MCE Gridded Membrane Filter Sterile, 47mm Diameter and 0.45um Pore Size, Individual Pack Membrane Disc Filter, Hydrophilic Filter Paper, Pack of 100

They are as described and same as pictured.

Wanted to filter undissolved/suspended fluorescein dye from water. Completely failed filtering because it just didn't allow and water flow through it.

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.

Good filters get the job done, packaged nicely and well priced compared to competitors

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!

Functional. Though Much smaller than expected, not adhesive they did work. And customer service was great

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.

Used for water testing & worked well
