CDM25 Replacement Bottom Beaker (For 25-Cup Cold Drip Towers)
This is a good quality item. The graduations are fairly accurate, and match the ones on the top beaker. The lid fits this beaker very well to keep dust out, but isn't water or air-tight. The glass seems a little thin, but I've bumped it into the counter a few times and it didn't even flinch, so it isn't too fragile. I'm happy with it.
