I am hoping that someone can give me a measurement for a Hario Siphon filter. I am specifically looking at the TCA-3 (but 2 or 5 information would also be great).

I need to know the height of the bottom of the 'Lower Glass Bowl' when stood in its stand.

The reason I am after this, is I am trying to determine whether I'd be able to us a normal gas stove-top to work the siphon. If the bottom of the bowl (where the heat touches) is 10 cm (when on the stand) or less then it will be fine with my stove-top. (13cm or higher and it won't get hot enough I don't believe).
