FilterTec™ Normal Flow Filtration* (NFF) System
 
FilterTec Advantage:
Patented filtration method provides significant cost savings. This automated method results in a 30-50% increase in filter
   capacity utilization.
Dedicated application tools for filterability testing and Vmax determination with automated data collection of up 15 filtration
    parameters.
No need for manual data collection.
The FilterTec is easy to use and has a small (6” x11”) footprint.
 
Automated Normal Flow Filtration (NFF) ;
Laboratory Filtration, up to 4.0 liters/min
FilterTec NFF System provides significant cost savings when used with any commercially available membrane or depth filters.
The FilterTec utilizes a peristaltic pump head as well as a disposable pressure sensor (see SciLog’s disposable sensors).
A user-selected pump rate (or time-based rate ramp) is implemented until a user-defined pressure level is reached, e.g.
    20 psi.
At this point, the filter is substantially plugged-up, the FilterTec switches from a rate control to a pressure controlled fluid
    delivery.
The FilterTec automatically maintained the selected pressure limit by modulating, i.e. decreasing, the pump output.
When the pump output reaches a user-selected lower pump rate limit, e.g. 1 ml/min, the FilterTec safely stops the filtration
    process.
 
Automated Filter Capacity Determination, Vmax:
Generates/documents Filtration Scale-up Data
For Vmax determinations the FilterTec utilizes a pressure sensor and an electronic scale.
    The FilterTec rapidly ramps up the pump rate and maintains a user-selected pressure.
The FilterTec collects and documents the filtrate weight. The parameter “Time/Filtrate Weight” is plotted against “Time”.
    The inverse of the resulting slope represents Vmax.
Up to 15 filtration parameters are monitored and documented during filtrate collection.
