How to make Solventless Cartridges – Lowtemp Industries

We’ve been asked daily “How do I make Rosin Vape Cartridges?” for years now! So we linked up with Infinite Melts during a day of their rosin cartridge production to show you guys how it’s done!

– Step 1: Fill your jar with rosin! Hash rosin will absolutely perform much better than flower rosin. We recommend to not fill the jar over the halfway mark to allow for headspace in the jar. This prevents any over flowing/boiling of oil from the jar.
– Step 2: Pre heat your oven to 150f. Yes, you can use a vacuum oven, but it’s not necessary. The more accurate your oven, the better.
– Step 3: Place your sealed jar into the oven for 24-48 hours. Sometimes it can take a little bit longer, depending on how much material there is and how stable the material was to begin with. DO NOT OPEN UNTIL YOU ARE READY TO FILL YOUR CARTS! Every time you open a hot jar of hash, you’re releasing volatile terpenes.
– Step 4: Pull your jar when you have a water like viscosity with very few rising bubbles. If you have more bubbles than what’s shown in this video, put it back in the oven. Put your glass syringe in the oven to keep it warm.
– Step 5: Fill your warm glass syringe with the decarbed Rosin.
– Step 6: Flip it vertically, and slowly insert and pull the syringe in and out. This will “smash” the bubbles on the top layer of the oil.
– Step 7: Fill your cartridges! Don’t worry about filling the bottom of the cartridge, we’ll wick them in a moment.
– Step 8: Wick your cartridges! Lower the temperature in your oven to about 100f. Put the cartridges in the oven for about 5 minutes. This melts the oil down into the cartridge, and soaks the wick for enjoyable first hits. (We do not recommend putting foam in the oven, however this polystyrene is safe up to over 400f/204c).
– Step 9: Top off each cartridge again with your syringe. Do not overfill.
– Step 10: Cap your cartridge and enjoy!

Some additional considerations:
– This is one method of creating Solventless cartridges. There is an additional method that involves the mechanical separations of terpene fractions and THCA isolation. This process involves a bit more technical of a process and yields a lot less for your starting material. If you’d like for us to put out a video on this process, please comment below!
– There are many ways to fill your cartridges. Depending on the scale of your production, it could be an automated machine or varying sizes of glass syringe. They even make syringes with heating elements attached! Precise dosing syringes are helpful and convenient for regulated markets that require it.
– If exact weights need to be dispensed, we would recommend dispensing on a scale. Or even better yet, measure weight per ml and utilize a precise dosing syringe.
– If manufacturing for production, choose your carts wisely! This is hardware you are choosing to stand behind as a producer. Some cart manufacturers have very high failure rates, which can hurt your company’s brand reputation. Not too mention the cost associated with replacing these products for your customers.

    1:24 it looks like he sucking it out his finger 🤣



  2. @mattygilbert5693 on March 4, 2024 at 7:25 am

    The rosin never hardens back up?



  3. @JackWilly-ui5gc on March 4, 2024 at 7:25 am

    Will the 150 decarb the rosin im new to this but i press my own rosin



  4. @kylinaustin7596 on March 4, 2024 at 7:26 am

    How much did u use of product ?



  5. @johnnysk8s on March 4, 2024 at 7:26 am

    Why doesn’t the oil solidify in the cart once it cools?



  6. @BlazedReefer on March 4, 2024 at 7:26 am

    Where do you get your custom carts from they look dope!



  7. @pyrogee33 on March 4, 2024 at 7:27 am

    What manufacturer do you recommend for empty cartridges?



  8. @RosinDaddy5280 on March 4, 2024 at 7:27 am

    I love that you guys are in my back yard
    Arvada co ✌️❤



  9. @Hopeinformer on March 4, 2024 at 7:30 am

    Where do they carry their empty cartridges?



  10. @DarkSparkCannabis on March 4, 2024 at 7:32 am

    How does this process work/why doesn’t it harden back up?
    Will this work with bho wax or just rosin?



  11. @user-sk6dh1kf2x on March 4, 2024 at 7:32 am

    Hi LowTemp, amazing video. I start exploring making my own 510s now to keep the quality high and price low. My question is, modt rosin i buy has big terp pools on top or around the container. Should i separate the terps and decarb the rest, adding the terp sauce later before injecting to my cart? What happens if i decarb the terps also, will i lose all flavors? Thanks.



  12. @OakhengeHempFarms on March 4, 2024 at 7:32 am

    Beautifully done gentlemen



  13. @whocares8735 on March 4, 2024 at 7:34 am

    The only reason the concentrate exists to begin with is because the weed is probabaly covered in powdery mildew.



  14. @miguelribeiro9315 on March 4, 2024 at 7:34 am

    Great video guys!!!! Why does it have to stay 24 to 48 in the hoven? Thank you in advance ❤



  15. @user-ud4fi8np9d on March 4, 2024 at 7:36 am

    Bubbles💦💧



  16. @abcplay9978 on March 4, 2024 at 7:37 am

    Se puede hacer con hachis?



  17. @alecspaude1211 on March 4, 2024 at 7:38 am

    Won’t the terpenes and flavor get ruined if it’s sitting at 150 degrees for too long? There’s been times where I’ve hit a rosin cart and the taste was bland af. I’m working on making my own right now, any advice from someone that’s experienced is appreciated! Lmk



  18. @aaroncao4820 on March 4, 2024 at 7:39 am

    But I think my filling gun will be more useful, with high accuracy, constant temperature heating and heat preservation.



  19. @Htxrdz on March 4, 2024 at 7:40 am

    Just made my own and man i tell you they did not disappoint ill definitely be taking this route instead of buying carts now❗️🤷🏽‍♂️



  20. @karnivorouskirby2062 on March 4, 2024 at 7:42 am

    Where do you get that syringe???



  21. @darkstar3246 on March 4, 2024 at 7:42 am

    i cant move at the sight of the sheer beauty



  22. @Site---Legalthccartstore on March 4, 2024 at 7:43 am

    In our culture, the Native Americans, when two strangers come together. You know what we do in our culture? We smoke the peace pipe.



  23. @lilgato512 on March 4, 2024 at 7:46 am

    Ceramic atomizers very nice!



  24. @jamesfrazier2813 on March 4, 2024 at 7:47 am

    Decarb



  25. @BiodigitalStuff on March 4, 2024 at 7:48 am

    I feel like some things might have been left out. My rosen thickens too much and won’t work in a cotton based atomizer. I believe there was some post-production to the rosen before making the cart to remove the fats. The liquid is too clear and too thin. I don’t see how simply heating it changes that. But i’m no expert and I’ll give it a try.



  26. @CodyChristensen10127 on March 4, 2024 at 7:48 am

    After this decarbonation process does this make the rosin less potent?



  27. @bravadoplayz630 on March 4, 2024 at 7:49 am

    so the 24-48hr in the oven was the decarb? Just as some do by putting it on a hotplate and letting it boil for an hour or sum like that? cuz if this wasnt the decarb it would crystalize in the carts.



  28. @jonnn420 on March 4, 2024 at 7:50 am

    Don’t you have to add terpenes?? Or is that not required? Because I looked it up and it says adding terpenes is what makes it smoke properly in the cartridge.



  29. @evelynarellano5979 on March 4, 2024 at 7:52 am

    Yo how can i try your carts from cali currently smoking highland rosin carts 🔥



  30. @drewmartin7800 on March 4, 2024 at 7:53 am

    Is there a smell associated with the heating process?



  31. @jaymartinson3236 on March 4, 2024 at 7:53 am

    bro just pumped half that syringe into his finger 👀



  32. @Kayh1979 on March 4, 2024 at 7:54 am

    Why does it have to be in the oven for 48 hours? The rosin is much faster liquid. Why do the bubbles rise? Somehow I don’t quite get it



  33. @jasonknight5045 on March 4, 2024 at 7:55 am

    fn noice, the real deal, thank you



  34. @ItAllAddsUp963 on March 4, 2024 at 7:55 am

    Thank you. ❤❤



  35. @yep5689 on March 4, 2024 at 7:56 am

    Damn I wish you could make some presses that a common working man could buy I mean damn I have kids and I can’t even afford gas much less a 300 dollar press or oven or anything else like that I mean come on guys target the working class people not people like bill gates



  36. @lisa-mareelyons8135 on March 4, 2024 at 7:58 am

    Can i order a pod , ?



  37. @RockingherAllnight on March 4, 2024 at 8:01 am

    Why does the rosin need to be decarbed?



  38. @teddy.ruxpin-pimps-hoes on March 4, 2024 at 8:02 am

    .



  39. @docsullen2612 on March 4, 2024 at 8:03 am

    Wont the liquid just turn solid again when it cools down?



  40. @OhhGeee on March 4, 2024 at 8:04 am

    What state are these available in?



  41. @roberttaggart5757 on March 4, 2024 at 8:05 am

    Can this be done with flower rosin?



  42. @MrKawasakirider10 on March 4, 2024 at 8:06 am

    Where do you get the cartridge from?



  43. @gwenbernal-fc2ei on March 4, 2024 at 8:08 am

    💜💜💕💜💜



  44. @RandyRhoadsFL on March 4, 2024 at 8:09 am

    dope video



  45. @jimmyjackson7134 on March 4, 2024 at 8:09 am

    Where you able to run that thing the whole 24 or 48 hours? Makes me worried of a fire hazard, is there anything wrong with heating it for 4 hours then letting it cool and repeat so the oven don’t ignite or does that mess up the product



  46. @jimmyjackson7134 on March 4, 2024 at 8:10 am

    What model is that oven, I’ve been trying to find one similar



  47. @user-ud4fi8np9d on March 4, 2024 at 8:11 am

    Filled to the brim



  48. @tylerfosse7336 on March 4, 2024 at 8:13 am

    Maaaaaan why was your video SO much more informative and str8 to the point than any other ive seen? Only question i have is if i want to add some liquid terps at what point do i add them? I assume that would be the last step before adding to carts? Add to your rosin once its reached the viscosity youre after? Or with the air tight seal is it ok to add it at the beginning? Ive had luck filling carts just by cutting my rosin with terp or a liquidizer, but thjs looks much more promising.



  49. @user-di6wk2id6z on March 4, 2024 at 8:17 am

    Where can I get your refillable carts and the glass syringe?



  50. @Kc7kid8 on March 4, 2024 at 8:20 am

    Hey on time do you base on weight you are putting in or just a average 24 48??? Not trying to do a large batch just enough for a weekend of stupidity for a old man lol😂
