Dabtown’s Distillate Hack #1: Empty Receivers of Cannabinoids Using a Microwave

by Luke on December 20, 2018

Before you learn how to empty receivers of cannabinoids using a microwave, please be advised there are several ways this can go wrong. This blog post does not purport to address all the possible safety concerns. Please consult your safety officer for full professional guidance.

High-purity THC/CBD distillate will be very viscous. If it is cold enough, it will become a glassy solid that does not flow. In order to empty the receivers often, you will need a way to heat the distillate just enough so that it can be poured without overheating.

The receivers are full of ~90% cannabinoids and in the presence of oxygen and heat, they can potentially degrade. Here are some tricks from Dabtown Dylan of Lucid Oils.


A microwave is an inexpensive way to carefully and homogeneously add heat. Microwaves are able to penetrate the whole sample evenly and the glass is not being directly heated.*

There is still the possibility of overheating the THC/CBD distillate, so Dabtown doesn’t heat for more than 30 seconds at a time and no more than 45 seconds total.

*Microwave ovens should be for lab use only and never used to heat food or drink. We are also pretty sure that operating a microwave on its side is not part of any lab’s best practices policy. Read and follow your microwave oven’s instructions.

Emptying the Receiver

Whether you are preparing for a second pass or just need to fill some vape cartridges, getting your distillate out is the priority. Be careful not to pour the distillate out all at once. It can form a large glob that can quickly overwhelm the mouth of whatever containing you are using.

  • When I put my distillate in vegetable oil and mix it up, do I need to put the oil/distillate mix in the microwave and heat it or is it ready to go?

  • I have a liter of distillate and I’m trying to make carts. What is the best way to heat up a whole liter of distillate?

    • Vacuum ovens work great as they will help pull air bubbles out of your oil from pouring. A double boiler if you are really worrried about heat or just a heat gun and some patience work too.

      As always, be careful about heating glass directly! Cracking a mason jar into a couple gallons of water makes for a much longer day!


      • How long should I keep the distillate in the double boiler? and what setting on my stove should I use? because I don’t have a hot plate stirrer or a vacuum oven. I plan on investing in one of those products in the future.

      • if i use a heat gun on a mason jar will it directly heat the glass and break it?

    • Double boiler technique

  • After filling your carts with the distillate and terps mixed. how long should I wait before testing out the quality of the cart?

    • I like to wait until I see the level drop slightly. As it absorbs into the wick/coil, the level should go down slightly.

  • What would happen if I cooked dabs in the oven

    • It would probably melt, decarb, and lose some terpenes/flavor. THC will be fine for the most part though. Don’t use too much heat.

  • I have an oz in a pyrex. Is it better to microwave or put it on the hotplate?

  • can u heat it in a silicone container

    • I don’t know if they are microwave safe or if they are safe as the material warms.

      If you need to get it out of a silicone container, I would just try to use a hair dryer or something.

  • I work with cbd at work making tinctures creams ect. and we sometimes have to wait a long time before we can start you think the microwave can speed up the process?

  • How can someone test THCA diamonds to see if it is real? They have videos showing supposedly what fake ones do, but nothing to show how the legit ones burn.

  • Accidentally mixed vegetable oil in with my shatter,how can I separate them

  • Hi I have about half pound of honey oil in Mason jar and its very very sticky. I need to extract and put into vials. What is the best way possible?

    • Look up double boiler. Loosen the lid as to not let pressure build. But leave the lid on to keep moisture out.

      Heat guns work well too. Hair dryers might work but will take a while.

      Get the oil and the container hot and it will pour out. Best to rig up something to hold it upside down at an angle.


  • I let the container sit in steaming hot water until it melts.

  • Can I use coconut oil or evoo to thin out my concentrate to more of a liquid to use in vape pens?

  • I have a 100 grams of distillate. I usually use one gram at a time. How many times can I heat up the container to remove a gram before I start degrading it?

    • Good question. 100 times would be a lot, so probably before then. It depends a lot on how hot and for how long it stays hot. Also, the amount of air exposure.

      If I had to guess, 20-30? No data though. My advice is as few as possible.


  • I have 500 mg of distillate that came in a big jar. I guess I have the option of getting a tool to scoop out small amounts of the oil while solid and just heating up that oil that was scooped out my jar to avoid repeated heating of the main source. I’m just curious, has anyone used an instant pot or crockpot to warm up large quantities of distillate?

  • I have a distillate dart, MCT oil and a magnetic stirrer (that does not tell me it’s heat level.) Just that it’s on. My question is: how long do I heat the combination of oil & distillate, and how much longer should I let it stir/mix for?
