i dont think its filter material… as i used biomed syringe nylon filters…only other option would be coring? But the fiber was curved a little, it was SOOO small, and it would sink to bottom. So not air bubbles.
Only other option would be coring? So next go i will only use 23 gauge filer needle and 25 gauge air release.
I used a brand on amazon as air release, bh supplies 22 gauge. That may be the issue? But i would think ONE puncture with that size wouldnt cause coring every single time.
And again, each vial only had 1 floater, that was it.
I am at a loss….
