Jelight CL-3000M

is a microprocessor-controlled UV crosslinker designed for biomolecular research and controlled laboratory irradiation at 302 nm. Featuring six 8 W UV-B tubes and an integrated radiometer, it delivers programmable UV energy or timed exposures within an enclosed, safety-interlocked chamber.

Applications

Controlled UV-B Irradiation and Research

Provides programmable 302 nm UV-B exposure for laboratory research involving UV-induced biological and molecular changes. Measured energy delivery supports repeatable irradiation conditions for experimental procedures.

Biomolecular and Membrane Crosslinking

Supports DNA and RNA immobilization on compatible membranes when 302 nm irradiation is specified by the laboratory protocol. Programmable UV exposure allows researchers to establish controlled crosslinking conditions for applicable membrane-based procedures.

Photochemical and UV-Response Studies

Enables controlled irradiation of samples and materials responsive to midrange ultraviolet radiation. Suitable for wavelength-dependent photochemical research, fluorescence studies, and selected UV-curing experiments using appropriate protocols.

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-B tubes provide uniform 302 nm 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 quartz sensor window support routine laboratory operation and maintenance.

Frequently Asked Questions

Can the CL-3000M replace the 254 nm CL-3000 for UV-C disinfection?

No, the CL-3000M operates at 302 nm UV-B and is not a direct substitute for the 254 nm CL-3000 in procedures requiring UV-C irradiation. Select the appropriate wavelength and validated exposure conditions for the intended application rather than assuming equivalent disinfection performance.

Is the recommended 120 mJ/cm² membrane-crosslinking dose appropriate for the CL-3000M?

The manufacturer's operating manual identifies 120 mJ/cm² as a recommended dose for nucleic acid immobilization, but this setting should not be assumed optimal for every wavelength or membrane. Follow the membrane manufacturer's instructions and a validated 302 nm protocol to determine the appropriate exposure.

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

The CL-3000M uses six Jelight 34-0042-01 replacement tubes rated at 8 W and 302 nm. The manufacturer recommends replacing all six together, and recalibration is not required when installing compatible tubes of the same wavelength.

Can the CL-3000M be converted to another UV wavelength?

Yes, the CL-3000M can be converted to another supported 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.
