Polypropylene can melt as low as 130°C and pressure cookers can go as high as 121°C so these should be Ok. Glass baby jars are pretty well free and the lids are relatively cheap. The latter are much sturdier. I don't suggest that pressure cooker. Too many functions, will likely break down. This is mine, www.gopresto.com/products/products.php?stock=01370
Must be 15 psi to kill all spores. Don't buy unless it's 15 psi. It's easy and cheap to buy replacement parts for the Presto one. Always use distilled (pure) water in the cooker to protect the pressure system.
Baby food jars: find someone with a baby and offer to take the dirty jars away for free; look for expired jars in cheap stores and make them a cheap offer; wait for a baby food sale, sometimes $0.50 a bottle, use the food for your invertebrate culture.
Presto pressure cooker: I emailed the company before buying plus I have proof of sterilization.
