Spectrum tubes

Product Code : SCL-OS-12849

Spectrum Tubes by Educational Instrument are used to show how different gases emit characteristic colours and spectral lines when electrically excited. Each tube is intended for use with a compatible spectrum tubes power unit under trained supervision.

These tubes support hands-on learning in atomic physics, spectroscopy, wave optics, and modern physics. When viewed through a wooden spectroscope or diffraction grating, students can compare emission patterns and connect theory with observation.

Key Features

Used for atomic emission and line spectrum demonstrations.

Suitable for supervised school and college physics practicals.

Compatible with spectrum tube power supply units [confirm exact model].

Helps students compare different gas discharge spectra.

Useful for spectroscopy, optics, and STEM classroom activities.

Designed for visual demonstrations with a spectroscope or diffraction grating.

Gas types, tube quantity, and dimensions should be confirmed before order.

How to Use the Spectrum Tubes

Select the required spectrum tube and check that it is not cracked or damaged.

Place the tube into the compatible spectrum tube power unit.

Switch on the power unit only under teacher or laboratory supervisor guidance.

Observe the emitted light directly from a safe distance.

View the light through a spectroscope or diffraction grating to see spectral lines.

Record the colour and line pattern for comparison with other tubes.

Switch off the power unit before removing or changing the tube.

Safety note: Spectrum tubes operate with high-voltage power supplies. Do not touch the tube contacts while powered. Allow tubes to cool before handling.

Care & Maintenance

Store tubes in protective packaging when not in use.

Handle glass tubes carefully to avoid breakage.

Use only with a compatible power unit.

Keep tubes dry and away from impact, dust, and chemical vapours.

Frequently Asked Questions

What are Spectrum Tubes used for?

Spectrum Tubes are used to demonstrate the emission spectra of gases. They help students see how different gases produce different spectral line patterns.

Do Spectrum Tubes need a power unit?

Yes. Spectrum Tubes require a compatible spectrum tube power unit to excite the gas inside the tube safely and correctly.

Can Spectrum Tubes be used in schools?

Yes. They are suitable for school and college physics labs when used under trained supervision with proper electrical safety precautions.

Which gases are included in the set?

The exact gases must be confirmed before ordering. Common educational options may include gases such as hydrogen, helium, neon, or mercury, but the supplied configuration should be verified.

Can students observe the spectra without a spectroscope?

Students can see the tube glow without a spectroscope, but a spectroscope or diffraction grating is needed to observe clear spectral lines.

Are Spectrum Tubes safe to touch after use?

Do not touch tubes immediately after use. Switch off the power unit first and allow the tube to cool before handling.
