Spectrum Tube Power Supply
Spectrum Tube Power Supply (Product Code: SLE/PHY/301) is a mains-operated unit used to light gas-filled spectrum tubes so that their emission spectra can be studied in school and college physics laboratories. A common item of physics lab equipment in India for atomic-spectra lessons, it takes 26 cm tubes, and its enclosed box holds the tube firmly while stopping students from touching the electrodes. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is the Spectrum Tube Power Supply Used For?
When a high voltage is applied across the low-pressure gas in a spectrum tube, the gas glows with a colour typical of that element. Viewed through a spectroscope or diffraction grating, the glow separates into distinct bright lines rather than a continuous band, which gives students direct evidence that atoms emit light only at particular wavelengths. The black panel behind the tube makes this faint glow stand out even when the room lights are on.
Spectrum tubes run at high voltage, so tubes should be changed only by a teacher or technician with the unit switched off and unplugged, and allowed to cool before handling. Check that your mains supply matches the listed 220 V AC at 50 Hz, and that the tubes you plan to use are 26 cm long.
What to Specify When Ordering
- Your mains supply, so we can confirm it matches the unit's 220 V AC, 50 Hz input.
- The length of any spectrum tubes you already hold (the unit is designed for 26 cm tubes).
- Whether you also need spectrum tubes, and which gases.
- The viewing instrument students will use, such as a spectroscope or spectrometer.

Frequently Asked Questions
What length of tube does the Spectrum Tube Power Supply take?
The Spectrum Tube Power Supply is designed for 26 cm spectrum tubes. Its specially designed box holds the tube firmly in place, so check the length of any tubes you already own before ordering.
What mains supply does the Spectrum Tube Power Supply need?
The Spectrum Tube Power Supply operates on 220 V AC at 50 Hz. Buyers whose mains supply differs should tell us their voltage and frequency when requesting a quotation, so we can confirm suitability before supply.
Are spectrum tubes included with the Spectrum Tube Power Supply?
The listing for the Spectrum Tube Power Supply does not state that tubes are included. Tell us which gas tubes you need through the contact page, and we will confirm exactly what the quotation covers.
How does the Spectrum Tube Power Supply protect students?
The Spectrum Tube Power Supply holds the tube inside a specially designed box that prevents students from touching the electrodes, and a black panel behind the tube protects it from breakage. A teacher should still change tubes with the unit unplugged.
What is the output voltage of the Spectrum Tube Power Supply?
The output voltage of the Spectrum Tube Power Supply is not listed on this page. Please ask us through the contact page for the current specification sheet, which we confirm with your quotation rather than quoting unverified figures here.
