The command is as follows: \flask[ <arrow direction> ]{ <position of the flask> }{ <pressure> }{ ...

You know how to use coordinates. So you could just say \draw[thick] (C1.east) -- ++(1,1) coordinate (y) -- (y |- C2.south);. I left the red line in the code as thin and dashed for comparison. \documentclass[border=3mm]{standalone} \usepackage{tikz} \usetikzlibrary{calc} \begin{document} \begin{tikzpicture}[font=\sffamily] \node[draw, circle](C1) at ...
