Optimized membrane remains perfectly flat after filtration to stay in constant contact with culture media

Unique funnel shape and hydrophobic material minimize residue and maximize sample volume

Innovative funnel assembly eases sample collection and prevents leaks

 Stay-in-place lid prevents contamination during filtration

Specialized rim design keeps forceps away from filtration area during transfer forceps from accidentally touching the membrane filtration area during transfer

Easy manifold access enables better cleaning

Transparent funnel design allows user to see when filtration is complete from any angle

Unique membrane base shape enables easy membrane transfer

Stackable units save space in the work area
