Spectral Tube (Helium) • SE-9462

This tube is one of eight that is used on PASCO’s Spectral Tube Power Supply and Mount (SE-9460). The 26 cm long tubes are capillary-thin over the middle 10 cm, providing sharp, bright spectra. Made of research-grade gasses and vapors and non-UV transmitting glass, these tubes produce spectral lines of high clarity.

Important Note:  To maximize the lifetime of this spectral tube, do not energize the tube for more than one minute at a time. Allow the tube to cool at least two minutes between uses.
