The power supply allows your students to view spectral lines using any of our spectrometers. Unlike other designs, there is no exposed high voltage. The gas tubes are permanently enclosed in plastic carriers that protect the tubes from breakage. There are no through-the-glass electrodes, so the tubes last far longer than older designs.
The included Spectrum Tube Fiber Optic Holder Carousel holds an optical fiber in position.
Each spectrum tube is sold separately.
WARNING: This product can expose you to chemicals, including nickel, which are known to the State of California to cause cancer. For more information, see www.P65Warnings.ca.gov
