The purity of each gas is 99.999%. The rare gases encapsulated in glass tubes can emit light under high voltage electric fields. Different gas elements will emit different light. It should be noted that the glass sealing gas is colorless and transparent. Please do not misunderstand that it is an empty pipe. Lighting must be done under high voltage electric field conditions. When the buyer receives the goods, please carefully open the box to prevent damage to the glass tube. Once there is any slight damage to the glass tube that cannot be seen by the naked eye, it will leak, resulting in inability to light. The inert gas pipe has reduced pressure and non reduced pressure. It is high-pressure and can only be lit by a high-power electric spark leak detector. Package Included: 1PC *Rare Gas.
