What's the difference between the 10k rotovap and the 2k one? It seems like pound for pound (of dry ice that is) the 2k one might be better for smaller volumes.

What's the difference between the 10k rotovap and the 2k one? It seems like pound for pound (of dry ice that is) the 2k one might be better for smaller volumes... unless you're trying to simulate martian polar ice caps in your back garden...
FWIW I want one of these: http://www.amazon.co.uk/Nauticalia-Copper-Pot-Still/dp/B00491YMPU/ http://www.amazon.co.uk/Nauticalia-Copper-Pot-Still/dp/B0049...
I'm trying to convince the wife that a 'purely ornamental' (due to UK legislation) still used in a 'demonstrative manner' should fit in a small two bedroom starter house. Somehow the fact that I don't want to cook meth in the house after seeing breaking bad seems to count against me with her...
- tptacek 16y agoWhere's the $2k rotovap? The $10k looks like an R-210, which is the one I keep seeing in demos.
- dunham 16y agoI think he means the $3k one, it's listed as a "related product" on the page of the $10k one: http://www.amazon.com/Cole-Parmer-Rotary-Evaporator-System-Vertical/dp/B003NV4W02 http://www.amazon.com/Cole-Parmer-Rotary-Evaporator-System-V... Looks like smaller "bath capacity" and smaller temperature range (5C-90C)
- tptacek 16y agoIt looks like this guy don't apply vacuum pressure (the Q&A on their site suggests that you can plug it into a separate vacuum pump). That's pretty key, since the reason to own these things is vacuum distillation.
