Deuterium Lamp for Azzota UV-Vis Spectrophotometer Model S-122

Description

Product Overview

The Deuterium Lamp designed for Azzota UV‑Vis spectrophotometers combines precision engineering with durable materials to meet the rigorous demands of modern analytical laboratories. Constructed from high‑grade quartz glass, the lamp housing protects the delicate deuterium filament while allowing maximum transmission of ultraviolet radiation across the 160‑400 nm range. The S‑122 model features a sealed, low‑pressure environment that minimizes filament degradation, extending service life well beyond typical replacement intervals.</n

Key specifications include a nominal power consumption of 100 W, a luminous intensity of 1.2 mW/cm² at 254 nm, and a guaranteed operating temperature stability of ±0.5 °C. The lamp integrates seamlessly with Azzota’s proprietary UV‑Vis optical bench, aligning with the instrument’s built‑in calibration routines to ensure consistent baseline correction and absorbance accuracy. Its universal mounting interface adheres to the standard 1‑inch flange, eliminating the need for adapters or custom fittings.

Usage

Designed for a broad spectrum of laboratory applications, this deuterium lamp excels in quantitative analysis, quality control, and research environments where reliable UV illumination is critical. Whether you are measuring the absorbance of organic compounds, monitoring polymer degradation, or conducting microbiological sterility tests, the lamp provides a stable photon flux that reduces measurement variability and improves repeatability.

Installation is straightforward: remove the existing lamp module, align the new S‑122 unit with the instrument’s optical port, and secure it using the supplied torque‑controlled screw. No additional tools or calibration steps are required beyond the standard instrument warm‑up procedure. The lamp’s rapid warm‑up time—reaching full intensity within 30 seconds—allows analysts to resume work quickly, minimizing downtime during routine maintenance cycles.

FAQ

What is the expected lifespan of the Deuterium Lamp (model S‑122)?

The S‑122 lamp is rated for approximately 2,000 operating hours under normal laboratory conditions. With proper handling and routine cleaning of the optical path, many users achieve up to 2,500 hours before a performance drop is observed.

Can this lamp be used with spectrophotometers from other manufacturers?

While the lamp is optimized for Azzota instruments, its standard 1‑inch flange and universal UV output make it compatible with most UV‑Vis spectrophotometers that accept deuterium sources, provided the mounting geometry aligns with the instrument’s optical port.

How do I know when the lamp needs replacement?

Typical indicators include a gradual decline in UV intensity, increased baseline noise, or a failure to reach the specified 254 nm output during calibration checks. The instrument’s built‑in diagnostics will flag a lamp performance issue, prompting a replacement.

Is there a recommended cleaning procedure for the lamp housing?

Yes. Use a lint‑free microfiber cloth lightly dampened with isopropyl alcohol to wipe the exterior. Avoid abrasive cleaners or direct contact with the quartz window, as scratches can impair UV transmission.

What safety precautions should be taken when handling the lamp?

Always wear UV‑protective eyewear and gloves when installing or servicing the lamp. Ensure the spectrophotometer is powered off and the lamp has cooled to ambient temperature before removal to prevent burns or accidental exposure to UV radiation.
