Spectral Tube (Carbon Dioxide) • SE-9464

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:  These spectral tubes should not have current run through them for more than 30 minutes continuously.
