Careful with that. Especially if you have 2mm intake holes. Gets a lil slurpy in the post

air leak somewhere in the gun? that would do it. @tweedledew that sounds interesting. how long does it take?

It’s just a lazy way or warming it up. The bubbles will float to the top and the carts will get unified. Probably 20-30 min or something

I’ve had this happen with co2 oil when using fill temps over 80C. This is decarb. We realized it before we had filled too many carts so I put the oil on the rotovap sans heat and let it rotate under vacuum to remove the CO2. We then resumed filling carts using reduced temps with no issues.
It’s amusing, I’ve always seen people say it’s a requirement to decarb your oil for carts, but personally I’ve never done it. I’ve made 500+ carts for friends and family, never decarbed once. I don’t have the equipment to do color remediation, and people aren’t a fan of super dark oil, so I never decarb. I know I could reintroduce less terps if I was to decarb, as the oil would become thinner, but I only use 6% hemp terps and I’ve never really had an issue. I know my oil decarb’s to a certain extent, considering i vac purge it at 160’f for 5-7 days, but I’ve never fully decarbed any oil I’ve put into carts. I use to purposely use the lowest temps I could, to preserve the natural terps and oil taste. That’s why my friends love my carts, it’s more like smoking dabs then smoking super refined boring ass distillate. Because I don’t decarb my oil, it retains its full cannabinoid profile, so when you smoke you are affected by the synergistic effect of the various cannabinoids, causing the high to be more akin to doing dabs, instead of distillate.
Only reason I got bubbles this time, is because of how hot I ran the reservoir. Regardless, with minimal heat the bubbles settled and the carts work great 
another successful run.

Pretty sure at that temp for that long you’re decarbing a good deal more than you think. 160 for a week is a long time.
Dred did this awhile ago, and it seems all of the thca was converted.

Definitely decarbing @ 160. That happened in a day or so. Or less.

Co2 oil under 50c. Is this decarb? Any agitation would cause this “root beer“ affect.

Looks like its decarbing or more solvent purging

I run my decarbs from 80-110c (CBD). When you heat and agitate that co2 oil and you see small bubbles that is a bi-product of decarbing if you see larger bubbles that may be solvent. Decarb should take about 2 hours at that temp

So, we just experienced this exact same thing. We usually don’t decarb our oil for carts, and we add terps for viscosity. My question… questions… so many…
For those that do decarb, what is your parameters? time and temp?
Do you add your terps afterward, not at all?
Is there any other reason besides this decarbing that would cause what we have…?
Stable in the vessel, stable during injection, and then it’s like air hits it and it starts to bubble… like fizz…
(First time poster here… )
100% decarbing. See how small the bubbles are on the shaft of the cart. That’s not caused by air in the fill.

There’s one other cause for this that’s separate from decarbing or filling temp. I do not know exactly why this happens but this is actually common when certain terpene alcohols are present. The bubbles always dissipate in a day or so but I’ve seen multiple isolates cause this.
If only hemp terpenes were used this would unlikely be the case but I suppose you could just have a unique terpene profile on your hands. I’ve seen relatively high amounts of Bisabolol and Nerolidol in hemp terpenes before so it’s not totally outside the realm of possibility, just unusual. If it’s this, point me in the direction of whoever is pulling them because that’s very interesting for hemp. The terpenes would probably have a slightly higher viscosity than a typical monoterpene-dominant essential oil.
If it’s a simple decarb issue then you’d know within a few days. My guess is that it’s just air bubbles from drawing the oil up quickly with a syringe.

Warning: extremely limited sample size. Unknown method of action. Probably BS.
We have had some reports of the bubbling issue on a few batches even when dispensed at 45c (res) / 55c (needle) / 50c (valve / syringe)
We eventually resolved the issue by modifying the draw speed of the syringe so that little to no vacuum is pulled. The plunger is drawn back at approximately the same speed as the pressurized oil fills into the syringe, allowing the N2 to push it in rather than mechanically pulling the oil in via vac.
No idea why this worked, or if we just pushed past the oil that was showing this behavior… But something to start looking at. If we get any more customer reports, will update this thread with findings.

Good evening… I have this same issue but with delta 8. I’m using a 89% D8 and terps from floraplex… I’ve never seen this before… I did use a overhead homogenizer / mixer and got up to 4000rpm for about 10 to 20min thinking the bubbles would go away but its been 3 hours and the bubbles are still there… This D8 is high in viscosity… Please any help would truly be great because I did a batch of about 1000grams and now I’m worried if I screw this thing up…

Just fuckin heat it this time bro. You NEED to get your solution to at LEAST 80 celcius. The solution NEEDS to be LIQUID like WATER. USE THE MICROWAVE TO FULLY MELT YOUR MATERIAL BEFORE ADDING TERPS.

I’ve been going at it for 30 min trying to fix this bubble issue. Little bubbles keep forming on the oil intake hole. I pop the carts in air fryer and fix the bubble then a new one come out the little holes any help please
The coil is absorbing the oil, this creating the air bubbles.
Fill with a warmer temp product.
I had an issue with a certain cart that couldnt take 94% dusty and 5% terps. I dumped my product out of their carts and ran far away from their brand.

That is exactly what I’m using about 5% terps and I want to stay away from cutting agents it’s just my product is branded as adjustable airflow and theirs not many brands for adjustable airflow cartridges

Use the correct cart intake hole for your concentrate. Look like you need a 1.8mm or even a 2mm intake hole since yours is thick like mine is.
I’ve been thru 1000+ ac1005 carts. I cant say enough how FN I’m happy with these “old” carts. 0 failures, 0 returns.
