I've always used Whatman filters, but I noticed the Millipore filters that have 20% more filter area (should make filtering easier).

Has anyone used the Milipore filters? What's your opinion of them? They cost the same as the Whatmans.

Here's the one that I am looking at:

Thanks guys. Better off to ask than to try them and make a mess if they split.
Whatmans always work.

I got some once and I don't remember what brand they were (come in a kit), but I blew them both out. I remember they didn't look like whatmans though.
I always buy extra whatmans to keep around.

I have always used Whatman when experimenting on Thee Animal. If it ain't broke why change it (the prices are similar). Thee Animal has never got an infection or any problems.

By the way, has anyone researched filtration of pyrogen from IGF powder. I'm cool from your posts on killing the bacteria (AA or BA) but want to make sure I am not missing something improtant on removing pyrogen. Do I need to do this and if so, how? Everything I've seen relates to water purification on large scale, bot at all relevant to my research. Thanks again

Quick update:
I ordered two of the Milipore filters just to compare to the old favorite Whatmans. After trying the first one, I threw the second one out and finished the batch using Whatman's. Whatman's are significantly easier to filter thru compared to the Milipore's. Maybe the larger surface area of the Milipore was the reason that it took more pressure to flow thru, but whatever the reason was - the whatman's were much easier to use. Dang I hate sore fingers, lol.

A member on another board posted this info:

"here you can get the exact same cellulose acetate filters as whatman, 50 for $74.00, so 1.48 each.

http://www.coleparmer.com/catalog/product_view.asp?sku=0291512&cls=1261&par=&cat=1&sch=80&pfx=&lstBool=true"

I haven't tried these filters. Does anyone here know anything about them? Sure is a great price.
