what does the bottom black bit look like? is it sealed, a twist cap or what?

obviously the two thin areas are where you put rubber hosing, so im guessing most chemicals wouldnt go through there.

could it be to separate different gases or to bubble gas through a liquid?

A weird aspirator?

[fcknut]

if this is an aspirator you have made my day, how do I hook it up?

It's not.

It looks like some kind of adaptor, the precise utility of which would be become apparent only in the situation where you need it... ;)

If you were to use it as an aspirator, it'd back-fill with water and flood your set-up...

Pretty sure that's a small drying trap for nanoscale synths.

Make a bong from it and im sure it will be obvious :)
