OK.....so far so good. So, is there a specified amount of EC to have contained? If so, how do you plan on keeping such a volatile substance contained to prevent evaporation loss? Keeping it (along with the entire bellows assembly) below it's vaporization temperature? And at the same time, solder closed the service port? I know at room temperature, soldering hollow objects can be tricky. For example, something as simple as a brass carburetor float tends to suck the solder in as the air inside cools enough to change the internal pressure and draw the solder in before it solidifies. The only trick I know of for that is to keep the entire float near or slightly above the solder melting point. Or is there a sealant of some sort other than soft solder than can be used?
