This should be a modified fractionation device similar to a distillation head. Only the designer can give it a specific name...because it is not a mainstream instrument~
You can infer its function by yourself , you see, the long and thin tube in the upper left corner has a condensation effect. When the piston is closed, the condensed liquid is blocked on the right side, while the uncondensed substance is still in gaseous state and flows along the upper opening. to other devices to separate it from the condensed matter; after the separation is complete, the condensed stuff will collect in a large thick tube on the left. At this time, open the piston and flow back along to achieve separation. role.
Compare the difference between it and the ordinary distillation head. In the ordinary distillation head, the condensed material flows back to the heating place and continues to be heated; but this is not the case. Once the condensation is separated, the liquid material is no longer heated and evaporated. So I think it can be used to separate substances with intermediate boiling points, that is, to separate the one with intermediate boiling points from three substances.
The ones with the highest boiling point are always liquid and have not been evaporated and are always at the bottom; the ones with the lowest boiling point are still gaseous after condensation and go from the top. The remaining boiling points are in the middle and are collected on the right. In the collection tube, after the final fractionation is completed, the piston can be opened to flow away from the bottom. You only need to replace it with a collection bottle below. It is quite convenient to think about it~~~
I thought about it for a long time. ~Hope to adopt~ Hehe

I asked again for you. The expert in chemistry said it is a constant pressure dropper. Liquid funnel, the spiral on the right is probably used to control the flow rate.
I really can’t bear to delete my answer above, I’ve been thinking about it for a long time = =…I hope you will adopt it…
