Eisco Labs Premium Spectrum Tube - Neon (Ne), 26cm

Eisco Labs Premium Spectrum Tube - Neon (Ne), 26cm

• HIGH-QUALITY DESIGN || Eisco's spectrum tubes are designed with a greater viewing area for clearer observations.
• OBSERVING THE SPECTRA || These Spectrum Tubes use research-grade gasses and vapors to provide bright-line spectral lines of the highest clarity. They are designed for optimum intensity and line resolution when examined in a student-grade spectrometer equipped with a ca.200 line/mm (5000 line/inch) diffraction grating.
• SPECTRUM TUBE POWER SUPPLY || Tubes should be energized with the Spectrum Tube Power Supply, which is made expressly for this purpose. Tube life is extended if operation is cyclic for no more than 30 seconds "on," 30 seconds "off," etc., increasing the usable life of the tubes.
• PRODUCT DIMENSIONS || Each Spectrum tube measures 26cm long (10.24 Inches)

<div class=€aplus€><p>EISCO spectrum tube is used for demonstrating spectral lines of pure substances, and contains neon (Ne) 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.</p><p>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.</p><p>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.</p></div>
