Position of vapourisers on the backbar is important, especially if there is more then one vapouriser present. The more volatile anaesthetic agent should be places closer to the flowmeter.

Komesaroff and Stephens' anaesthetic machines are both examples of a vapouriser in-circuit machine. They are essentially a circle breathing system with one or more draw-over vapourisers within the circuit. They are economical due to very low required gas flows but disadvantages include possible overdosing and performance of vapouriser may be contaminated by water vapour.
