Septa cap for media bottle

[Sampei]

So I have found these silicone stopper for media bottle cap with holes.

Are these ok for being sterilized with dry heat? does the stopper need to be PTFE coated or can be only silicone too?

Those are butyl stopper, not good for dry heat sterilization, I found septa silicone PTFE coated perfect for dry heat sterilization.

are those i pictured gonna work if i sterilize them properly, obviously no heat , but can i just soak them in 99% isopropyl alcohol? or what method would i use to properly sanitize them? Tia brother

Soak them in isopropyl yeah or if you wanna go the extra mile, pressure cooker inside autoclave bags and sanitize them that way, that's 100% sterile 30 minutes at 15psi will have them shine and ready to go

I bought an oven only to be used to sanitize everything so I need stuff that can sustain at least 160degrees of heat
