Ah OK, so a little frozen CO2 in the yield is typical? Thanks for your insight, we're getting results similar to your picture, so I guess we're on the right track, I just wasn't expecting it because I hadn't seen anything like that prior and was alarmed to see a frozen solid block like that. Given the amount its mass dropped when we let it thaw, I was worried we were trapping and losing too much CO2.
What's the best way to get all that residual water vapor out of that? We've been using a vac oven, but it's been taking a lot longer than we'd hoped. Any alternatives? Rotovap?
Vac oven, Rotovap. or just warm it up in the oven without vac, then suck them out with a syringe with dispensing needle also works. The water should separate after some time once warm making it easier to deal with. You could also leave out @ room temp and after many days the water would evap off...but not very productive.
