Jelight 90-0004-07 Mercury Pen-Ray UV Lamp

formerly designated as legacy model 3SC-6, is a low-pressure mercury light source providing primary 254 nm output across a 152.4 mm (6.0 in.) lighted length. Its double-bore quartz design supports integration into photochemical systems, ozone-generation setups, analytical instruments, and OEM equipment where a medium-length UV source is required. 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 90-0004-07 provides shortwave mercury UV exposure across a 152.4 mm (6.0 in.) lighted section, making it well suited for laboratory photochemical systems where a longer active region is needed without the size of a 228.6 mm (9.0 in.) lamp.

Ozone Generation and Environmental Research

The 90-0004-07 can be used in controlled ozone-generation and gas-phase photochemistry systems where shortwave mercury UV radiation is required.

Analytical and Optical Instrumentation

The stable mercury spectrum and strong 254 nm primary emission make the 90-0004-07 useful as a UV source in analytical and optical systems requiring predictable shortwave UV output.

OEM and Laboratory Equipment Integration

Its single-ended double-bore construction helps simplify installation into instruments, vessels, chambers, and custom assemblies where space and lamp geometry are important design considerations.

Features

• 152.4 mm (6.0 in.) lighted section provides extended UV exposure while fitting applications that do not require a longer 228.6 mm (9.0 in.) lamp.
• 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 specialized equipment.
• Quartz construction supports transmission of shortwave mercury UV radiation.
• Relatively low thermal output helps limit unwanted heating during UV-driven processes.

FAQs

What safety precautions are required when using the 90-0004-07?

Shortwave UV radiation can injure the eyes and skin, and this lamp can generate ozone. Operate the lamp only in appropriately engineered equipment using suitable UV shielding, eye and skin protection, ventilation, electrical safeguards, and ozone controls appropriate to the application.
