You can pick up 10 .45um syringe filters with 10ml syringes off Amazon for under $30: http://www.amazon.com/dp/B005HR3TK4/ref=cm_sw_su_dp When I winterize, I usually keep it in the deep freeze over night. I've used both 99% ISO and Everclear... both work. After it's been in the deep freeze...

I haven't tried the beaker liners yet, but they are on my list. So far I have tried: PTFE Evaporation Dish: http://www.amazon.com/Chemware-D1069044-PTFE-100mL-Evaporating/dp/B002TG3WJE PTFE Petri dish liner:http://www.fluorolab.com/140mmteflonpetridishliner.aspx PFA Petri Dish...

No offense taken. It's all good :) I think we are on a quest for the same thing, just coming at it from different places. I started out spraying into glass and then scrapping that up into smaller glass to vacuum, and quickly started looking for a better solution. I tried parchment paper and...

^^ the point being is that the coating isn't stable or well applied. If it can come off during a mild scrap with a razor, it could come off other ways as well. If you want to be dismissive and laugh off getting contaminates in your oil, that's certainly your choice.

I picked up one of those black mats a few weeks ago (http://www.amazon.com/gp/product/B0000CFG5F/ref=oh_details_o03_s00_i02), and decided against using it. The problem is that if you take a razor and scrap the surface of the mat (like you would after spraying), you'll see black flecks on the...

I'm experimenting with using d-limonine for a variety of different things, but I have not tried using it as part of a BHO tech. The reason I haven't used it, is that I can't figure out how to purge it from the oil. the boiling point of d-limonine is higher than that of THC so heat purging is...

There is some debate on this topic and definitely different opinions. I would say that most of the best oil makers I know pack whole buds or popcorn size nugs and they pack them very tightly. When I do a run that is 8g or more, I'll generally pack whole bud or popcorn size nugs, but I...

You might want to check this out. Very similar discussion: http://fuckcombustion.com/threads/d-limonene-and-extracting.6392/ I purchased a gallon of the food grade d-limonene a month ago and have been experimenting with it, but I haven't used it as part of my BHO tech.

I use a Bel-Art model 420430000 and a JFC 6905 vacuum pump. The chamber is plastic and I would definitely not heat it.... instead, I keep several ceramic tiles warmed to 150f and place the tile in the chamber and then set my oil on the tile. I've noticed that any time I winterize my oil that...

That should work. If you can get your hands on some 190 proof Everclear or 95% ethanol, you can use that too.

You can refine it even further by taking the budder that you disolved in ISO and putting it in the freezer for at least 4 hours, and then running it through a coffee filter. Putting the ISO mixture in the freezer will cause any remaining plant waxes to coagulate and solidify making them easy to...

Different components in the concentrate will start boiling/evaporating at different temperatures. Personally, I'd start with temps between 375f-450f. Here is a partial list of the active components in cannabis and their respective boiling points...

^^ it doesn't mater if it's Ti or glass. It's just about exposing the BHO to something hot enough to cause any residual butane to combust. Based on your results, it doesn't sound like the bad taste isn't butane. Hard to say if winterizing would improve the taste, but it might be worth a try.

Sorry your vapercone isn't working out. I don't know anything about MedStick, but after a quick look at their website I would suspect it's just another reseller of cheap overseas units that mostly don't work. I base this guess on the fact that the vapecone product page gives a 404 error, and the...

Drop a small dab on some hot Ti... if it sparks and sputters then it's not fully purged. I'm a big fan of vacuum purging, but I wouldn't personally use a mason jar. They are not designed to withstand a vacuum and can implode. (I'm really big on safety when it comes to BHO)

I find the quality of the product is extremely important, but I am always happy when I find a great deal on some mid grade as it gives me a chance to experiment on material that won't make me cry if it doesn't work out :)

Winterization isn't a solution for underpurged oil. If it's underpurged, I would gently warm the oil and purge it some more (vac it if you can). I've winterized oil several times to remove impurities, mostly to clean up oil that buddered, and I've been very happy with the results.

Sadly the president has lied to us about this before: http://justsaynow.firedoglake.com/2012/04/25/obama-lies-about-federal-marijuana-law-to-rolling-stone/ Given his lies on the subject, I'm not going to waste my time hoping he is telling us the truth this time... but with that said, maybe he'll...

I still have it, but it's retired. I upgraded to a Thermovape instead of getting the Omicron V2. Even though I didn't go with the Omicron a 2nd time, Delta9 products remain on my short list.

I'd take a look at the products from Delta9 and Thermovape. Both are US based companies that have a very solid reputation here on FC, and both make excellent portable oil vapes.
