Pressure Cooker or Pressure Canner for flasking?

[Becca]

Hi Everyone! I know I have asked this questions before through private messages...but I just couldn't remember what the answer was since I have memory issues....would it really matter if I used a pressure cooker or a pressure canner to sterilize flasks? I would really like to get a pressure canner so I could use it for canning as well, a pressure cooker isn't supposed to be used for canning. So if someone has some advice for me I would really really appreciate it...oh....and any recommendations on what to get? I have a b-day coming up....and you know what I am going to ask for....lol. I want to make sure I get a nice quality one from the start!

Thanks!
