Product Description

EISCO spectrum tube is used for demonstrating spectral lines of pure substances, and contains krypton (K) gas under pressure to produce light for spectral analysis. The tube has a 10.0cm capillary in the center for observing light wavelengths, and is straight form with side electrodes for conductivity. The tube measures 26.0cm (H), and is made of glass for transparency and resistance to heat. (H is height, the vertical distance from the lowest to highest point.) Glass is an inert brittle solid, heat-resistant, and typically transparent. It is relatively easily cut and shaped. The tube requires a spectrum tube power supply for operation (sold separately), and should be operated at 30-second on/off intervals for longer product life and safer use. The tube is suitable for high school or college students, or ages 13 to 21.Science education products incorporate applied math and science principles into classroom and homeschool-based projects. Teachers in pre-K, elementary, and secondary classrooms use science education kits and products alongside science, technology, engineering, and math (STEM) curriculum to demonstrate STEM concepts and real-world applications through hands-on activities. Science education projects include a broad range of activities, such as practical experiments in engineering, aeronautics, robotics, energy, chemistry, physics, biology, and geology.EISCO Scientific manufactures and supplies lab equipment for education and industry. The company, founded in 1968 and headquartered in Rochester, NY, meets International Organization of Standardization (ISO) standard 9001: 2000.
