TFF cassettes are stacked flat-sheet membranes for tangential flow filtration. They concentrate proteins or viral vectors and exchange buffer (UF/DF) in formulation and drug substance preparation after capture purification, and they scale from lab to production. Buyers compare membrane material (cellulose-based for recovery and cleaning, PES types for flux), molecular weight cutoff, single-use against reusable cassettes with holders, and screen channel and membrane area. This page lists the products we track, their makers, and their Japanese sales channels.
“Where to buy in Japan” shows only sales relationships we have confirmed on the company’s or the distributor’s own website. “Not yet confirmed” means we have not checked yet, not that the product is unavailable in Japan. Product names link to the maker’s own page.
