Looks like your only option for sterile PTFE botte tops is some korean labstore. All the other vendors (Autofil, Labforce and Celltreat) offer it only as non sterile.

If i have to guess, i would say the ulabs that use PTFE bottle tops just get the non sterile ones and yolo it. Not that i would recommend it, but i can't imagine them actually caring that much.

Anyways, order at your own risk lol

PTFE-H (Hydrophilic Polytetrafluoroethylene)

I do sterilty testing for bacteria and fungus at a biological labs near me.

Costs me 12 usd and i get the results after 4 days

But I live half of the year in a third world country. Not sure in europe they would agree.

I put the oil in a 1 ml sterile vial. I write on the sticker vitamin b12 and an expiration date.

I curious to know the process on that.. 4 days doesn't seem like it is enought to be able to incubate any growth...jano said 14 days and my sister said 15-20 so both of their processes must be simular.. either way are you able to provide me with the place that does it for 12$?
