I recently acquired some old glassware from a university sale, and I have a couple of pieces that I have not seen before. Can anyone assist me in identification? The first item appears to be meant for gas samples. It has a stopcock on both ends and has a large space between. The gas inside is NO2. The second looks like an addition funnel with a water cooled stem.
