I got some really discounted rosin and I was looking to convert a gram or two of it into cartridges. I’ve been reading that most people use a glass syringe to fill them but I was reading another thread that you just go to your local pharmacy and get a normal plastic syringe. Anybody have any advice or experience?
I tried doing this and had no luck at all.
I used a blunt syringe specifically made for this purpose, but the fluid was too viscous to move with it.
I think you may have to get a hot plate or something to warm it up and soften it before the syringe would be effective. I just gave up on the idea after my first few attempts, but good luck to you.
Yeah I watched a video that just popped a jar of it in an oven set at like 150 maybe but it was for 24-48 hours which sees like a lot
You need to decarb the rosin, which is why it says heat for 24-48 hours. It didn’t take that long when I did.
I use a mug warmer, and after its decarbed you can inject it immediately or let it cool and warm it back up a hair to make it less viscose.

They say glass, because you CAN melt the plastic if the oil is too hot.
For fountain pen cartridge refills I got what are called blunt syringes. Like a syringe but the tip isn’t sharp at all. I imagine you want the same thing.
Why a glass syringe and not a normal plastic one?
I was thinking glass because of the warm/hot liquid that would be inside of it but these could work
Handling straight rosin is nightmarish. You couldfreeze it so it solidifies and try to get chunks in the cart? I never was able to get reclaim rosin out of my hoohah tubes without a big mess/headache.
I only ever syringed activated rosin cooked into coconut oil for pill cap edibles. Syringing regular rosin would be awful.
I understand the appeal of pens and carts but like maybe just get a vaporizer thats actually meant for concentrates if you want to go that route. Its the easiest thing in the world to heat a DV tip and then lay some concentrate on the inner walls and heat it back up. Or get some vape wool and saturate it with oil and load it in the tip.
