Overview
The EX UV Lamp 254 nm (Model CYXUVLP01) is a precision ultraviolet irradiation source engineered for laboratory-scale photolysis, nucleic acid visualization, crosslinking validation, and low-pressure germicidal applications. Operating at a narrow spectral peak of 254 nm—corresponding to the maximum DNA/RNA absorption band and optimal for mercury-vapor line emission—the lamp delivers stable, collimated UVC output suitable for integration into purification workflows, including ultra-pure water systems and downstream sterilization modules. Unlike broadband UV sources, this low-pressure mercury lamp provides high photon flux density at the biologically critical 254 nm wavelength, enabling reproducible inactivation of microorganisms (e.g., bacteria, viruses, spores) and controlled photochemical degradation of organic contaminants such as ozone precursors or residual chlorine byproducts. Its design complies with IEC 62471 (Photobiological Safety of Lamps) and supports alignment with ISO 15195:2018 (requirements for UV-based water treatment validation).
Key Features
- Stable 254 nm monochromatic output from low-pressure mercury vapor discharge, with spectral half-width <2 nm
- Integrated quartz sleeve housing resistant to UVC-induced solarization, ensuring >95% transmittance retention after 5,000 hours of operation
- Thermally stabilized cold-cathode design for consistent irradiance output across ambient temperatures from 15–35 °C
- Compact form factor (L × W × H: 320 × 45 × 45 mm) optimized for OEM integration into ultra-pure water distribution loops and laminar flow hoods
- CE-marked power supply with overvoltage/overcurrent protection and automatic thermal cutoff at >70 °C
- Compliance with RoHS Directive 2011/65/EU and REACH Annex XVII restrictions on hazardous substances
Sample Compatibility & Compliance
The CYXUVLP01 is compatible with standard 1/4-inch and 3/8-inch stainless-steel or PTFE-lined UV reactor manifolds used in Type I ultra-pure water systems (per ISO 3696 and ASTM D1193). It supports continuous-duty operation under Class A cleanroom conditions (ISO 14644-1) when installed with appropriate shielding and interlocked access panels. The lamp meets EN 60335-1 safety requirements for household and similar electrical appliances and is validated for use in GLP-compliant laboratories where traceability of UV dose (mJ/cm²) is required per USP and EP 2.2.59. Optional calibration certificates (NIST-traceable radiometric calibration at 254 nm) are available upon request.
Software & Data Management
While the CYXUVLP01 operates as a standalone hardware module, it is designed for seamless integration with third-party SCADA or PLC-based monitoring platforms via 4–20 mA analog output (UV intensity feedback) and dry-contact status signaling. When deployed within ultra-pure water systems, its operational parameters—including cumulative runtime, lamp-on cycles, and thermal event logs—can be recorded within the host system’s audit trail per FDA 21 CFR Part 11 requirements. Firmware-upgradable controllers (sold separately) support Modbus RTU/ASCII protocols for remote diagnostics and predictive maintenance scheduling based on lamp aging curves.
Applications
- Germicidal irradiation in point-of-use ultra-pure water polishing units (TOC reduction, microbial control)
- In-line UV dosimetry validation for pharmaceutical water-for-injection (WFI) distribution networks
- UV shadowing and ethidium bromide-free DNA gel documentation in molecular biology labs
- Photochemical oxidation of trace organics (e.g., formaldehyde, THMs) in purified water recirculation loops
- Validation of UV-transparent tubing materials (e.g., fluorinated ethylene propylene, FEP) per ASTM F2217
- Supporting ISO/IEC 17025-accredited testing of UV transmittance (UVT) in purified water samples
FAQ
What is the typical lifetime of the CYXUVLP01 lamp under continuous operation?
Rated average life is 8,000 hours at 25 °C ambient temperature with recommended duty cycling (max 12 h ON / 12 h OFF). Actual service life depends on thermal management and input voltage stability.
Is the lamp compatible with deionized water contact?
No direct immersion is permitted. It must be mounted behind a certified UV-transmitting quartz sleeve and integrated into a sealed reactor chamber compliant with IP65 ingress protection.
Does Deepflow provide radiometric calibration services?
Yes—NIST-traceable calibration reports (including spectral irradiance at 254 nm ±0.5 nm, measured with a calibrated thermopile sensor) are available as an optional add-on.
Can this lamp be used for UV-C disinfection of air?
Not recommended without engineering controls. This model is optimized for liquid-phase irradiation; airborne applications require dedicated upper-room or in-duct UVGI fixtures meeting UL 1598 and ASHRAE Standard 185.2.
What safety certifications does the unit hold?
CE (EMC Directive 2014/30/EU and LVD Directive 2014/35/EU), RoHS 2011/65/EU, and IEC 62471 Risk Group 3 (High Risk) classification with mandatory interlock interface requirement.
