SPECTRUM TUBES: 50mm Capillary
Price range: $ 43.50 through $ 66.00 excl. GST
• These quality ‘Geissler type’ gas discharge spectrum tubes have an electrode at each end with a fine capillary tube in the middle which effectively demonstrates the spectral lines of pure substances with a colour discharge.
(Note: Items containing Mercury are prohibited in schools so the item EO-PH1196B-13 is not able for supply to schools.)
• Use intermittently and do not use as a lamp source.
*We offer a POWER SUPPLY, Spectrum Tube [IEC] EHV specifically for powering these tubes

(Wikipedia excerpt: .."...A spectrum (pl.: spectra or spectrums) is a set of related ideas, objects, or properties whose features overlap such that they blend to form a continuum.[1] The word spectrum was first used scientifically in optics to describe the rainbow of colors in visible light after passing through a prism. In the optical spectrum, light wavelength is viewed as continuous, and spectral colors are seen to blend into one another smoothly when organized in order of their corresponding wavelengths. As scientific understanding of light advanced, the term came to apply to the entire electromagnetic spectrum, including radiation not visible to the human eye. . ....")
