Depth Filtration System
The Depth Filtration System is a user-friendly, automated benchtop unit. Equipped with an integrated sensor-laden flow path and TC (Tri-Clamp) fittings compatible with most filter modules, it is widely used for the development of small-scale clarification and pre-filtration processes. It is particularly well-suited for handling high-value products or smaller volumes in clarification and pre-filtration steps. In the biopharmaceutical R&D field, the Depth Filtration System, with its high efficiency, serves as an ideal "lab partner" for daily small-scale clarification and pre-filtration operations.

System Features
Easy-to-Use Operational Interface
The Depth Filtration System is configured with a Siemens industrial PC that starts automatically upon system power-up. Via the touchscreen, users can easily manage and process system control information, conveniently monitor flow rates, temperature, and pressures, view system status, warnings, and alarm indicators, and input commands through the control panel.
Warnings and Alarms
The system can operate automatically at a set constant flow rate. Alarm points for the differential pressure (ΔP) between inlet and outlet can be configured with four types of settings (High/Low and High-High/Low-Low alarms). When a preset High/Low alarm point is reached, the system triggers a warning alert but does not stop operation, allowing for operational adjustments to return to a controlled working range. When a preset High-High/Low-Low alarm point is reached, the system automatically shuts down with an alarm to prevent potential permanent damage. The system is also equipped with an emergency stop button for immediate system halt if necessary.
A P&ID (Piping and Instrumentation Diagram) display monitors and shows all online parameters, including pump speed, feed flow rate, inlet pressure, outlet pressure, feed temperature, and differential pressure (ΔP), enabling easier real-time process monitoring. Parameter trend graphs allow quick review of key parameter changes during operation, providing valuable data support for process development.
Automatic Data Logging and Export
The system automatically logs all operational parameters (e.g., inlet pressure, outlet pressure, differential pressure (ΔP), pump speed, temperature), including time-stamped alarm and event histories for easy future traceability and analysis. Logged data can be saved as SQL database files on the computer and used to generate batch report files directly.
Linear Scalability and Production Condition Simulation
The system uses components standard in industrial production, such as diaphragm pumps and 316L stainless steel fluid pathways. This design simulates production conditions, allowing process simulation at lab scale to ensure smooth process scale-up. For small-scale production, an optional data logger compliant with CFR 21 Part 11 regulations is available.
