Overview
The Deepflow CYXUVLPL1 is a high-intensity, large-format ultraviolet lamp engineered for germicidal irradiation at the standard disinfection wavelength of 254 nm. This wavelength corresponds to the peak DNA/RNA absorption band of microorganisms, enabling efficient inactivation of bacteria, viruses, yeasts, and spores through thymine dimer formation. Designed specifically for integration into ultra-pure water (UPW) systems and laboratory purification workflows, the CYXUVLPL1 serves as a critical non-chemical barrier in multi-stage water treatment trains—typically positioned downstream of reverse osmosis and upstream of final 0.22 µm filtration. Its robust quartz sleeve construction ensures optimal UV transmission (>90% at 254 nm) and resistance to thermal shock and chemical exposure common in UPW recirculation loops.
Key Features
- Fixed-wavelength output at 254 nm ± 2 nm, generated by low-pressure mercury vapor discharge with high spectral purity
- Large active irradiation area optimized for high-flow UPW applications (compatible with flow rates up to 2–5 L/min depending on chamber geometry)
- Quartz envelope with high UV transmittance (≥90%) and integrated ozone-free design to prevent unintended ozonation of water streams
- Integrated thermal management system ensuring stable output over extended operational cycles (rated for continuous duty >8,000 hours)
- Modular mounting interface compatible with standard sanitary fittings (e.g., 1/2″–1″ Tri-Clamp or ISO-KF) for seamless integration into existing UPW distribution panels
- Electrical safety compliance with IEC 61000-6-3 (EMC) and IEC 61000-6-2 (immunity); CE-marked per Directive 2014/30/EU
Sample Compatibility & Compliance
The CYXUVLPL1 is validated for use in pharmaceutical-grade ultra-pure water systems conforming to USP , EP 2.2.43, and JP 2.05 standards for water quality and microbial control. It supports Good Manufacturing Practice (GMP) and Good Laboratory Practice (GLP) environments where documented validation of UV dose delivery (measured in mJ/cm²) is required. The lamp’s performance is traceable to NIST-traceable radiometric calibration protocols. When installed in validated UPW loops, it contributes to meeting FDA 21 CFR Part 11 requirements for electronic records integrity when paired with compliant monitoring controllers that log real-time UV intensity, lamp runtime, and system flow rate.
Software & Data Management
While the CYXUVLPL1 operates as a standalone hardware module, its integration into modern UPW systems typically occurs via analog 4–20 mA or digital Modbus RTU interfaces. Compatible supervisory controllers provide automated dose calculation (UV fluence = intensity × residence time), lamp aging compensation, and event-triggered alerts for intensity decay below 70% nominal output. Audit trails—including lamp ignition count, cumulative operating hours, and maintenance timestamps—are stored locally and exportable in CSV format for regulatory review. Firmware updates and configuration are performed using vendor-supplied PC utilities compliant with ISO/IEC 17025 software validation guidelines.
Applications
- Germicidal treatment in point-of-use (POU) and point-of-entry (POE) ultra-pure water systems for analytical laboratories and QC testing suites
- Final polishing step in semiconductor-grade water purification lines (ASTM D5127 Class E1/E2)
- Microbial load reduction in buffer preparation systems for biopharmaceutical manufacturing
- Validation support for ISO 14644-1 cleanroom water supply networks requiring ≤1 CFU/100 mL microbiological specifications
- Research applications involving nucleic acid workstations where surface decontamination and ambient air sterilization are required
FAQ
What is the typical UV dose delivered by the CYXUVLPL1 in a standard UPW loop?
Dose depends on flow rate, chamber path length, and sensor-calibrated intensity; typical validated doses range from 30–100 mJ/cm² under nominal conditions.
Is the lamp compatible with hydrogen peroxide vapor (HPV) decontamination cycles?
Yes—the quartz housing and stainless-steel end caps are resistant to HPV exposure; however, lamp operation must be suspended during decon cycles per IEC 62366 risk management guidance.
Does the CYXUVLPL1 require annual recalibration?
Radiometric output drift is monitored via built-in UV sensors; full recalibration against a NIST-traceable reference source is recommended every 12 months or after 8,000 hours of operation.
Can this lamp be used for TOC reduction?
No—254 nm UV alone does not significantly degrade total organic carbon; for TOC abatement, a 185 nm vacuum UV source or advanced oxidation process (AOP) configuration is required.
What documentation is provided for GMP validation?
Deepflow supplies Factory Acceptance Test (FAT) reports, IQ/OQ templates, material certifications (EN 10204 3.1), and lamp spectral emission profiles certified per ISO/IEC 17025.
