Re-finding Noah's laboratory

[MG Bait]

So I found the underdust laboratory for the quest and moved on. Later found out that I missed scanning the large storage container in there. Went to another underdust laboratory but it didn't have the large container to scan. So now I'm trying to figure out how to get back to the original underdust lab with Noah's lab and having no luck as I've wandered around for a bit since then. Have I just screwed myself out of the large container?

Once you travel far enough away from a tower, it disappears. You can't go back because its not there anymore. New ones are procedurally generated
But, the large storage box is always in the same place in each underdust. It will be there even if you already scanned it. Its not up in the laboratory or down in the tunnels, but behind one of the blocking flowers on the same level the elevator drops you off at.

Thank you! Seeing the boxes in the elevator and being unable to scan them made me think that was it for this zone. Then finding out there was another distinct scanable box was driving me nuts.
