1865-3 Borosilicate Glass Spectrum Tube with Helium Gas. 26cm

Spectrum Tube with Helium Gas. Made from borosilicate glass and containing helium gas under a low-pressure vacuum. The length is 26cm and made to fit a standard Spectrum Power Supply. Used in spectrum analysis in science education classrooms.

• The Helium Gas Spectrum Tube is a sealed glass tube containing Helium gas at low pressure, designed to emit characteristic light when ionized by a high-voltage power supply. You can use our 1865-PS Power Supply.
• The Helium Gas Tube will produce a soft pinkish glow with distinct emission lines in the violet, blue, green, and yellow regions of the spectrum, showcasing helium's unique spectral signature.
• Commonly used in teaching the principles of emission spectra, atomic energy levels, and the properties of noble gases in science education.
• Demonstrates electron excitation and de-excitation processes, photon emission, and the relationship between atomic structure and emitted wavelengths.
• The Helium Gas Spectrum Tube is 26 centimeters long and fits our 1865-PS Power Supply. They are individually labeled with the symbol for the gas. Well packed in triangular tubes with foam protecting the ends of the tubes to ensure they arrive in good condition.
