It's all theory based on my experience with much smaller much less dangerous things
than a 3 to 5 pound energy storage flywheel, (AKA DIY centrifuge for 100ml vials).
Please understand any of this will need plenty of testing, and strength of materials
analysis before you release it as a product.  But if you are only interested in DIY,
and won't do testing or analysis, please make the steel container out of
3/8" welded plate with a good weld on each seam, and then grind that down smooth
and put a 3/8" connector plate over the seam and make welds on each edge all along
its length for the full length of any seam.

Then cast concrete 9" thick around it and add plenty of 3/4" rebar that wraps all the way
around.  And the lid needs some real latch to hold it down during a flywheel explosion,
and a doglegged path out so nothing gets out at speed, not even liquid.  The lid needs to
be several inches smaller than the largest inside diameter of the containment chamber
so only bounces of random pieces hit it during the inevitable flywheel explosion.

So, wouldn't you rather make/buy a dinky one for 5ml vials and run more in series to
get your volumes?
