Stuff you'll need (Prime links given)

$200 digital hotplate: amzn.com/B00AYGIFCA

$13.50 large flask: amzn.com/B00BERGESK

$9 rubber stopper to fit flask: amzn.com/B00ES3UE9C (can be had for $.50 at Fred Meyers or lab stores)

$17.49 for a hose to run from faucet to condenser: amzn.com/B000KI7VN6

$16.72 for the condenser: amzn.com/1450567898

$13.03 for a stand to hold the condenser: amzn.com/B00657N7TS

Misc you likely already have around:

Large pot or dish that can hold the flask

Cleaning sponge or rag

1/2 gallon vegetable oil

Total cost: $269.74 and maybe $20 for the misc stuff if you lack it

Preparation: This needs to be done in a temperature controlled room; the method uses slight variations in temperature to isolate out the individual chemicals, so any fluctuation in the room will hinder this. You will need to be near a sink with a running faucet. Be prepared for this method to take 24 plus hours.

Method:

1. Place your large pot on top of the hot plate, and place your sponge or rag in the center of the pot. This will prevent a hot spot where the flask touches the pan.
   
   
2. Fill your flask with the herb or extract you will be isolating (use extract, the results are much purer!), and place it on the sponge in the pot. Stopper the flask.
   
   
3. Attach a hose from the stopper to the top of the condenser. Attach a hose from the faucet to the coolant intake on the condenser. Attach a hose from the coolant exhaust and let it dangle in your sink.
   
   
4. Fill the pan with 1-2 inches of oil. Not enough for the flask to float, but enough for the oil level to be above the level of your herb or extract in the flask.
   
   
5. Start running cold water through the condenser, and start heating the oil. To get a list of the required temps, lookup each cannabinoid on Chemblink (or wikipedia), and look for the evaporation temp listed. Start with the lowest temp and work your way up.
   
   
6. Once the oil has reached the temp you specified, let the system run for at least 4 hours. You will begin to see resin buildup inside of the condenser. This is your isolate. Once you are satisfied that no more isolate is building up: run hot water through the condenser so the isolate melts and runs out of the condenser.
   
   
7. Go up a heat level and repeat 5-6.
   
   As I said, this really only works for THC-like cannabinoids, you won't get any terps with this method without much more expensive equipment (theyll just evaporate away), and the overall loss is great enough that its unlikely youll be able to get an isolate of CBG or THCV, since they are such a small percentage of the cannabinoids, but you should have no problem getting pure THC and even CBD, assuming your starter strain has more than a percent of it. Once you have isolates you can isomerize and do other fun stuff as well.
   
   That said, pure THC isnt fun at all, but its a great learning experience, and you can also use the same setup to distill essential oils or liquor, which is a slightly different process but uses the same equipment (though you can sub the digital hotplate for a cheaper electric range for those purposes)

My biggest issue for the longest time was finding the right sizes for what I needed. I finally settled on this: http://www.amazon.com/gp/product/B00BERGESK/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

It's a 1000ml erlenmeyer flask, rubber stopper included. $11.95 with prime.

I definitely needed something big enough to mix in, but also for long term storage, so this works great for me. The stuff I vape needs no steeping time, so I just order specific amounts in the quantity I mix, just dump it all in the bottle, cap it, and mix. Amazon does also have flask sets you can buy if you're looking for more DIY stuff, and I have seen them with stoppers included.

Here are the items that you'll need, it's only like $15 for everything. The idea is basically to boil the flask to vaporize the bud inside and you'll inhale it through the hose. If you want this in your room then you just buy like a $15 hotplate off of amazon, and you can also cook food in there now.

As long as you can drill a little hole and have a stovetop, you're good to go.
