{"product_id":"water-vapor-spectrum-tube-sptwv01","title":"Water Vapor Spectrum Tube - SPTWV01","description":"The classic demonstration of spectral lines. These tubes acquaint students with the spectra of common gases in their pure form and are also used for demonstrating wavelength. Each gas has its own distinctive set of spectral lines when energized and viewed through a spectroscope. A spectrum tube power supply (not included) is required to energize the tubes.\nThe glass tubes are 25cm long with the capillary portion about 10cm long. An electrode is sealed in each end and attached to a metal end cap with a loop for convenient hookup to wire connections. Each spectrum tube includes an activity guide.\u003cbr\u003e\u003cb\u003eAdditional Info:\u003c\/b\u003e The classic demonstration of spectral lines.
