Medical grade oxygen description
Yuantong gas has a history of nearly 23 years in oxygen which is established on year 1995.Medical oxygen gas is colorless, odorless and tasteless. It is nonflammable. Almost all materials burn in air, burn much stronger force in oxygen. The atmosphere consists of 20.95 percent oxygen. At temperatures below -184℃ oxygen is in liquid form and has a transparent blue color, and is slightly heavier than water.
