Overview
The ASM UV Lamp 254 nm (Model CYRES00UV) is a precision-engineered ultraviolet irradiation source designed for laboratory-scale photolysis, nucleic acid visualization, crosslinking validation, and low-pressure UV disinfection monitoring in ultra-pure water systems. Operating at a narrow spectral peak of 254 nm—corresponding to the maximum DNA/RNA absorption wavelength—the lamp utilizes low-pressure mercury vapor discharge technology to deliver stable, monochromatic UVC output. It is not a standalone purification system but functions as a critical optical module integrated into ultra-pure water (UPW) distribution loops, TOC reduction units, or benchtop UV reactors where germicidal efficacy and photolytic degradation of trace organics (e.g., ozone residuals, chloramines, or low-molecular-weight organics) must be validated or controlled. Its design prioritizes thermal stability, spectral consistency, and long-term radiometric reproducibility under continuous or pulsed operation.
Key Features
- Monochromatic 254 nm emission with ±2 nm spectral bandwidth, optimized for germicidal action and nucleic acid detection
- Quartz sleeve housing with high UVC transmittance (>90% at 254 nm) and resistance to hydrolysis and thermal shock
- Integrated ballast-compatible electrical interface supporting standard 100–240 V AC, 50/60 Hz input
- Rated service life of ≥8,000 hours at rated power, with output decay <15% over lifetime (per IEC 62471 photobiological safety testing)
- Compact cylindrical form factor (Ø25 mm × 360 mm typical) enabling drop-in replacement in OEM UPW systems and custom UV reactors
- Compliance with RoHS 2011/65/EU and REACH Annex XVII for hazardous substance restrictions
Sample Compatibility & Compliance
The CYRES00UV lamp is intended for use in controlled laboratory environments where UV exposure is applied to aqueous streams, gaseous headspaces, or surface-irradiated biological samples. It is compatible with deionized water, Type I ultrapure water (resistivity ≥18.2 MΩ·cm), and buffered saline solutions—but not recommended for direct immersion in aggressive solvents or high-salinity brines without protective quartz encapsulation. The device meets IEC 61000-6-3 (EMC emissions) and IEC 61000-6-2 (immunity) standards. When deployed in pharmaceutical or biotech water systems, it supports alignment with USP “Water for Pharmaceutical Purposes” and ISO 14644-1 Class 5 cleanroom-grade UPW distribution requirements—provided system-level validation (e.g., UV dose mapping per ASTM E2493-22) is performed by the end user.
Software & Data Management
As a passive optical component, the CYRES00UV does not incorporate embedded firmware, microcontrollers, or digital interfaces. Radiometric performance verification requires external instrumentation—including NIST-traceable UVC radiometers (e.g., ILT950UV or Sper Scientific 850022) calibrated at 254 nm—and periodic intensity logging per facility SOPs. For integration into automated UPW systems, analog 4–20 mA UV intensity feedback signals may be derived via optional external sensor modules. All operational records—including lamp runtime, replacement dates, and radiometric calibration certificates—must be maintained in accordance with GLP and GMP documentation practices (21 CFR Part 11 compliant electronic records if digitized).
Applications
- Germicidal validation in point-of-use ultra-pure water loops for semiconductor wafer rinsing and biopharmaceutical buffer preparation
- Photolytic breakdown of residual ozone and total organic carbon (TOC) in UPW polishing stages
- UV crosslinking optimization for nucleic acid immobilization on nylon membranes (e.g., Southern/Northern blotting)
- Calibration reference source for spectrophotometric DNA quantification workflows (A260/A280 ratio verification)
- In-line UV dose monitoring in research-scale photochemical reactors for advanced oxidation process (AOP) development
FAQ
Is the CYRES00UV lamp suitable for direct sterilization of surfaces or air?
No—it is engineered for liquid-phase irradiation in closed-loop water systems or controlled optical setups, not open-air or non-contained surface disinfection.
Does Deepflow provide NIST-traceable calibration certificates with each unit?
Calibration certificates are available upon request and subject to third-party accreditation; they are not included by default but may be ordered separately with lead-time notification.
Can this lamp be operated continuously for 24/7 UPW circulation systems?
Yes—its thermal management and electrode design support uninterrupted operation; however, scheduled intensity verification every 500–1,000 hours is recommended per ISO 15195:2018 guidance.
What is the recommended replacement interval under typical lab usage?
Based on cumulative operating hours and measured irradiance decay, replacement is advised at 8,000 hours or when output falls below 85% of initial specification—whichever occurs first.
Is the lamp compatible with existing UPW systems from ELGA, Veolia, or Sartorius?
Mechanical and electrical compatibility depends on socket type, cooling configuration, and control interface; dimensional drawings and I/O schematics are available under NDA for OEM integration assessment.
