How to make liquid oxygen, its a very interesting matter hope you will enjoy

Liquid Oxygen or O 2 is an attractive blue liquid that you can easily prepare yourself. There are several ways to make liquid oxygen. Oxygen from a gas in this one liquid uses cold liquid nitrogen.

Liquids that require oxygen content

1. Oxygen gas is a cylinder
2. 1-liter dwarf of liquid nitrogen
3. Test tube (about 200 mg)
4. Rubber pipe
5. Glass tube (fit inside the test tube)

Let’s get started

It should sit in a bath of a liquid nitrogen, so that a 200-ml test tube whip.

1. Attach one end of a length of rubber tube to the other end of an oxygen cylinder and a piece of glass pipe.
2. Place the glass pipe in the test tube.
3. Open the valve on the cracked oxygen cylinder and adjust the flow rate of gas so that there is a slow and gentle flow of gas in the test tube. As long as the flow rate is slow enough the concentration in the liquid oxygen test tube will start. It takes about 5-10 minutes to collect 50 ml of oxygen.
4. When you have collected enough liquid oxygen, close the valve of the oxygen gas cylinder.

Uses liquid oxygen

You can use liquid oxygen for the same project you perform using liquid nitrogen. It is used to enrich fuel as an immunity (for its oxidizing properties) and as a liquid coolant for rockets. Many modern rockets and spacecraft use liquid oxygen engines.

Security information

Oxygen is an oxidizer. It reacts very easily with flammable substances. According to the Canadian Center for Occupational Health and Safety (COCHS), materials generally considered non-profit, such as steel, iron, Teflon and aluminum, can ignite with liquid oxygen. Combustible organic matter can react to explosions. It is important to work away from a flame, spark, or heat source with liquid oxygen

Liquid nitrogen and liquid oxygen are extremely cold. These materials are capable of intense freezing explosions. Avoid skin contact with this liquid Also, take care to avoid touching any object which has been in contact with cold liquid, it can be very cold.
Dewars are easily broken by mechanical shock or exposure to extreme temperature changes. Take care not to hurt the giver. Not a cooling slam on a warm countertop, for example.

Liquid oxygen stops the formation of oxygen gas, which enriches the oxygen concentration in the air. Use care to avoid oxygen intoxication Work out of liquid oxygen or with well-ventilated rooms.


If you have liquid oxygen on your left, the safest way to free it is to pour it on an imperfect surface and allow air to circulate.

Interesting liquid oxygen fact

Although Michael Faraday (1845) dissolved most of the gases, he failed to liquefy oxygen, hydrogen, nitrogen, methane, carbon monoxide, and methane. The first measurable sample of liquid oxygen was produced in 183 by Polish professors Jizmunt Llovsky and Karl Olszowski. A few weeks later, the pair successfully formed liquid nitrogen.
