| Patented technology* includes on-board software and hardware system that automates, optimizes and documents Dead-End Filtration. Introducing the FilterTec™ Lab Dead End Filtration System, the newest addition to the patented line of SciLog® Intelligent BioProcessing Systems. The FilterTec™ System is an exclusive software-driven fl uid delivery system that automatically adjusts feed rate and backpressure and documents 15 fi ltration parameters during your DEF. Ideal for DEF benchtop applications, including Filterability Studies, Vmax determination, and Filter-Train studies. Increases DEF fi lter utilization up to 35%. Instant overview of fi ltration progress to optimize fi ltration effi ciency. |

| Dead-End Filtration - Optimized |
|
| Optimized Dead-End Filtration (DEF) can be readily achieved with the FilterTec™ utilizing the SciLog® R/P Stat Method. This automated procedure maintains a user-defi ned pump rate (e.g. 100 ml/min) until a user-defi ned upper pressure limit (e.g 20 psi) has been attained as a result of fi lter plugging. At this point the system automatically switches from a constant rate to a constant pressure fl uid delivery (see Figure 1). The pump output is automatically regulated to maintain the desired pressure limit. With progressively increasing fi lter plugging, the pump output decays until a user-defi ned, low pump rate limit (e.g. 0.5 ml/min) has been attained, at which point the system will cease pumping. |
|
| In contrast to older DEF procedures, the new R/P Stat Method allows full utilization of the existing fi lter capacity and is accompanied by a signifi cant increase in total fi lter throughput. In addition to a fi ltration yield increase of up to 35% (compared to constant pressure throughput data), the R/P Stat Method provides a safe, walk-away automation capability. User-selectable alarm conditions are continuously monitored, including High/Low Pressure Alarms, Low Flow Alarm and Filtrate Weight/Volume Alarms. |

| WaterFilterability Studies - Made Easy |
|
| In addition to single-point pressure measurements, the FilterTec™ is capable of simultaneously monitoring up to three disposable pressure sensors. This capability is particularly useful in monitoring the pressure differentials of multiple fi lters in a serial or a parallel fi lter train. For a given process solution, excessive pressure build-up across a single fi lter element typically indicates the need for a larger porosity and/or larger area fi lter element. An optimally designed fi lter train will maximize the capacity, i.e. throughput, of the fi lter train. |
|
| The FilterTec™ contains application tools for developing and optimizing DEF fi ltration procedures. The FilterTec™ R/P Step-Scan mode allows you to modify the pump rate and/or pump pressure over a selected time interval. For a particular process solution, an optimized DEF fi ltration procedure may require a pump rate scan, e.g. continuous changing of the pump rate, for example, from 25ml/min to 250ml/min over a user-selected time interval or fi ltrate volume. Similarly, the FilterTec™ allows you to implement a fi lter pressure scan, i.e. a procedure by which the fi lter inlet pressure changes linearly over time (see Figure 2) until the selected fi ltrate volume has been attained. |

|
| Vmax Determination |
|
| Dead-End Filtration (DEF) by either Constant Rate or by Constant Pressure can be readily implemented with the FilterTec™. For Vmax determinations, the Constant Pressure method is utilized (see Figure 3). In the FilterTec™ “P-Stat” mode, the pump output is rapidly ramped up at a selectable rate until a user-defi nable pressure limit is reached. The FilterTec™ maintains the selected pressure limit by modulating the pump output. With progressively increasing fi lter plugging, the pump output decays until a user-defi ned, low pump rate limit (e.g. 0.5 ml/min) has been attained, at which point the system will cease pumping. |
|
| The FilterTec™ collects and documents the fi ltrate weight utilizing an electronic scale. The parameter T/W, i.e. “Time/Filtrate Weight” is plotted against “Time”. The inverse of the resulting slope represents Vmax. The FilterTec™ reports the instantaneous Vmax from the slope of neighboring data points. |
|
| Alternatively, Vmax data can be obtained by the R/P Stat method (see Figure 1). In this case, the pump rate decay data collected under constant pressure conditions is used to calculate Vmax. |

|
| Automated Data Collection and Trend Graphing |
|
| The FilterTec™ displays up to fi fteen (15) DEF-related parameters. You can scroll through three FilterTec™ display options, thereby obtaining an instantaneous overview of the fi ltration progress and status. When hooked up to a SciLog® printer, all information is printed out. Alternatively, a SciLog® application software, SciDoc, is used to summarize the fi ltration data and create graphical representations of the data on your personal computer (see Figure 4). |
|
| The SciLog®/SciDoc custom spreadsheet has three data fi elds: 1) Summary of all FilterTec™ related parameters including time/date stamp; 2) Information related to process solution and fi lter membrane. This information is fi lled in by the operator; and 3) PC display of up to 15 fi ltration related parameters that are updated at user-selected time intervals: |
