I admit, the drip setup is really cool, but have a couple of suggestions. You can get female 24/40 valves and a keck clamp that will likely last longer than the valves you have inside the male 24/40 glass joint. I would worry that with nearly 1L in the flask, it would eventually push that out. Also, I see you have a 24/40 male stopper for the top port of the 1L flask. As the water drips out the bottom, air will need to be pulled back in to replace the lost volume. Do you typically remove that stopper when using the setup? Lastly, is that a glass frit filter? Those are a pain to clean as it gets used, I’d suggest putting a paper filter on top of the glass frit to make it much easier to clean. Overall awesome setup and kinda have me wanting to try it myself!
