Overview
The Hitachi F-Series Fluorescence Spectrophotometer Replacement Xenon Lamp (Model 250-1600) is a precision-engineered, ozone-free short-arc xenon lamp designed exclusively for integration into Hitachi’s high-performance benchtop fluorescence spectrophotometers. Operating at a nominal power of 150 W, this lamp delivers stable, broadband continuum emission across the deep UV to near-infrared range (approximately 190–1100 nm), enabling high-sensitivity excitation in both steady-state and time-resolved fluorescence measurements. Its internal illumination configuration ensures optimal optical coupling with the instrument’s monochromator input optics, minimizing stray light and preserving spectral purity. The lamp is manufactured under Hitachi’s original specifications in Japan and conforms to stringent photometric stability and arc-centering tolerances required for reproducible quantum yield determination, lifetime decay analysis, and multi-wavelength excitation scanning.
Key Features
- Genuine Hitachi OEM component—manufactured in Japan to original equipment specifications and calibrated for spectral radiance consistency
- Ozone-free quartz envelope composition eliminates hazardous ozone generation during operation, supporting safe laboratory deployment without dedicated exhaust ducting
- Rated lifetime of ≥1,000 hours under standard operating conditions (defined as continuous DC-powered operation at rated current, ambient temperature ≤25 °C, and proper cooling airflow)
- Precise arc geometry and electrode alignment ensure repeatable beam profile and minimal divergence, critical for maintaining excitation efficiency across successive lamp replacements
- Designed for plug-and-play compatibility with Hitachi F-2700, F-4500, F-4600, and F-7000 spectrophotometers—no firmware update or recalibration required upon installation
- Robust mechanical housing with standardized base (e.g., U-shaped or linear-pin configuration per Hitachi mechanical drawings) ensures secure mounting and thermal dissipation
Sample Compatibility & Compliance
This xenon lamp is intended solely for use within Hitachi fluorescence spectrophotometers and is not interchangeable with lamps from other manufacturers or instrument platforms. It complies with IEC 62471:2006 (Photobiological Safety of Lamps and Lamp Systems) for UV radiation hazard classification (Risk Group 2). While the lamp itself is not subject to FDA 21 CFR Part 11, its use in regulated environments (e.g., pharmaceutical QC labs) supports compliance when operated within validated instrument workflows adhering to ASTM E275, USP , and ISO/IEC 17025 requirements for photometric traceability. No mercury or lead content—fully RoHS 2011/65/EU compliant.
Software & Data Management
No embedded firmware or software interface is associated with the lamp; it functions as a passive optical source governed entirely by the host spectrophotometer’s power supply and control architecture. Instrument software—including Hitachi FL Solutions and optional GLP-compliant data acquisition modules—automatically logs lamp usage time (if enabled via system counter) and may trigger maintenance alerts based on cumulative operational hours. Audit trails generated during lamp replacement events are retained within the instrument’s internal memory or exported CSV reports, supporting GMP documentation practices where lamp history is part of equipment qualification (IQ/OQ/PQ).
Applications
- Quantitative fluorescence assays in biochemistry and molecular biology (e.g., protein folding studies, ligand-binding kinetics)
- Environmental analysis of polycyclic aromatic hydrocarbons (PAHs) and dissolved organic matter using excitation-emission matrix (EEM) spectroscopy
- Materials science characterization of quantum dots, perovskite nanocrystals, and organic semiconductors
- Pharmaceutical stability testing per ICH Q1B guidelines, including photostability assessment under controlled irradiance conditions
- High-resolution synchronous scanning for complex mixture resolution in food authenticity verification and forensic chemistry
FAQ
Is this lamp compatible with Hitachi F-7100 or newer models?
No—Model 250-1600 is certified only for F-2700, F-4500, F-4600, and F-7000. The F-7100 uses a different lamp assembly (Part No. 250-1700) with revised thermal management and electrical interface.
Does the lamp require special alignment tools during installation?
Yes—Hitachi recommends using the official lamp alignment jig (Accessory Kit No. 250-1610) to verify arc position relative to the monochromator entrance slit; misalignment degrades signal-to-noise ratio and shortens effective lifetime.
Can this lamp be operated outside its specified current range to extend life?
Operating below rated current reduces radiant output and may cause unstable arc ignition or cathode sputtering—both degrade long-term performance. Always follow Hitachi’s published power supply settings.
Is there a certificate of conformance included?
Each unit ships with a Japanese-manufactured COC bearing Hitachi’s factory serial number, production lot code, and photometric test summary (intensity @ 365 nm, arc center deviation ±0.1 mm).
What is the recommended storage condition?
Store unopened in original packaging at 10–25 °C, 30–60% RH, away from direct UV exposure and vibration sources; avoid temperature cycling to prevent quartz envelope stress.
