Dear Chem Fans,
Upon studying for the lab final, I came across something that
perplexed me. I was wondering which side of the rubber/Tefflon cap is
rubber, and which is Teflon. As I remember there is a rough dull side and
a shiny side. I never paid attention to this before, but the lab book has
mentioned it twice so I thought it might be important.
