Japanese name: メンブレンフィルター（清澄化・除粒子）
Membrane filters separate particles by pore size. In biologics processing they handle secondary clarification, bioburden reduction and particle removal, usually after depth filtration and ahead of sterile filtration. Buyers compare membrane material, prefilter against finishing use, capacity before plugging, and small-scale devices for scale-down testing. The category includes makers from medical and water treatment fields, so confirm a track record in the bioprocess step itself. Below, each tracked product is paired with its maker and its Japanese distributor or subsidiary.
