Photochemical Quartz Lamps Pen-Ray®

Pen-Ray PCQ lamps are high-quality, low-pressure mercury lamps made of quartz, specifically designed for photochemical applications. They emit approximately 90% of their radiation at a wavelength of 254 nm, enabling targeted UV irradiation while generating significantly less heat compared to high-pressure UV light sources.

A variety of arc lengths and customizable configurations offer flexibility to meet diverse requirements in photochemistry.

Here, you will find a complete range of reliable, low-pressure PCQ Pen-Ray lamps.

Pen-Ray® PCQ-Lamps

Thanks to low-pressure technology and high-quality quartz processing, Pen-Ray PCQ lamps offer an alternative to high-pressure UV light sources, which are more problematic in terms of heat generation and safety considerations. Furthermore, the availability of various lamp lengths allows for flexible adaptation to different experimental setups.

Here you will find a complete product line of safe, low-pressure quartz (PCQ) lamps from the Pen-Ray brand.

The available models can be found under "Technical Data."
