Meaning and Definition
An early type of low-pressure gas discharge tube, used historically to demonstrate and study the phenomena of electrical conduction in gases, often producing glowing light.
Any sealed glass tube containing a rarefied gas (or gas mixture) with electrodes at each end, which emits light when a high voltage is applied. It is a precursor to modern neon signs, fluorescent lamps, and cathode-ray tubes.

FAQ
Frequently Asked Questions
It was invented by the German glassblower and physicist Heinrich Geissler in 1857.
Not exactly. A neon sign is a direct commercial application of the principle discovered and demonstrated with Geissler tubes. The Geissler tube is the simpler, earlier experimental apparatus.
Various rarefied (low-pressure) gases were used, including air, nitrogen, carbon dioxide, and later, noble gases like neon, each producing a different colour of glow.
They were crucial for early research into electrical conduction in gases, leading to the discovery of cathode rays, X-rays, and the electron, and fundamentally advancing atomic and plasma physics.
An early type of low-pressure gas discharge tube, used historically to demonstrate and study the phenomena of electrical conduction in gases, often producing glowing light.
Geissler tube is usually historical scientific / technical in register.
