A few sources do. I believe muscle candy and Axle labs both had pressure cookers in their intro post instead of autoclaves
My dentist has both so I'm certain they are equally effective. Given you're following the direction for sterilization and not canning lol

Yep, I've used a pressure cooker for sterilising glassware myself in the past. It's actually quite similar to using an autoclave.
Both pressure cookers and autoclaves use steam under pressure to sterilise, effectively eliminating any unwanted microbes. The main difference is that autoclaves are more precise and are built for heavy-duty, consistent use. However, for steroid homebrewing, where the sterilisation needs might not be as demanding as in professional settings, a pressure cooker can be quite effective.
While a pressure cooker might not provide the same level of control or capacity as an autoclave, it's a more accessible and cost-effective option for those just starting out in homebrewing. Just be sure to keep a close eye on the sterilisation process to ensure your glassware is thoroughly sterilised.
Best of luck with your brewing!

You just gotta cook it longer in a pressure cooker since the PSI usually doesn't get as high. You'll have to reference the user manual and use the correct settings (probably canning), and just run it a bit longer.
Honestly not gonna be completely sterile without a vacuum hood and lab gear. Id wonder for a homebrewery if just a 70%IPA rinse would be more than enough...
Just do what you can. Junkies inject far less than sterile into their veins just fine.

Pretty interesting study on use of pressure cookers for sterilization.

Biggest issue is that most autoclaves have a drying cycle and the pressure cookers do not.

Why not just put ur glass in a ziplock bag right after pressure cooking?Pretty interesting study on use of pressure cookers for sterilization.

Zip lock bags aren't sterile
There are special bags for medical instruments or glassware that are made for this

I've always just used my oven
Worked fine for many years no infections
Wash, rinse in isopropyl alcohol, rinse in distilled water, put on piece of aluminum foil and then make a aluminum foil tent over it. Bake, and let cool

What time and temp do you bake it?
400f for 1 hour should be good enough. Butyl rubber stoppers don't do well at this heat though.

425F, 1 hour

Yes sorry. I should have clarified, I only bake my beakers. I buy vials pre sterilized, Definitely don't put vial stoppers in the oven too
While certainly not a bad idea. In my 20+years home brewing i have never used anything like a pressure cooker, oven or autoclave. Wash with alcohol then filter has worked well for me. But i just brew small batches at a time and can control my surrounds easily.

this is my method as well @Spaceman Spiff been doing this method for 20 years now. never an issue. wash bottles and butyl rubber stoppers in 70% iso, place upside down on a clean dry rack, tarp it under a sheet of plastic wrap. clean surroundings are important cleanliness measures should be taken. dont want airflow stirring dust or flakes n shit. i have a more involved setup than this but this covers the basics. ive used glove bags in the past as well.

yeah pressure cooker seems kind of pointless if you aren't running a vacuum hood or the like.
But 70% iso > 91% when it comes to sterilization.

ya youre right i just looked i use 70% as well got it in a big 5 gal pale but use it for other shit around here
Seems there are multiple ways to get the same results. You should continue with what works for you. I don't worry about dust or flakes as my filtering takes any thing like that out. and i use presterilized vials so i don't have to worry about those. I just need to sterilize my glassware.
Same thing, I don’t need to be fancy. Wash your beaker with water and soap, alcohol, distilled water then heat it in the oven to dry out.
Brew a few batches of 100ml compounds then filter into premade sterile vials. You can do 500ml in 2-3 hrs, its simple and straightforward as it comes. Downside is forearm pumps from the filtering process unless you’ve got a set up like spaceman spiff utilizing the caulking gun.
I just consider it a forearm workout and don't sweat the pump!
