Offering for bids is this odd sort of Chemistry Laboratory glassware.THis as you can see is a glass cylinder 9 inches tall with just over 3 3/4 inches diameter with another glass flask/bulb in the middle of it. There is a relief tube connected to the bulb to the cylinder with a hole in it to the outside.It has a round upper lip but the bottom is formed to fit something as I hope the pics show.
