Non Flammable Pure Oxygen Gas Rocket Fuel Oxidizer Electron Grade
Oxygen is the most abundant chemical element by mass in the Earth's biosphere, air, sea and land. Oxygen is the third most abundant chemical element in the universe, after hydrogen and helium.
Oxygen, which makes combustion possible and supports life, also constitutes about a fifth of the atmosphere. It is a pale blue, transparent liquid that is slightly heavier than water at temperatures measuring below 300 °F. Every material that is flammable in the air burns much more vigorously when exposed to this gas. Some combustibles, such as grease and oil, burn with almost explosive force if ignited in this gas. However, pure oxygen itself is not flammable.
Oxygen is a chemical element with symbol O and atomic number 8. It is a member of the chalcogen group on the periodic table and is a highly reactive nonmetal and oxidizing agent that readily forms oxides with most elements as well as other compounds. By mass, oxygen is the third-most abundant element in the universe, after hydrogen and helium. At standard temperature and pressure, two atoms of the element bind to form dioxygen, a colorless and odorless diatomic gas with the formula O2. This is an important part of the atmosphere and diatomic oxygen gas constitutes 20.8% of the Earth's atmosphere. Additionally, as oxides the element also makes up almost half of the Earth's crust.
Oxygen is necessary to sustain most terrestrial life. Oxygen is used in cellular respiration and many major classes of organic molecules in living organisms contain oxygen, such as proteins, nucleic acids, carbohydrates, and fats, as do the major constituent inorganic compounds of animal shells, teeth, and bone. Most of the mass of living organisms is oxygen as a component of water, the major constituent of lifeforms. Conversely, oxygen is continuously replenished by photosynthesis, which uses the energy of sunlight to produce oxygen from water and carbon dioxide.
1. Physical properties
|Commodity||High purity oxygen gas|
|Hazardous class for transort||2.2|
2. Typical technical data (COA)
|8ltr||1||100bar||According to the valve type|

|Other sizes and other standards are also available|
|Life support and recreational use||An application of O2 as a low-pressure breathing gas is in modern space suits, which surround their occupant's body with pressurized air. These devices use nearly pure oxygen at about one third normal pressure, resulting in a normal blood partial
pressure of O2.
|Industrial||Smelting of iron ore into steel consumes 55% of commercially produced oxygen. In this process, O2 is injected through a high-pressure lance into molten iron, which removes sulfur impurities and excess carbon as the respective oxides, SO2 and CO2.|
|Chemical||Ethylene is reacted with O2 to create ethylene oxide, which, in turn, is converted into ethylene glycol; the primary feeder material used to manufacture a host of products, including antifreeze and polyesterpolymers.|
|Other||Oxygen is used in medical applications, metal cutting and welding, as an
oxidizer in rocket fuel, and in water treatment.
