A tall and elaborate glass apparatus on a black metal stand.
The glass apparatus has a funnel at its top extremity and a stopcock near its bottom. The apparatus features plastic fittings.
The glass apparatus is attached to a black-painted metal stand with an unpainted metal clamp. The clamp is adjusted using thumb screws. The stand has a rectangular footprint. The stand is corroded and appears to have been repainted.

This item was collected from the Department of Chemical Engineering in the Wallberg Building, room 203, on June 15, 2018.
An email dated 10 July 2018 from Alexander Dean of the Department of Chemical Engineering to Erich Weidenhammer, curator of UTSIC, reads in part:
“It sounds like the best description would be that this glassware was likely used for a phase-equilibrium experiment. It’s difficult to tell the exact use as there are components missing but it is likely that the solution is boiled through the chamber on the right side (Cottrell pump) where the liquid and vapour reach an equilibrium. It looks like there is an opening in the top of the chamber where a thermometer would be inserted to track the equilibrium temperature. ”
Further correspondence between Dean and a professor who owned (but did not use) this item at the Department of Chemical Engineering provided the following guess as to its purpose:
“My initial idea was that was a replacement apparatus for experiment P2, boiling point behaviour of a two component one phase system, but there don’t appear to be sampling ports — or at least not well designed ones. It’s certainly to do with measuring a boiling point of a fluid in some way — the crowfoot heater will boil the liquid which goes up the vertical Cottrell pump tube (where liquid and vapour come to equilibrium) and sprays onto a thermometer well. I can’t quite see if the condensate then returns to the boiling chamber, or if there’s a trap there.”
