Vacuum tubes are typically evacuated of gases to create a vacuum inside. However, some specialized vacuum tubes may use inert gases like argon or neon to improve performance or provide specific characteristics.

To remove oxygen from a test tube, one method is to displace it with an inert gas, such as nitrogen or argon. By flushing the test tube with the inert gas, the oxygen is pushed out. Another method is to create a vacuum inside the test tube to remove the oxygen. This can be done using a vacuum pump or a syringe to pull the air out of the tube.
