This Spectrum Tube Bundle is ideal for secondary schools and colleges, enabling clear demonstrations of gas emission spectra in physics and chemistry lessons. Teachers can easily illustrate the unique spectral lines of different gases, supporting practical investigations and spectrometer calibration.

The set includes four glass tubes, each filled with a different gas: hydrogen, neon, nitrogen, and oxygen. Suitable for use with compatible spectrum tube holders and power supplies (available separately, B8R08098).

• Includes 1 x hydrogen, 1 x neon, 1 x nitrogen, 1 x oxygen tube

• Each tube measures 260mm in length

• Maximum recommended running current: 3mA

• Recommended run cycle: 30 seconds on, 30 seconds off

• Strike voltages: hydrogen 2500–3500V, neon 2000–3200V, nitrogen 3000–4200V, oxygen 3000–4200V

• Glass body with metal end caps and constricted centre for concentrated discharge glow
