Yeah but what's the prices? LolLooks 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)
and
PTFE-D (Hydrophobic Polytetrafluoroethylene)
