sterilizing

I've seen people say that unironically. But that doesn't even make sense, right? Obviously they are sterile when they come out the factory right? But let's say they were contaminated with bacteria or whatever. How tf would you know? Call me an absolute retard idc

My sterilization process for used media bottles or new ones. I do not reuse vials. However I could, I just find the cleaning process of trying to get old oil out very tedious. 1. Clean all glassware in sink with hot water and lots of quality dish sop. WHY? U want all the old oils completely...

So, Im gonna be sterilizing equipment like vials and beakers and graduated cylinders. My question is how do I transfer it from the oven to my workstation without de-sterilizing the equipment. How do I keep the vials and stoppers on standby for when I'm ready to fill them up? I was thinking...

Read allot about people using pressure cookers for an autoclave. I was curious if anyone had any experience with this, and if they knew approx what size pressure cooker you would need to autoclave 50 vials at a time? much appreciated!
