The depth filtration system is designed to remove large cell particles in the preparation of biological products, such as cell clar- ification (in bioreactor rooms) or intermediate product filtration (in purification rooms). The system mainly consists of a power unit, a cassette holder, a detection unit, and an automatic control unit.
The depth filter holder is used to hold primary or secondary deep filtration cassettes of a given area. Under the action of a power pump, the feed liquid passes through the cassettes, which intercepts the solid particles in the liquid for clarification. The horizontal design of the holder allows the cassettes to stay leveled in the case of horizontal stacked installation, so as to re- duce residual area and avoid airlocking.
