The PendoTECH PDKT-PCS-TFF is an advanced process control system designed for automating and monitoring Tangential Flow Filtration (TFF) and cross-flow filtration processes in bioprocessing labs and pilot plants. Model PDKT+PCS=TFF Serial Number 103657 Core Capabilities Process Automation: Manages concentration and diafiltration processes via pre-defined, recipe-based control. [1] Data Acquisition & Monitoring: Collects real-time data from various inline sensors, logging it to a central data file for Design of Experiments (DoE) and process development. [1, 2] User Interface: Operates via an intuitive Graphical User Interface (GUI) that allows operators to view process metrics, trends, and alarm parameters on one screen. As a standalone controller unit it features back-panel connections to integrate hardware such as: Pressure Sensors: Inputs for multiple single-use or reusable pressure sensors to calculate and monitor Trans-membrane Pressure (TMP) and Delta-P . Flow Meters: Interfaces for flow totalizing devices (e.g., mag meters, ultrasonic) to manage retentate flow. Probes: Dedicated inputs for conductivity, pH, and temperature. External Devices: Support for industry-standard pumps (peristaltic, rotary lobe) and scales/balances to automate endpoints (e.g., stopping the process based on filtrate weight). [1, 2, 3] Valves: Connections to automated diafiltration or throttle valves Dimensions (H x W x D): 6.125 × 16 × 11.5 inches (15.56 × 40.64 × 29.21 cm) Weight: 20 lbs (9.1 kg)
