A simple question. When purchasing a nitrogen tank, what grade of nitrogen do you look for?

Just standard run of the mill welding grade? ( in the usa).

What size tank should one get?

thanks

Southwinds, I politely point out that your questions have been discussed before in the most minute detail. Do a search with "nitrogen" and/or "nitrogen tank" and you'll find TONS of posts about it.

Have you tried doing some research ?
This site also has a very good search function (and advanced search).
Try using that to search, research, and read up.

Perhaps also check what the PPH has to say :
note : When viewing, go into list view if not already (use button in top right corner), and click "name" to order things correctly (should see an arrow pointing up, or click "name" again)
* CAVEAT * : Scammers may edit documents and change seller's contact details to the scammer's contact details. Some hosted documents are editable, so a previously checked document could still be compromised. You use this document *ENTIRELY AT YOUR OWN RISK*. It is *ESSENTIAL* that you cross-check information with someone having an up-to-date and trusted version, or with some other means of verifying the information. This includes email / website addresses, telephone numbers, information, dosage levels, and any and all information in the document. If you do not *fully* understand these statements then please do *not* use this document !

YES I have been doing research about Nitrogen and have yet to find any threads that state specifically WHAT CONCENTRATION one needs to CTB. Industrial grade for welding? 90% ? 95%? 99.5 %, food grade? Medical grade? Perhaps you could direct me to the thread that states this? I have spoke with local suppliers and they all have varying concentrations.

You want industrial- or welding-grade nitrogen which should be advertised as 99% pure by the company you're looking to by it from. Avoid any other form of nitrogen.

You can also use another inert gas called argon. Again you want industrial/welding grade at 99% purity. There's nothing inherently special or superior about nitrogen for the exit bag method.

Food grade is also 99.99%. Thats what I took.

What is food-grade nitrogen? Have to admit I'm not familiar with that. The industrial/welding kind is always talked about here so that's what I recommended.

Food grade nitrogen is very pure over 99%. Beer Nitrogen is only 70% mixed with and contains 30% CO2.

Do some research. Stop asking other people. There is a huge resource section on this site alone.

I don't understand why people have to be so nasty to people asking questions that has already been answered. So what it has already been answered. If you don't want to answer then shut your mouth and pass it by.

Actually I agree with your statement. Major blood problem issues here, and apparently when the reading goes over 153/120 I become impatient and obnoxious. Just found that out. So I do apologize for the way I put it. Unfortunately I can do nothing about what was. I can only be aware of the symptoms precluding such an event and NOT try to communicate when the levels are high. Thank you for pointing this out.

I sent them a pm anyway. My apology at the time was a terse answer to their questions, but still that was nasty. Seems when the BP skyrockets nasty and terse is all I can be...hopefully this will all be over by March...

Hey Poof, having a bad day? Sounds like it. If you READ MY POST CAREFULLY, I was asking about the specific concentration of Nitrogen as I HAVE BEEN DOING RESEARCH and have not found clear answers on that question. Hope your feeling better today.

Is the nitrogen used to push out wine from dispensers, to no alter taste and other parameters of wine, a 100% pure inert gas is needed, and the nitrogen is the standard.

Same grade of purity is also used for racing cars tires, 100% pure nitrogen too to have costant pressure in high speed environment.
