Helium Grades

[fdog]

Where's the best place to pick up a couple of T-bottles? I would love to have my own bottles so I wouldn't have to rent them.

Can't say about the T cylinders, we purchased our K cylinders as part of the initial fill...the vendor, Airgas, just tacked on the extra $.

All the best, James

Do you know how much they usually sell for?

I wish you wouldn't keep bringing up the cost of He - we get seriously screwed here, I just had to pay the equivalent of $240 plus delivery for a J of He - and I have to go and get it from the ferry terminal 20 miles away

Could be worse - try getting it in the Canary Islands..

What grade of helium is your choice. do you splurge on research grade or go for the straight baloon grade and save some cash......or anything in between

I just ordered two bottles of industrial grade.

This is a useful link about helium.
Helium - Electronic, Research and other specialty grades. Properties, Purity and Packaging, Helium - He - Helium is a colorless, odorless and tasteless gas. It is present in dry air in a concentration of 5.24 ppm by volume. Used extensively in the we

No way does helium contain oxygen as technical grade can be used for welding.
Also they cannot sell a product as helium if it does not have a minimum level of purity.
Adding enough O2 to be able to breath it and not pass out (at sea level)
would have to be significantly greater than 10%.

Technical grade is 99.9% pure
High purity 99.995
Ultra high 99.999

I know a lot of people that have been using the tech grade for years.
I use the High Purity. We are all probably getting more contaminants from
the compressor air than from bottled helium.

I use whatever the welding supply ships me. Costs 70 for a K bottle. Hasn't killed me yet

EDIT -- I bring him lobsters so he doesn't charge me rental.

I am using ultra high purity helium. I also use aviators breathing oxygen (ABO).

The cost difference isn't worth the liability.

There is no specification for baloon grade helium. It may be mixed with oxygen or it may be mixed with air and the ratios are highly variable. The only thing you know for sure is that there is enough helium in the mix to float a baloon.
