DIY $100 rotovap

Looking to remove low boiling organic chemicals on the cheap? Here’s how, Dylan writes – “Take a stroll through our labs and you will notice a curious number of black Crock Pots serving as water baths for the rotovaps. They cost $20 and came from Wal Mart. When I first joined I thought this was a little ghetto-tastic, but having used the Crock Pots for a number of years now I can say they are perfectly fine. Why spend $1,000 on the fancy VWR digitally-controlled contraptions when a $20 solution works the same? Especially since we have 20-odd rotovaps, stuff like that adds up real fast.” – Link.
