I purchased these for my ameda pump and it’s keeps popping open when I use them it is rather frustrating.What can I do to provent this from happening?

HI, this item is NOT designed for ameda pump. you have bought the wrong item. for Ameda, maymom has its line of products to fit ameda pumps. please use keyword: maymom ameda on amazon to search for them.

Are these microwave safe like the original Spectra parts? I'd like to be able to put these in a microwave steam bag for easy cleaning.

YES, they are microwave safe. Please note, microwave is mainly for sterilizing. You will still need to hand clean any visual milk residue off first with soapy water, and rinse with clean water. After that, put them in the microwave bag.
