A good separator. Separator funnels are used to separate two liquids which don't mix together and form phases, like water and oil do. I prefer this one even compared with one made in the EU, which did cost five times as much, since it's well made and leak-proof. Nevertheless one critique and advice: Don't use the glass stopper if you plan to shake it (which is standard procedure after you filled the liquids in). Get one made from chemical resistant plastic instead (Polyethylene as example, but check a "chemical plastic resistance chart" before you use it) . When you shake it one hand secures the stopper, the other the outlet. Since many chemicals will release gases when you shake them turn it around afterwards (so the outlet is pointing upwards, but away from you) and release the gases through it. Don't release them through the inlet, since tiny drops of liquid will splash in all directions. Not much, but especially with acids or especially with lye might be enough to damage your eyes, skin or clothes.. That's also why you shouldn't use the glass stopper - it will either "bake" with the glass around it, since glass on glass tends to jam if force is applied in a not ideal way (which will happen while you shake it and secure the stopper). Or you use grease or silicon, which makes it too slippery for shaking and the grease will find it's way in, mostly sooner then later.
