ISO Heptane Safe Filter cartridges

Does anyone have a good recommendation for a 4.5 x 10 inch filter cartridge supplier or manufacturer. I’m trying to filter some Heptane washed crude on it’s way into rotovap, and the feed assembly has stainless housings for 4.5 x 10 cartriges. I’ve done a fair amount of searching through suppliers of ptfe membrane cartridges but a lot of them have polypropelene endcaps and other parts that aren’t suitable for application with heptane. Thanks guys.

Ask evonic if they have it specialty is solvent membaranes and filters
