It’s a modern alembic!
I wouldn’t use any stronger solvents than ethanol in it as it might melt the plastic bits.

I have experience with a similar device, it is manufactured in Singapore. I distill water in it for a sleep apnea machine. I have found that only 3
litres need to be distilled, otherwise the water smells because of the heating of the scale, there must be some organic matter in it. I thought about
distilling ethanol in it as well, but I wasn't sure about the safety. Of course, the seller only recommends it for water distillation, since it's
illegal to distill ethanol at home without a license. If I added KMnO4 to the water I could certainly then distill a slightly larger amount, but MnO2
or other manganese oxide-hydroxides would certainly deposit on the stainless steel. It is also recommended to add some alkaline hydroxide to the
drinking water before distillation.

I didn't notice any solid deposits in the water after it evaporated, so the problem was only with volatile organics.

So only good for alcohols with low boiling points?

I use this distilled water in a medical device and will use it for inorganic synthesis where minimal possible organic contamination doesn't matter.
When my supply of deionized store-bought water runs out. The water is boiled so it is hopefully sterile and that is important. I'm pouring it into the
storage bottle while it's still hot for disinfection.
