    Looking for CO2 diffuser for lab experiment

    Had to look this up on google, very useful, but at the same time was a little disappointed with the images presented haha ;) ;) Tried the water bath idea and managed to get the solution inside the glass vessel to 50 degrees C. I'm sure with a little more time it will reach 60 degrees! :clap...

    Looking for CO2 diffuser for lab experiment

    Hi guys back again, I am going to do the experiment in a large glass vessel that I found laying around in our lab. The vessel has a really thick glass bottom: I need to heat the solution inside to 60 deg C. I tried to do this with a heating plate at 60 deg C but the glass is very thick and...

    Looking for CO2 diffuser for lab experiment

    Okay, I need to make some saturated calcium carbonate solution because we are studying scaling effects. So I need a solution so we can apply to a heated metal surface (~120 degrees C) to form scales on the surface. According to Wiki the solubility of calcium bicarbonate is 16.6 g/100 mL (20...

    Looking for CO2 diffuser for lab experiment

    Also, I have never used CO2 before. In my case it will be to lower the pH of the water by "several pH units" (this is what the paper I am reading says), so that I can dissolve calcium carbonate into the solution. In your guys' experience does a decrease in pH with CO2 occur rapidly? (my "tank"...

    Looking for CO2 diffuser for lab experiment

    Apologies for the delay. Awesome, thank you for the suggestions they are very much appreciated! I had not realised there were glass CO2 / acrylic diffusers out there, this may certainly solve our problem. The toothpick, very imaginative! And the DIY option is something I am presently working...

    Looking for CO2 diffuser for lab experiment

    Hi, I am a scientist and stumbled upon your website whilst looking for a CO2 diffuser. It seems you guys know more about this than the guys in our chemistry department! So was hoping you may be able to help. Anyway, I wont bore you with the details but I need a good way of getting CO2 into...
