Jelight 8 W 302 nm Midrange UV-B Replacement Tube

is an 8 W replacement ultraviolet tube that emits midrange UV radiation at 302 nm. Designed for compatible Jelight EL Series lamps, CL-3000M Crosslinkers, and other UV laboratory equipment, it restores UV-B output for fluorescence examination, UV transillumination, and equipment maintenance.

Applications

Midrange Fluorescence Inspection

Restores 302 nm UV excitation in compatible lamps used to examine fluorescent minerals, dyes, specimens, and other UV-responsive materials. The replacement tube supports continued midrange fluorescence inspection when the original tube loses output or requires replacement.

UV Crosslinking and Transillumination

Provides replacement UV-B illumination for compatible CL-3000M Crosslinkers and laboratory transilluminators designed for 302 nm operation. Supports UV-dependent laboratory procedures and fluorescence-based sample visualization in compatible equipment.

UV Equipment Maintenance

Replaces worn or damaged 302 nm tubes in compatible Jelight EL Series lamps, CL-3000M Crosslinkers, and other supported UV equipment. Proper tube replacement helps maintain the intended performance of the existing lamp assembly.

Features

• Produces midrange ultraviolet radiation at a primary wavelength of 302 nm.
• Designed as an 8 W replacement tube for compatible Jelight and legacy UVP equipment.
• Features a linear T5 configuration with a G5 miniature bi-pin base.
• Supports selected EL Series lamps, CL-3000M Crosslinkers, and laboratory UV transilluminators.
• Supplied as an individual replacement tube rather than a complete UV lamp assembly.

Frequently Asked Questions

Which Jelight EL Series lamps use replacement tube 34-0042-01?

The 34-0042-01 is compatible with the UVM-18, UVM-28, UVLM-28, and UVLMS-38 EL Series lamps. The UVM-28 requires two 302 nm tubes, while the other listed models use one each. Additional tube positions may require different wavelengths or white-light replacements.

How many 34-0042-01 tubes are required for the CL-3000M Crosslinker?

The 302 nm CL-3000M Crosslinker requires six 34-0042-01 replacement tubes. The manufacturer recommends replacing all six tubes together to help maintain consistent UV output and crosslinking performance. Replacing tubes with the same wavelength does not require instrument recalibration according to the manufacturer's operating manual.

Can this tube replace the tubes in the CL-3000 or CL-3000L?

No, the standard CL-3000 requires 254 nm replacement tubes (34-0007-01), while the CL-3000L requires 365 nm replacement tubes (34-0006-01). The 34-0042-01 is specifically designated for the 302 nm CL-3000M Crosslinker.

What precautions should I take when replacing an 8 W UV-B tube?

Disconnect the equipment from power and allow the tubes to cool before replacement. Follow the equipment manual, handle the glass carefully, and verify that all UV shielding and safety interlocks are functioning before operation. Use appropriate UV-protective eyewear and skin protection, and never look directly at an exposed UV-B source.

How should used or broken UV fluorescent tubes be disposed of?

Handle used tubes as potentially mercury-containing fluorescent lamps and follow applicable recycling or hazardous-waste requirements. If a tube breaks, follow appropriate mercury-lamp cleanup procedures rather than treating the fragments as ordinary glass waste.
