Just as an aside, I once had a $500 \cdot m L$ sep flask with a plastic stopcock that had never been used for chemicals, and used it for the express purpose to make the gravy when I was cooking a roast - i.e. drain the fat and roasting juices into a sep funnel, and the juice from the meat would collect in the bottom half, which of course you could drain off to a separate pan to make the gravy.
