This is a great product, so far works as the top brand membranes. Be aware that this is inexpensive membrane filtration, meaning that most of the protective stuff other brands have is missing here. You need to be more careful in the handling and storage, but the price difference makes it worth the effort.

We purchased these to perform thermotolerant fecal membrane filtration testing. They perform comparably to the ones we used previously from Fisher Scientific that were twice the price of these. These are a great value!

I can make them work in a 56 mm funnel but to big for universal 47mm, another star off for little information provided on compatibility only really recommend these for biological application.
