A chamber to control concentration of a vapor: Is there a name for this equipment? Mechanical engineer here so please excuse me if my question seems dumb to you!

I want to have a chamber $(\approx 40 \times 30 \times \pu{30 cm})$ to control concentration $(\pu{ppm})$ of a flammable material (e.g. alcohols or ketones) at a specific temperature $(T\approx \pu{24 \pm 10 ^\circ C})$ and pressure $(P\approx \pu{1 \pm 0.5 bar})$


  


What should this chamber be called? I need the the name to be able to search for it and also mention in my publication. 

Candidate names so far:


Incubator --> mostly for biological entities
Reactor
Environmental chamber --> too expensive
Atmospheric controlled chamber
Autoclave --> for sterilization(high temperature/pressure)
Flash drum
Vapor inhalation chambers --> for animal testing


P.S. I have posted the question also on Reddit here and here. There are some good points mentioned there.
There is a book The Design of Controlled-atmosphere Chambers for the Study of Oxygen Toxicity, so I suggest "contolled-atmosphere chamber".
