Jelight CL-3000L

is a microprocessor-controlled UV crosslinker designed for photochemical research and controlled laboratory irradiation at 365 nm. Featuring six 8 W UV-A tubes and an integrated radiometer, it delivers programmable UV energy or timed exposures within an enclosed, safety-interlocked chamber.

Applications

Fluorescence and UV-Response Studies

Provides controlled 365 nm UV-A exposure for studying fluorescent materials, dyes, and UV-responsive samples. Programmable irradiation supports repeatable exposure conditions during laboratory investigations.

Photochemical Research and UV Curing

Supports photochemical experiments and selected UV-curing procedures involving materials responsive to 365 nm radiation. Energy-controlled exposure allows researchers to establish consistent irradiation conditions using validated protocols.

Biomolecular and Membrane Crosslinking

Enables controlled UV-A irradiation for specialized biomolecular and membrane-based research where 365 nm exposure is specified. Crosslinking conditions should follow validated wavelength-specific protocols rather than standard UV-C procedures.

Features

• Microprocessor-controlled operation supports repeatable UV energy and timed exposures.
• Integrated radiometer calibrated to a NIST-traceable standard monitors accumulated UV energy during energy-controlled operation.
• Six 8 W UV-A tubes provide 365 nm longwave ultraviolet illumination within the chamber.
• Preset and user-defined exposure settings accommodate different laboratory procedures.
• UV-blocking viewing window and door safety interlock help reduce accidental UV exposure.
• Aluminum exposure chamber and protective UV sensor window support routine laboratory operation and maintenance.

Frequently Asked Questions

Can the CL-3000L be used for UV curing?

Yes, the CL-3000L can support selected UV-curing experiments involving materials or photoinitiators responsive to 365 nm radiation. Suitability depends on the material's curing requirements, delivered UV dose, and validated exposure conditions.

Is the recommended 120 mJ/cm² membrane-crosslinking dose suitable for the CL-3000L?

The manufacturer's general 120 mJ/cm² crosslinking recommendation should not be assumed optimal for 365 nm UV-A exposure. Follow the membrane manufacturer's instructions and a validated wavelength-specific protocol to determine the appropriate dose.

Which replacement tubes does the CL-3000L require, and is recalibration necessary?

The CL-3000L uses six Jelight 34-0006-01 replacement tubes rated at 8 W and 365 nm. The manufacturer recommends replacing all six together, and recalibration is not required when installing compatible tubes of the same wavelength.

Can the CL-3000L be converted to 254 nm or 302 nm operation?

Yes, the CL-3000L supports conversion to another wavelength by replacing all six UV tubes and recalibrating the instrument with the appropriate wavelength-specific calibration sensor. Simply installing different-wavelength tubes without recalibration does not ensure accurate UV energy measurements.
