Japanese name: 分取SECクロマト担体（メディア）
Preparative SEC resins separate molecules by size in gel filtration. They are used in the final polishing step to exchange buffer and remove aggregates. Applications run from desalting to high-resolution fractionation, and the main question is where to cut between the target protein and its impurities, so buyers select by fractionation range. This page lists size exclusion media by maker.
