I too am looking for a 2 stage pump... I'll check out what HighBurn posted but are there more options out there people feel comfy recommending?
We don't however cold boil with them without a cold trap, as the solvent dillutes their crankcase lubricant, but use a military surplus MASH rotary vane pump instead, which has sealed bearings.
.
What does "cold boil" mean? can you elaborate on this a little bit or send me to a thread that explains all this in detail? I feal like everyone speakin a different language... Hopefully Ill be an expert soon.
I went ahead and got the fjc 3.0 cfm because a friend had a good deal on it, now I need whatever components in order to get ta purgin. do I just need a hose and a suction cup or is it a lot more to it?
Thanks yall for the help. much appreciated!
You can either buy or build a chamber and adapter.
I was curious what difference does the size in chamber make, 5 G versus more. Does it make a difference in the vacuum power required, or does it just relate to the amount of material you wish to process.

This one looks cool, but it got a black bottom I dont know if its rubber or what, I need one that can be heated up...[/url]
Its not a good idea to heat up a vacuum chamber from the outside, I've read about numerous implosions happening because people thought they could heat their ebay bought dessicators from the outside. There are a few that have managed to be fine but its definitely a risk.
If you want to keep a certain temperature use a ceramic plate that you heat in the oven before placing in the dessicator.
