Overview
The Deepflow CYTANKPE60 is a 60-liter polyethylene (PE) ultra-pure water storage tank engineered for integration into laboratory-grade ultrapure water (UPW) distribution systems. Designed to maintain the integrity of Type I ultrapure water (resistivity ≥18.2 MΩ·cm at 25 °C, total organic carbon <5 ppb, bacterial count <0.1 CFU/mL), this tank serves as a critical buffer and holding vessel downstream of UPW generation units—such as reverse osmosis/deionization (RO/DI) or electrodeionization (EDI) systems—and upstream of point-of-use dispensers, analytical instruments (e.g., HPLC, ICP-MS, LC-MS), and cell culture workstations. Its seamless, sanitary-grade PE construction minimizes leachables and particulate shedding, while the enclosed, vent-filtered design (0.22 µm hydrophobic PTFE membrane) prevents atmospheric contamination without compromising pressure equilibrium.
Key Features
- 60-liter capacity with calibrated volume markings and integrated level sensor interface (4–20 mA or 0–5 V output compatible)
- Food-grade linear low-density polyethylene (LLDPE) housing—certified to USP Class VI and ISO 10993-5 for biocompatibility and extractables control
- Sanitary, crevice-free interior geometry with 30° conical bottom for complete drainage and reduced dead-leg volume
- Standard 1/2″–3/4″ BSP or NPT threaded ports (inlet, outlet, overflow, drain, vent) with EPDM or FKM O-rings for chemical resistance
- Integrated 0.22 µm hydrophobic PTFE vent filter (ISO 13408-1 compliant) with dual-stage moisture trap and automatic condensate purge function
- Optional accessories: UV-C germicidal lamp (254 nm, 12 W), temperature probe (Pt100), conductivity/resistivity sensor port, and stainless-steel support frame (316L)
Sample Compatibility & Compliance
The CYTANKPE60 is validated for continuous storage of ASTM Type I, ISO 3696 Grade 1, and CLSI EP28-A3c-compliant ultrapure water. It meets material compatibility requirements for USP Total Organic Carbon and Conductivity testing protocols. The tank’s construction and surface finish comply with Good Manufacturing Practice (GMP) Annex 1 principles for water system qualification, supporting IQ/OQ/PQ documentation packages. All wetted components are non-metallic and pass USP plastic identification and extractables testing per ICH Q5C guidelines. It is suitable for GLP-regulated environments where audit trails for water quality parameters (temperature, resistivity, TOC, microbial load) are required.
Software & Data Management
While the CYTANKPE60 is a passive storage unit, its modular porting supports seamless integration with centralized water system monitoring platforms—including Deepflow’s AquaTrack™ SCADA-compatible controllers and third-party LIMS or MES systems via Modbus RTU/TCP or OPC UA. Optional analog/digital I/O modules enable real-time logging of tank level, inlet/outlet conductivity, and UV lamp status. All data points adhere to FDA 21 CFR Part 11 requirements when paired with validated software: electronic signatures, user access controls, immutable audit trails, and configurable alarm thresholds (e.g., low-level shutdown, high-conductivity bypass). Calibration records and maintenance logs are exportable in CSV or PDF format for regulatory submissions.
Applications
- Buffer reservoir in multi-point ultrapure water distribution loops serving analytical labs, QC/QA facilities, and R&D cleanrooms
- Intermediate storage between primary purification and secondary polishing stages (e.g., before 0.1 µm final filtration or UV oxidation)
- Stabilization volume for pressure-sensitive instruments requiring constant flow and minimal pulsation (e.g., trace-element analyzers, semiconductor wafer rinsing stations)
- Emergency reserve capacity during scheduled maintenance of upstream purification modules
- Supporting ISO 14644-1 Class 5–7 cleanroom water supply networks with documented microbial control intervals
FAQ
Is the CYTANKPE60 suitable for pharmaceutical-grade WFI (Water for Injection) applications?
No—it is designed for ultrapure water (UPW), not sterilized WFI. WFI requires validated steam sterilization capability, 316L stainless steel construction, and compliance with USP , which this PE tank does not fulfill.
Can the tank be autoclaved or steam-sanitized?
No. Polyethylene has a maximum continuous service temperature of 60 °C; exposure to saturated steam (>100 °C) will cause deformation and compromise structural integrity.
What is the recommended cleaning and sanitization protocol?
Rinse with ≥18.2 MΩ·cm water, followed by circulation of 0.5% hydrogen peroxide (H₂O₂) at ambient temperature for 2 hours, then thorough rinse until peroxide residuals are undetectable (<10 ppb).
Does Deepflow provide validation support for IQ/OQ?
Yes—protocol templates, test scripts, and witnessed execution services are available under separate GxP-compliant service agreements.
Is the vent filter replaceable, and what is its typical service life?
Yes—the 0.22 µm PTFE vent filter is field-replaceable and rated for ≥12 months under continuous operation in controlled indoor environments with ≤60% RH.
