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

is a double-bore quartz light source producing primarily 254 nm UV-C radiation, with additional ultraviolet emission capable of generating ozone. Featuring a 152.4 mm (6 in) lighted length, it is designed for photochemical, analytical, and ozone-generation applications using the Jelight PS-4 power supply.

Applications

Photochemistry and Chemical Research

The 90-0004-07 provides shortwave ultraviolet radiation for photochemical reactions, UV-driven research, and laboratory irradiation experiments. Its 152.4 mm (6 in) lighted length supports applications requiring an extended ultraviolet-emitting section within specialized equipment and experimental assemblies.

Ozone Generation and Environmental Research

The lamp produces ozone-generating ultraviolet radiation for controlled ozone-production experiments, environmental research, and gas-phase photochemical studies. Appropriate ventilation, ozone monitoring, and exposure controls are necessary during operation.

Analytical and Optical Instrumentation

Provides characteristic mercury emission for analytical instruments, spectroscopic measurements, and optical research applications. Its quartz construction and defined emitting section support integration into compatible laboratory instrumentation.

OEM and Laboratory Equipment Integration

The 152.4 mm (6 in) lighted length accommodates specialized laboratory equipment requiring a longer ultraviolet source than standard compact Pen-Ray lamps. Its one-ended electrical configuration supports installation within compatible chambers, optical assemblies, and custom research systems.

Frequently Asked Questions

How does the 90-0004-07 differ from the 90-0004-01?

The primary difference is lighted length. The 90-0004-07 has a 152.4 mm (6 in) lighted section, while the 90-0004-01 features a longer 228.6 mm (9 in) lighted section. Both produce primarily 254 nm UV-C radiation and use the Jelight PS-4 power supply.

How does the 90-0004-07 differ from the 90-0004-11?

The main distinction is the electrical termination. The 90-0004-07 includes a standard Pen-Ray connector, while the 90-0004-11 uses stripped electrical leads for specialized equipment connections. Verify the required connection configuration before selecting a replacement.

Which power supply is required for the 90-0004-07?

The Jelight PS-4 power supply is recommended for this lamp. It is available in 115 V (99-0004-01) and 230 V (99-0004-02) versions and is sold separately. Select the appropriate version for the available electrical supply.

Does the 90-0004-07 produce ozone?

Yes. In addition to its primary 254 nm emission, the lamp produces shorter-wavelength ultraviolet radiation capable of generating ozone in oxygen-containing environments. Appropriate ventilation, ozone monitoring, and exposure controls are necessary during operation.

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

Avoid direct eye and skin exposure to UV-C radiation by using appropriate UV-protective eyewear, shielding, and protective clothing. Provide adequate ventilation to control ozone exposure, avoid touching the lamp while hot, and disconnect the power supply before handling or servicing the lamp.
