5 Station TFF Screening System
5 Stations of a Tangential Flow Filtration/Crossflow Filtration Process with completely independent control. It provides the ability to conduct parallel experiments in a compact footprint. There is complete batch control with 6 built-in programmable recipes.
- System interaction via a PC-based Graphical User Interface
- Real time trending and all data is written to a file for the permanent record
- Features use of PendoTECH Pressure SensorsTM that can be cleaned and re-used extensively
- Built in Proprietary PendoTECH Throttle Valve to control back pressure
- High pressure pumping with diaphragm pump that can provide up to 60psi/4 bar of pressure
- Compact load cells used for filtrate volume measurement and are used to estimate filtrate flow and flux
System includes:
- Completely and efficiently automates 5 Stations of a TFF/Crossflow Filtration Process
- Recipe based control of entire concentration and diafiltration process with multiple options for automated diafiltration end point
(filtrate volume and air in diafiltration line) - Pressure measurement and calculation of trans-membrane pressure (TMP) and delta-P with PendoTECH Pressure Sensors that
can be cleaned and re-used extensively or other sensors such as stainless steel transducers - Interact with the system via an easy to use graphical user interface (GUI) that includes a trending module with many advanced
features - Data collection to a file that is opened with Excel
- Alarms for pressures that shut-down the pumps
- Automation and alarm features allow the system to be operated with minimal user interaction
- Stainless Steel design with completely sealed front panel for use in clean environments where frequent wipe-down is required
and NaOH is used - Level sensors are used to precisely determine diafiltration and concentration setpoints
- Diafiltration volume maintained by gravity feed
- Non-invasive air detector end-point can be used for “fed-batch” process where product is fed to the main vessel and dynamically
concentrated via diafiltration mode - Diaphragm pump with range of 1-100mL/min & pressure to 60psi/4 bar with other pumps optional
- TMP control possible with proprietary PendoTECH Throttle Valve that is non-invasive to the process
- The system may be controlled remotely via a PC, iPad or smart phone by using 3rd party software; process details are visualized on
the graphical interface and the system interaction is via the PC so remote control is possible by simply accessing the PC
