    Completely dissolving a gas into a liquid

    Hmmm, then what would be the best way to maximize the amount dissolved? I was thinking, if I added a 1 way valve into the system, then it would draw in air consistently as long as the system isnt at atmosphere. So if anything happened where the pressure of the soda wasn't at atmosphere, the 1...

    Completely dissolving a gas into a liquid

    Ok, I'll try to clarify. (see attached pic) Let's say I want to re-carbonate soda that's gone flat. I would put soda in a vessel which will allow CO2 to pass through it. And then the CO2 just flows through the soda again and again until its dissolved as much as possible. If I cool down the...

    Completely dissolving a gas into a liquid

    Hello PF I want to dissolve a gas in a liquid. I figured I could create a closed loop vacuum system. I introduce gas into the lines at atmospheric pressure, and then close off the lines, so the intake and exhaust of the vacuum pump are connected. Then I turn the pump on and the gas just...

    What would cause sudden change in evaporation chamber behavior?

    I actually figured out the problem. The electrodes were too tight when securing the evaporator boat. I don't know why this happens, I'd figure better electrical contact would mean better performance, but no. I loosened them significantly to the point where I can still shimmy the boat around...

    What would cause sudden change in evaporation chamber behavior?

    Hello all, I use an evaporation chamber at my lab every day. Basically, put some substance in the chamber, close it, bring it down to vacuum, and pump enough current through it to vaporize it where it deposits on a substrate. I've been using 175A to create a deposition rate of about 1...
