In precision analytical instruments, deuterium lamps are the core of UV light sources, directly determining detection accuracy and stability. The L2D2 Lamp series by Hamamatsu (Japan), with breakthrough technology and excellent performance, has become the preferred accessory for laboratories worldwide, providing reliable light energy support for HPLC, UV-Vis spectrophotometers and other equipment.
Core Technological Breakthrough: Reshaping Deuterium Lamp Performance Standards
L2D2 Lamp stands out with comprehensive technological innovation. It adopts a ceramic-optimized structure to fix electrode spacing, greatly improving thermal stability. Its intensity fluctuation is halved compared to traditional deuterium lamps, with an output stability deviation of ≤±0.3%/h and a typical fluctuation peak (p-p) as low as 0.005%, laying a solid foundation for trace detection accuracy.
The series includes two models: L2-2000 (2000 hours) and L2-4000 (4000 hours). The latter has a lifespan four times that of traditional deuterium lamps, significantly reducing maintenance costs. Light output intensity is increased by 30% and 10% respectively, providing high-intensity continuous spectra in the 185-400nm full UV band to meet various analytical needs.
Its transparent electrode structure supports linear arrangement of light source and optical system, reducing light loss. It maintains the optimal cathode operating temperature without additional power supply, and its stable working voltage of 3.5V±0.5V is compatible with mainstream instruments, simplifying integration and operation.
Versatile Compatibility: Covering Full-Scope Precision Analysis
With excellent compatibility, L2D2 Lamp can match HPLC detectors such as Shimadzu LC-10A and SPD-10A (part No. 228-34016-02), accurately capturing trace targets in pharmaceutical, food and environmental testing. It also adapts to spectrometers, capillary electrophoresis instruments and other equipment, covering multiple industry scenarios.
The series includes derivative models like L6565 and L6585-02, with supporting power supplies provided by Hamamatsu. Even if some models are discontinued, new inventory can still be obtained through professional suppliers, with a 1-year warranty and 30-day return/exchange service to ensure stable equipment operation.
As Hamamatsu’s flagship deuterium lamp, its long lifespan, high stability, and high efficiency reduce laboratory operating costs and provide reliable data for scientific research. It will continue to be an industry benchmark in the future, offering core light source guarantees for global scientific research and testing.
