Glassware identification


Can anyone tell me what this piece of glassware might be ?

It looks to be some sort of bespoke receiver connector assembly that can separate vapours and hold them until they condense although i'm not sure why it doesn't have a tap on the vac connector. Not branded (presumably Chinese) joint sizes are 24/29 it's roughly 300mm by 300mm.

It is a distillation receiver.

It lets you remove fractions from the receiver without interrupting distillation while under vacuum.

Vacuum is applied to the tube at the top right of the picture and the lower right tube vents to atmosphere.

By manipulating the valves you put a collection flask on the bottom, evacuate it, fill it with disitillate, isolate it from the vacuum and vent it to the atmosphere so it can be removed.

They have advantages over cows in some situations.

Ebay says they need to get their hands on my bank account if I want to keep selling there.
This sounds like the best idea since putting ortho tricresyl phosphate in Ginger Jake.
