I think I need some distilling (boiling) and collection flasks and a 3-way adapter with a thermometer. I was thinking of using an open vacuum adaptor to join the lower end of the condenser to the receiving flask. Does this sound ok? And if so, what kind of condenser should I use?
That sounds good. Here's a drawing of the set up. I'd use a water-cooled condenser.
That sounds fine. You only need the open vacuum adaptor if you're using a sealed distillation setup and you have cause to worry about the pressure while distilling.
I use a basic distillation apparatus with a Graham condenser and a Kjeldahl distillation bulb. Currently, I skip the three-way adapter with the thermometer because I'm just doing basic distillations and while I can seal mine I generally don't because I'm not worried about my distillate evaporating .
