I had the same concern a while ago so I asked a PhD in materials science to which he replied

I have one and it's quite useless for this purpose. The flat surface makes poor contact with your most likely concave bottom chamber. If you want something that actually works and works well, nothing beats a flexible heating mat on top of a towel so that it can make full contact with your...

Since we're talking about microwaves, here is a microwave used in oil making http://www.milestonesci.com/neos-gr.html

+1 for sanitary tubes, here is handy calculator that lets you know how much butane you can expect to use and how much weight it should hold http://terpenator.info/calculator.php

I've done flower runs that yielded ~20% and after winterizing lost up to %50 of that. Butane being non-polar takes the waxes along for the ride, IPA being polar doesn't. I'm guessing this has something to do with the yield. Now I'm curious what the highest yield possible is with QWISO and how it...

9% yield on flowers is a good thing? :uhoh:

Material destined for extracts are usually harvested after 45 days, rather than 60 or longer for flowers. Maximum terpene content with zero degradation (conversion to CBN due to decarboxylation). That's one of the differences between light colored dispensary supplied oil from legitimate...

The oil should be spread as thin as possible when purging. If you hold the parchment up to the light and see any cloudy spots it needs further purging. The picture you posted looks like too much heat was used and the terps are all gone. What brand of butane are you using for the extractions...

iso+salt is all I need, then again I don't combust.

Cool, that's the vape they used for this study http://www.cannabis-med.org/data/pdf/2001-03-04-9.pdf where they noted that any temp above 200c is gonna give of benzene, toluene and naphthalene, and that temps of 185c or below give off none of those carcinogens.

If the oil is not winterized it contains epicuticular plant waxes. Waxes are not readily absorbed by the skin as the molecule is too large. That means it's either staying in your lungs where you would notice reduced lung capacity over prolonged use (most likely false), or your coughing it up as...

I'm thinking a bottom feed atomizer (air comes up through the 510 connector) with a stove top coil with screen on top might work to for dry herb on a rebuilable, if this vape is any indication.

You guys sure are adventurous funding some guys dream of owning a vape manufacturing company. Personally I prefer to purchase products that are tested/reviewed as well as available at time of purchase. Paying for something that is neither tested nor available seems like a generally bad idea.

Very nice setup @DieHard you went all out with the PID, I would recommend replacing the water in your larger pot with sand you can pickup at the local hardware for $5. It holds and distributes the heat perfectly and never evaporates or causes moisture around your product. Also it looks like you...

The SSR (amico 25a) on my DIY enail burned out from being on 24/7. I ordered a replacement for $4 and it's good as new. User servicable is good, having to ship international for warranty servicing is bad.

Getting an accurate reading across all the different types of metals/materials using an IR thermometer requires one with adjustable emissivity setting and those are expensive. A type k thermometer with wire bead probe is $20 and will give accurate readings across any material. Finding the...

3M = nextel = xc-116 Lance from steammonkey dot com posted a while back as he was trying to become a supplier for it http://www.reddit.com/r/electronic_cigarette/comments/1epnbj/monkey_university_5202013_wicks_201/ Here is the relevant quote Looking at rbasupplies they appear to understand the...

Sweet dripper, I was using a normal one with just the topcap before and I found it got sticky/messy after a while around the orings making it difficult to remove the topcap. I figured a 3 piece dripper like the one your using would make it less messy, although ideally the topcap sits on the...

you have several options - use a 510 to 510 adapter so worst case would be messing up the adapter instead of the battery - realize these batteries are cheap and get backups of your backups.. - use something with a higher build quality, like a mechanical mod, (with replaceable topcaps if you...

DIY enail is great if you enjoy cutting down on consumable items like butane. It also makes it way easier to do low temp/carb capped dabs, since you can dial in and hold the exact temp you wish.
