Simple Argon Source
Hopefully some may find this useful, as getting a full tank of argon can be very cost prohibitive and I haven't seen any other mentions of this on the
forum.
Here we have a small pressurized can of argon gas for a pretty decent price if you are just doing some small jobs such as ampouling some samples under
an inert atmosphere. According to the label and MSDS it contains only argon.

Cost effective? Not at all, but might be useful for some who dont need a large tank.

Hey, that's a nice find j_sum1, any idea how much argon is actually in one of those bottles?

Enough for some ampoules. Enough for me to make my own gas discharge tubes. I have questions about the nozzle, but there's only one way to find out.
I couldn't find a similar nitrogen product however. Seems like you have to go to welding suppliers and buy a large bottle.

It contains 12 g of argon (6.7 L).
I bought one of these to preserve recently purchased lithium ($12.50 shipped). I have found it locally (Austin Hardwood) for $8.50.
I just sprung for $80 for a 20 ft^3 (550 L) argon cylinder from Harbor Freight, so that will be the only Bloxygen can I will ever buy.

There is a "half way house"
https://www.machinemart.co.uk/shop/product/details/argon-gas...
you need a regulator, but it's still less of a capital investment than a full size cylinder.

AirGas also sells argon cylinders - I have a local shop with a showroom that you can just walk into and buy whatever. I bought a 40 ft3
tank, a flowmeter regulator, and some fittings for just shy of $200. Not too bad considering it will last me practically forever. And if I do run out,
all I need to do is exchange the cylinder for a full one for only $30.
I can also attest to the quality of the Bloxygen cans. I bought a few for lithium protection as well. My lithium has been stored in a tightly sealed
screw cap bottle with gas-tight teflon tape for about 6 weeks, with no visible corrosion to the Li. (well, no more than was there initially)

TY Bob – this is just the ticket for small scale stuff and backfilling reagent bottles. I wrote to the guy about purity, wondering if they, "cut",
their product with anything. Here is his response:
Hi Phil,
We only use ultra pure argon. 5x9 is the spec…99.999% pure. I imagine that some air contaminates this mixture during manufacturing, but we buy the
best Argon we can.

if you only need argon every now and then, befriend someone with a MIG or TIG welder. I stored some REEs and strontium the other day, and for
interest I checked the bottle weight before and after. I used it on low flow (4 litres/minute for about 20 minutes). could not measure a difference in
weight. so I guess a stubbie each at the end of the day squares it up  his
bottles are about 1.6M tall and he only pays AUD70 to fill them up.
another mate of mine has built a connector that allows 3 bottles to be joined together. the 3 blokes all put in to buy a refill in the "legit" bottle
that the distributors know about, and then decant into the other 2 bottles. when the pressure evens out, each one has 1/3 of the gas. enough for home
welder odd job use for a year. cheeeeep 
think outside the box and save bucket loads
