Voltameter in TeX?

Question

Hello I wanted to draw a Hofmann voltameter in TikZ like in this image:

Unfortunately, there are a lot of curves and shapes that are tedious to draw. Is there an easy way to draw it or do I have to settle for something like this

\begin{tikzpicture}[xscale=0.7]
\filldraw[black!50!white] (0,0)  to[line to] (0,4.5) to[line to] (2,4.5) to[line to] (2,2) to[line to] (4,2) to[line to] (4,5) to[line to] (6,5) to[line to] (6,2) to[line to] (8,2) to[line to] (8,3) to[line to] (10,3) to[line to] (10,0) to[line to] (8,0) to[line to] (8,1) to[line to] (2,1) to[line to] (2,0) to[line to] (0,0);
\node (Anode) at (-0.8,0.3) {Anode};
\node (Cathode) at (11,0.3) {Cathode};
\draw[line width=1pt] (1,0) to[line to] (1,-0.5)  to[line to] (4.7,-0.5);
\draw[line width=1pt] (5.3,-0.5) to[line to] (9,-0.5) to[line to] (9,0);
\draw[line width=1pt] (4.7,-1)  to[line to] (4.7,0);
\draw[line width=1pt] (5.3,-0.7) to[line to] (5.3,-0.3);
\fill[black!20!white] (0,0)  to[line to] (0,4.5) to[line to] (2,4.5) to[line to] (2,2) to[line to] (4,2) to[line to] (4,5) to[line to] (6,5) to[line to] (6,2) to[line to] (8,2) to[line to] (8,3) to[line to] (10,3) to[line to] (10,0) to[line to] (8,0) to[line to] (8,1) to[line to] (2,1) to[line to] (2,0) to[line to] (0,0);
\fill[black!100!white] (0.875,0) rectangle (1.125,0.7);
\fill[black!100!white] (8.875,0) rectangle (9.125,0.7);
\draw[line width=1pt] (0,0) to[line to] (0,6) to[line to] (2,6) to[line to] (2,2) to[line to] (4,2) to[line to] (4,7) to[line to] (6,7) to[line to] (6,2) to[line to] (8,2) to[line to] (8,6) to[line to] (10,6) to[line to] (10,0) to[line to] (8,0) to[line to] (8,1) to[line to] (2,1) to[line to] (2,0) to[line to] (0,0);
\end{tikzpicture}

Which yields this:

Answer 1

To answer your question: No, there is not an easy way to draw this, other than to try some vectorisation on the .png (e.g. with Autotracer.org). Fortunately, some of us don't have anything better to do :)

Edit
Fixed the left and right tubes, noticed that they are supposed to be open at the top.

Edit 2
I wanted to draw the pattern of the acidulated water too, so now the image is complete :) . Of course you can choose for yourself which one you like better, I just wanted to give you that choice.
