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=01370Must 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.

Where to get glass baby jars? get them used? How do you know if Presto has 15 psi rating? I can't find that information in the spec sheet. Thanks Lloyd

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.

Email Presto first to make sure it's 15 psi. Also the 8 quart one is just big enough for 4 baby food jars on the rack, so the 6 quart might be smallish.
I use mine for cooking. I don't use any toxic stuff but even if you did, the concentrations would be super low in the cooker water and regular cleaning would be sufficient to clean it out.
Make sure the replacement parts are easily available, they should be for Presto. I have spares of all the seals, gaskets and regulators.

I checked that it is 15psi. Seems like a good cooker. I'll see if I can find a 8Q one Thanks again!

Here is what I have. It will give you an outline of what can fit in a capacity of 22 Quarts for this model.
This unit has three operating pressures 5, 10, and 15 PSI.
I hope this Pic link works. ecx.images-amazon.com/images/I/41hNjyYYQkL.jpg
Mirro 22 quart pressure cooker/canner heavy duty aluminum M-0522-11
Capacity - 22 Quarts (Liquid), 30 Half Pint Jars, 16 Pint Jars, 5 Quart Jars
You may find yourself disappointed with the small capacity later on.
You may also want to consider how much medium is in one batch and how many times you have to use the pressure cooker to finish that batch.
Just some thoughts to share.

Is stainless steel far better than Aluminum? Should I start with Aluminum cooker?

Come to think of it, I don’t recall seeing a large cooker not made of aluminum. I have seen one made of aluminum sandwiched between stainless.
I believe the reason they use aluminum is because it is a very good heat conductor and will heat the cooker evenly. It can’t be because it’s cheap metal, because it’s not.
The reason I don't mind using it, is because I didn't buy it for cooking my food. I would never use aluminum for food.

Those are great points, thanks Mixta. That's what I thought too, perhaps I will just buy a 23Q cooker purely for TC.

I bought stainless steel as I am afraid of pressure cookers blowing up.
