# 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.

• Maybe environmental chamber? Welcome to Chemistry.SE by the way:) – andselisk Dec 8 '17 at 12:39
• @andselisk thanks for not burning me to the ground :) other SO communities are really hostile to newcomers. Environmental chamber seems very close to what I need. but it seems very expensive. Are there any smaller versions ($\approx 40 \times 30 \times 30 cm$) with not too many requirements? – Foad Dec 8 '17 at 12:43
• Good question; I don't really know, I'm sorry. I used a big one only once a decade ago, and yep, those were and are remaining expensive. Probably you can find a good deal on LabX, it's like an eBay for lab equipment. – andselisk Dec 8 '17 at 12:46
• they are indeed expensive! Thanks. I will keep searching. – Foad Dec 8 '17 at 12:49
• I would probably also add the dimensions or the volume of the chamber to the question. Also, the information whether the liquid and the vapors are corrosive might come in handy. – andselisk Dec 8 '17 at 12:53

There is a book The Design of Controlled-atmosphere Chambers for the Study of Oxygen Toxicity, so I suggest "contolled-atmosphere chamber".

• Thanks @davephd , I'm not able to find the source on the internet. is it a theses or something? do you have the PDF? It seems there are no off the shelve solution for me and I have to make anyway! – Foad Dec 8 '17 at 23:05
• Searching controlled atmospheric chamber on google mostly refers to glove boxes made by Plas-Labs. that's not what I'm looking for. – Foad Dec 9 '17 at 0:40
• from this comment: typically atmospheric tends to be reserved for situations where atmospheric gases are used instead of organic vapors – Foad Dec 10 '17 at 0:56
