100L Distillation, rectification reflux reactor for sale

Hey, Guys
Andy comes again, as I said we have two 100L distillation, rectification reflux reactors for sale.
Here attached its pics, DM me or email: andydu@effison.cn

How about some info on what this is used for

It is like a short path distillation, use a rectification column instead of the gas phase column.
Here attached the drawing of 50L round flask reactor, pls check.
