However, since our reactor is fairly small, a 100mm pipe seems excessive, especially since we will be having two. \r\nThe texts also suggest attaching a nozzle at the bottom end of the pipe to constrict the diameter to about 45mm in order to prevent deposition. Taking this into account, would it be feasible to reduce our overall pipe diameter to about 50mm and have some sort of funnel structure at the top to provide a large enough surface area for trapped air to escape?\r\n\r\n@zoemaisel @JenniferKJackson"}}
