This thread brings back some old and not so fond memories. I initially started trying to buy Medical Grade Oxygen for partial pressure blending about 12 years ago. Air Liquide would not sell it to me without a "prescription." Being an R.N. and EMT-Paramedic getting said prescription was easy. When I presented the prescrition to Air Liquide they then said "we are not pharmacists."
This was at the plant where air was actually cooled enough to get liquid Oxygen and Nitrogen. Thousands of cylinders were filled there everyday. Same manifold for every grade.
