Best syringe to inject vape cartridges with??

What is the best syringe for transferring distillates to vape cartridges?? I understand flat needle is ideal, what about glass syringe or plastic? What is the best syringe and needle to handle super thick disilattes?

Any suggestions

It seems like the small ones with the curved tips are favored.

Like this. But probably a bit smaller. You can try finding glass but they are rare and expensive.

I understand there are a couple different options, glass syringe or plastic Repeater Pipettor syringe, I understand with the repeater syringe I have to heat up my oil 160°-190° and keep Distillate at a water type consistency throughout injectioning or syringe could jam up, with plastic Repeater Pipettor I don't have to get Distillate as hot and there is the problem of terpenes causing reaction with plastic, so I've heard, so what is the best way to fill 500+ cartridges, with plastic Repeater Pipettor syringe or glass syringe??? Any comments or suggestions would be greatly appreciated
