Apparently this Lexan/polycarbonate plastic, used in Nalgene bottles and the receptacle bottles for distillers (Recycling symbol #7), as well as MANY OTHER items, contains and releases Bisphenol-A (BPA).
I am not comfortable with this. I haven't ever used this plastic until I got a distiller. I will be switching NOW to something else. I will look for glass, long-term but even a ceramic casserole dish will do until then.
