- wash things with alcohol/distilled water
- Instapot sterilization cycle (30 min) for things that fit into it. (one of the few consumer presurecookers that is rated at 120psi necessary for adequate sterilization).
- oven at 200F for 20-30 min, mostly to make sure everything is dry.
i put Everything, that needs to be sterile and fits, through this cycle, vials, stoppers, circle filters for filter apparatus, filter apparatus itself.
i don't use the bottletop dispenser, but if it's listed as autoclave safe, no reason any parts of it would be able to run through the above process.
