Depth Filtration Bioprocess Fixture Type M, 22 m² (CAT#: STEM-L-0013-ZJF)

The depth filtration system is designed to remove large cell particles during the preparation of biological products, such as cell clarification (in bioreactor rooms) or intermediate product filtration (in purification rooms). The system primarily consists of a power unit, a cassette holder, a detection unit, and an automatic control unit.
The depth filter holder is used to secure primary or secondary deep filtration cassettes of a specific area. Driven by a power pump, the feed liquid passes through the cassettes, which intercept solid particles for clarification. The holder's horizontal design ensures the cassettes remain level during horizontal stacked installation, reducing residual areas and preventing airlocking.
