Yes we have this as well. (it's chemistry, our is in the chem store.)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.
hi. sorry for the late reply.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.
