispensing events—including volume dispensed, timestamp, water quality parameters (if sensors installed), and alarm triggers—are logged internally in non-volatile memory. Data export is performed via standard USB-A port to generate ASCII-formatted .TXT files compatible with LIMS, ELN, or Excel-based QA review workflows. Optional thermal printer module (ULUPURE PRT-T1) enables real-time hardcopy generation of each dispense record, satisfying internal SOPs requiring physical signature verification.

Applications

• Cell culture media preparation requiring endotoxin-free water
• HPLC mobile phase preparation and LC-MS solvent dilution
• Molecular biology applications including PCR, qRT-PCR, and NGS library prep
• Calibration standard preparation for ICP-MS and AAS instrumentation
• Pharmaceutical QC testing under USP Water for Injection (WFI) handling protocols
• High-throughput screening workflows where spatial flexibility reduces cross-contamination risk

FAQ

Is the UPHD compatible with non-ULUPURE water purification systems?
Yes—provided the source system delivers stable pressure (0.1–0.3 MPa) and meets Type I ultrapure water specifications per ASTM D1193-20; however, full alarm integration and data logging require ULUPURE host controller firmware.
Can the terminal filter be replaced by the user?
Yes—the 0.22 µm PES cartridge features tool-free twist-lock replacement with validated seal integrity; replacement interval is determined by total dispensed volume and upstream pretreatment condition.
Does the UPHD support RS-232 or Ethernet connectivity?
No—communication is limited to USB data export and local touchscreen control; networked telemetry requires integration via ULUPURE’s central system controller (ULPHW-CPU v4.0+).
What is the maximum allowable ambient temperature for continuous operation?
40°C ambient, with relative humidity ≤80% non-condensing; extended exposure above 35°C may affect touchscreen responsiveness and filter lifespan.
Is calibration of the flow sensor required?
No—volumetric accuracy is factory-validated using gravimetric NIST-traceable methodology; periodic verification against calibrated balance is recommended every 6 months per ISO/IEC 17025 internal audit requirements.
