Sep.Funnel or what ?


Because I'm emigrating from UK I thought I'd 'stock up' on used Quickfit via eBay when suitable (cheap),
I just won this item that is described as 'Vintage Pyrex Separating Funnel Double Tap Laboratory Glassware'
but looks more like a gas sampling tube with 3-way valves.
Anyone know of a specific use for this configuration ?

Second one looks like a dean stark trap, but i think the first one has a gas liquid separation (or maybe addition) function, but I'm no expert!

i thought dean starks had a tap on one arm(left arm as shown above) letting you drain the lower phase.

I agree that the second photo is of a separator.
Some have taps and some, like this one, have graduated receivers,
e.g. determine water (or heavier fraction ) content of liquids.

I think that I could configure the first piece as a partial takeoff head. e.g.

oops! ... "downjere" = "down here" ... finger trouble and not checking properly :(

Found this in the glass shop at UC Berkeley. I believe it lived on the dean's desk for a while before it was broken. It has uranium glass connections and a strange green orb at the bottom.

Some kind of old fashioned sensor maybe? Density, viscosity.....?
