Depth filter capsules are ready-to-use units for the filtration of media containing particles, or for removing biologicals in pharmaceutical and biotechnology applications. Eaton's BECO MiniCap (depth filter capsules for small volumes of media) are optimized for scale-up trials, e.g. for selection of suitable filter media and determination of the required filter area. Other applications are easy sample preparation, separation of cell debris, filtration of serum and cell culture media.
