PendoTECH TFF Process Control System™ is an optimal solution that adds automation and data collection to a Cross Flow / Tangential Flow Filtration – TFF) Process. The system includes a powerful yet easy to use Graphical User Interface and recipe based control of entire concentration and diafiltration process with multiple options for automated diafiltration end point (filtrate weight, conductivity, pH, air in feed line with non-invasive detector, total flow). Pressure measurement and calculation of trans-membrane pressure (TMP) and delta-P with PendoTECH Pressure Sensors™ which can be cleaned and re-used extensively or other pressure sensors/transducers. Industry standard scales & pumps (peristaltic, rotary lobe, diaphragm, etc.) can be interfaced with the system along with other optional accessories to create an advanced yet flexible system that can be configured as needed. It is ideal for process development and a pilot plant where the project requirements change.
