The box does have a gauge on it. I asked the lab folks if they look at it. 
They said their test was that if the gloves were poking out, then they 
knew it was ok. !!  I did remind them that once they graduate & go to a 
"real" job, recording things like pressure gauges in their lab book or 
checklist were considered basic requirements for any work. They said 
they'd set up a log sheet to do that. Can't make this stuff up!

If you are just looking to to ensure there are no leaks of gas from the 
box or into the box, you could do a pressure test to determine if the 
pressure  remains with an acceptable limit once filled with argon.  The 
opposite can also be done by performing a vacuum test, drawing a complete 
vacuum inside the box and determine if the vacuum holds then you would 
know that there are no leaks. 

You could also leak a container of liquid smoke inside the box, purge the 
box with argon or any other gas and once under pressure watch to see if 
any of the smoke escapes from the box.

Subject: [DCHAS-L] Glove box inspection checklist?

I have a lab that is using a glove box to maintain an inert atmosphere 
with argon while working with lithium ribbon. While the operation looks ok 
on the surface, they can't document or prove that they haven't had any 
failures (research labs are not production & no one ever thinks of these 
things!). Does anyone have a glove box inspection checklist or other info 
they can share? 

Thanks in advance for your help!
