Need help in obtaining a suitable drawing for [[Vacuum Distillation]]

[Milton Beychok]

Hello all:

Yesterday, I created a new CZ article [[Vacuum distillation]]. The article has two main sections: "Vacuum distillation in petroleum refining" and "Laboratory-scale vacuum distillation".

The laboratory section has a sub-section describing the use of the "Perkin triangle apparatus" for vacuum distillation of air-sensitive material. That section needs to be enhanced with a drawing of the Perkin triangle apparatus that can be uploaded into CZ. A drawing would be preferable rather than a photo.

An example of such a drawing exists in the Wikipedia "Distillation" article but the author of that drawing has declined giving us his real name, so we cannot obtain his drawing from Wikimedia Commons and upload it into CZ.

Can any of you provide a similar drawing that we can upload into CZ? Failing that, can any of you provide a good, clear photo of the Perkin triangle apparatus?

I would be most appreciative of any help in this matter. Thanks in advance, Milt Beychok
