The filling volume of the new Vapor 2000 and the electronic D-Vapor amounts to 300 ml. This means you can completely empty the entire contents of a standard anaesthetic agent bottle containing 250 ml into the vaporiser. Even if the vaporiser still contains remnants of your anaesthetic agent, you can top it off with an entire, new bottle. This not only speeds up your workflow. Since you can refill the anaesthetic agents in one step, you also do not have to worry about keeping any leftovers safe and secure.
