Product Description
The Jelight 78PA-2046-2 is a professional-grade, cold cathode mercury vapor lamp engineered for high-precision scientific and industrial UV applications. Utilizing Jelight’s proprietary Double-Bore® design, this lamp features a quartz septum through the center that allows plasma to travel in a continuous arc, providing unmatched stability and uniformity. Because this "78" series model is constructed from Synthetic Silica, it is an ozone-producing light source, transmitting the critical 185 nm line required for organic carbon oxidation and ozone generation.
Condition Detail: New - Open Box. This item is in new, unused condition. The original protective packaging has been opened to confirm technical specifications and for photography.
Critical Equipment Compatibility: This lamp is a high-demand replacement component for precision laboratory instrumentation, including: TOC Analyzers: Replacement for Anatel PAT700, Anatel A-643a, and Sievers/Suez M9, 500RL, and 900 series. Analytical Instruments: HPLC Detectors, Spectrophotometers, and Spectrometers. Industrial Units: Jelight Model 12/256 UVO Cleaners and Ozone Generators.
