Jelight 90-0004-01 Mercury Pen-Ray UV Lamp

formerly designated as legacy model 3SC-9, is a low-pressure mercury light source providing primary 254 nm output across a 228.6 mm (9.0 in.) lighted length. Its double-bore quartz design supports compact integration into photochemical systems, ozone-generation setups, analytical instruments, and OEM equipment. The lamp uses a standard Pen-Ray connector and is designed for use with the Jelight PS-4 power supply.

Applications

Photochemistry and Chemical Research

The 90-0004-01 is well suited for laboratory photoreactions requiring shortwave mercury UV exposure over an extended area. Its long illuminated section can be incorporated into reaction vessels, experimental UV reactors, flow systems, and other photochemical setups.

Ozone Generation and Environmental Research

The 90-0004-01 is designed for applications including ozone production. Its mercury UV output can be incorporated into controlled ozone-generation systems, gas-treatment experiments, ozone research equipment, and related environmental instrumentation.

Analytical and Optical Instrumentation

The stable mercury spectrum and strong 254 nm emission make the 90-0004-01 useful as a UV source in analytical and optical equipment where predictable spectral output is important.

OEM and Laboratory Equipment Integration

The single-ended double-bore construction helps simplify installation where access is limited or where a long UV-emitting section must extend into an instrument, vessel, chamber, or process area.

Features

• Extended UV-emitting region provides broad exposure for photochemical reactors, ozone systems, and larger experimental assemblies.
• Strong, stable low-pressure mercury output supports repeatable analytical, optical, and research applications.
• Double-bore construction places electrical connections at one end for easier integration into confined or specialized equipment.
• Relatively low operating temperature helps reduce unwanted thermal loading during UV-driven processes.
• Quartz construction supports transmission of shortwave mercury UV radiation.
