Syringe filter -low or high protein binding?

[Naugahyde]

Or doesn't matter?
Just looking for some syringe filters for personal/small quantity last stage (to vial ) oil filtration. I'm thinking it's sterilisation/purification being the criteria here - & low protein binding being preferable? Choosing from a medical supplies ( Pall- life sciences ) catalogue & a bit lost to be honest!

I'm pretty sure it doesn't matter as long as they are 0.22 um
They are probably about filtering protein injectable meds like insulin, IGF1, HCG
they don't want to end up with an underdosed product because most gets stuck in the filter.

Biopharmaceutical solutions from R&D to manufacturing are precious commodities. Often they are heat labile and diltue, leaving cold filtration the primary method for sterilization. Some concerns have been raised about protein loss with filtration

If possible buy Posidyne filters as they seem more suitable to sterilization
Posidyne Positively-charged Nylon
6,6
For enhanced bioburden and pyrogen removal from
aqueous solutions


You Google bioburden and pyrogen yourself and you'll see.
