Ultraviolet Crosslinkers

Chamber supplies uniform intensity overhead UV exposure of materials. The CL-1000 model is an exposure instrument, which utilizes shortwave ultraviolet energy to bond the DNA to a medium.


• Shortwave 254nm UV: UV crosslinking membranes

• Longwave 365nm UV: UV curing, non-destructive testing

• Midrange 302nm UV: Photochemical reactions, UV crosslinking

Main Features

  • Small footprint for benchtop use

  • Preset and manual controls for ultraviolet or time exposures

  • Preset exposure delivers 120,000 microjoules or five minutes of exposure

  • Microprocessor measures and control UV output, ensuring maximum energy efficiency

  • Large LED display and touch panel which displays time or energy settings

  • Window on the door allows viewing of the process yet blocks out the UV radiation

  • Select from models with 302nm midrange UV, 365nm longwave UV or 254nm shortwave UV

  • Overhead UV supplies uniform UV

  • Shortwave UV model is available with choice of door (CL-1000) or drawer (CX-2000) styles

  • Built-in UV sensor is calibrated at the UVP factory to ensure accuracy and reliability

  • Crosslinking for attaching nucleic acids to a membrane takes seconds as compared to oven baking

"The DNA Damage Project: The Socrates Fellows program, funded by the National Science Foundation, is a UCSD project run by BioBridge which partners graduate students with local high school teachers to bring current science into the high school classroom. The use of a UV crosslinker, provided by UVP, allowed one Socrates fellow to develop and implement a meaningful biotechnology experience with high school students exploring the concept of DNA damage."
