YZDKJZ Spectrum Discharge Tube, 6 Rare Gas Glass Tubes, Each Tube Has A 27cm Unit Length/height And Is Labeled, 11cm Width Per Unit, For Chemistry & Physics Education, (without Excitation Base)

YZDKJZ

[Spectrometer Tube Set] ：This set includes six sealed gas tubes, each 27 cm long/height and 11 cm wide. Each tube emits a unique and vibrant fluorescence when powered, making them easy to distinguish. [Note] ：Operation requires a gas excitation power supply, which must be prepared separately; the recommended operating voltage is approximately 5KV, not exceeding 10KV. [Visual Spectral Demonstration] ：Each tube is labeled: Spectrometer Tube Set: He, Ne, Ar, H2, N2, Hg. It clearly displays the characteristic emission spectra of inert gases, helping students and science enthusiasts intuitively understand atomic structure and spectral line principles. [Safe and Durable Construction] : The sealed glass tubes and stable base ensure safe operation in classrooms and laboratories. Highly crafted, durable, and with stable performance. [Ideal Choice for Education] : Ideal for secondary school chemistry and physics courses, science exhibitions, and laboratory demonstrations. Allows direct observation of atomic emission and high-pressure glow discharge phenomena.
