So I'm giving Primo a whirl and it seems the syringe doesn't care for it. It doesn't glide easily (almost not at all). (a 3cc syringe)
Is there a simple trick to fixing this?
I have this happen once in a while, you need to switch the syringe, can't fix the plunger, you just have to push hard basically. You can try heating up the oil like in warm water before pulling it into the syringe (NOT boiling water) just warm like real warm to the touch put the vial in warm up the oil shake well and then draw it in.
Also you might have a needle/pin that's too high guage like 25G etc try using 22G and it should let the plunger go smoother.
If you are using a 25g needle, switch to a 23g. You will notice a big difference.
bro primo you need thicker needle sometime, what brand you use
You need to change your needle...use a good quality needle next time...
What syringes are you using. I’ve never had this issue.
