Equipment identification help?

We use the first to show the amount of oxygen in air heating copper turnings. You need perfect seals between gas syringes etc or the air leaks out. Haven't used it in years as its almost impossible to get to work properly.
Yes we have this as well. (it's chemistry, our is in the chem store.)

Would anyone be able to tell me what these are? I was assuming these were used in physics but the physics teacher doesn't seem to think it is.
hi. sorry for the late reply.
the first is the portable bench for finding composition of %O2 in air using copper turnings or wire and needs a small bunsen burner to enable the heating of the copper.- i have labelled mine as copper oxidation bench
hope this is helpful - albeit a bit late :)
