EISCO premium spectrum tubes are of high quality and are designed for power supplies holding 26cm spectrum tubes. Features a large 10 centimeters capillary in the center for greater viewing area. These spectrum tubes are designed for operation intervals of 30 seconds and should be used for 30 seconds on/30 seconds off. These tubes effectively demonstrate the spectral lines of pure substances. Tubes require spectrum tube power supply. For intermittent use only, not to be used as a lamp source. Note: expected life of spectrum tubes will vary depending on the gas they contain. If the tubes are used as recommended and not allowed to overheat, the useful life, or time it takes to detect contamination with the usual measuring equipment is very long. Grades 8-16. For ages 13-21.
Features
- 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)
