Picture did not match with the text. It is misleading. It only has the filter but not the collection bottle.

Works well but the picture shows a media bottle. No media bottles came with the order only the top filter part. I little misleading.

Tested this new filter for the first time. Media trapped in the corners. Not sure why Corning switched to the square membrane design vs Millipore and Foxx Life Sciences Autofil round design? Liked the old Corning design better. Still love the other Corning lab products.
