If your ever in Northern Ontario Canada my employer has a an O2 plant that produces around 5,000 tosn of liquid O2 per day, I'm sure I could sneak out a few pounds of liquid
.LOL

Ya, in your coffee thermos, right?? :rofl:

Just for information - The Oxygen you breath in in the air is about 21%. A concentrator used for a nasal cannula will generate around 44% Oxygen. The only way to get 100% Oxygen is to purchase Medical Grade Oxygen. This is considered a "Drug" and you have to be an EMT or Physician to obtain it. I myself, work for a local Fire Department that fills their own Oxygen. They purchase "M" or "G" size cylinders and refill the small bottles thru a cascade system. If you have never filled a bottle such as a SCBA, remember that when pressurizing a cylinder, it gets mighty hot! You have to cool the bottle in cold water, and have an explosion proof container to place it in while refilling.
Hope this information helps -

The only way to get 100% oxygen is to buy medical grade? Funny, my local gas supplier never asks about my medical qualifications when I buy a bottle of oxygen for my torch. We can dance all around purity and various grades, but there's really no difference between a bottle of industrial oxygen and a bottle of medical (USP or NF) oxygen except the paperwork. The contents are likely from the same bulk container of liquid oxygen, and will be >99% O2, with a trace of N2 as the primary contaminant.

Used to work at a production plant that burnt a lot of steel parts. We got our liquid O2 tanks filled from a bulk truck. The driver told me a number of times that we his stop after filling the tank at the hospital down the road from us. He said "Yep,same stuff we just charge them more"

Never could get a response from the owner and the advert is gone, so I assume he sold it already. Oh well, I tend to believe it was what I already have for that low of a price...
