The PendoTech TFF Process Control and Data Acquisition System PDKT-PCS helps you automate your workflow with in-line process monitoring and data collection.  This process control system features 6 built-in programable recipes for complete batch control and diafiltration with added options for filtrate weight, conductivity, pH, total flow, and air in the buffer feed line. The PendoTech TFF also features no limit on process scaling, real time trending and data that’s saved to a file for recording later, as well as built-in conductivity, pH & temperature measurements. This tangential flow filtration system integrates though connections in the back for different types of pumps and brands of scales, conductivity and pH probes, filtrate flow meter, a temperature sensor, PC control, and two addition inputs that can be configured for alarms points, UV or an additional flow meter. This process controller can also be configured with 3rd party software for mobile control from a PC, iPad or smartphone so users can track progress while away from the instrument.

The PendoTech TFF Process Control and Data Acquisition System comes equipped with a throttle valve that receives a pressure signal and controls back pressure. This throttle valve helps vary the flow path without the valve contacting the liquid. The pendotech throttle value has a quick selection of tube size, toggling between run and load, and a one touch real-time adjustment to compensate for different pumps and configurations.
