Eisco Labs Premium Spectrum Tube - Nitrogen (N), 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)
