Filter membrane compatability chart

[nightprowler7]

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….

I'm not sure brother. But I've used probably 30 biomed scientific filters since this post. Not a single issue since then.

Keep in mind only 1-2% is BA. I think they chart the compatability with 100% BA

you can always add ba after filtering. If you are buying usp grade ba.
I add ba to sterile water and make my own bac water without any filtering and it has been fine.

Ah, that would make a big difference.

PVDF is ok for up to 20% BB

PTFE is best

No such thing as 'best' when it comes to sterility. Something is either sterile or it isnt. They both work. Pvdf been used around these parts since the 90s.

Who said anything about sterility? The question was about comparability with solvents.

Reading comprehension fail.
