Part A: FilterTec Plus Hardware
1.0 Overview:
The FilterTec Plus is a DEF laboratory-scale filtration system that automates filterability studies
and dead end filtration processes. In DEF, process solution is pumped through a filtration
device, typically a 47mm diameter disk filter or something larger, having a user-selected
porosity. In contrast to older, less efficient DEF procedures, Parker’s new “Pmaintain” Alarm
method automates direct flow filtration (DFF) of dilute protein solutions while providing a 35-
50%* increase in filter utilization and filtration yield. (*process solution dependant)
Parker’s new “Pmaintain” Alarm method consists of the following steps: Initially, a user-defined
constant pump rate is implemented in Constant Rate Mode until a user-defined pressure limit is
reached. At this point, the fluid handling system automatically switches to a constant pressure
delivery, i.e. modulating the pump output until a user-defined lower filtration flow limit (collection
rate) is reached and the pump automatically stops.
The FilterTec Plus system provides ease of use and operational safety:
Several user
definable alarm conditions can be continuously monitored and displayed.
The user defined alarms include:
High Pressure Alarm
to monitor filter
plug-up conditions, the Pmaintain Alarm is
part of this Alarm menu, will change the
unit from Constant Rate to Constant
Pressure at a user-defined limit.
Low Pressure Alarm
to monitor system
leakage.
Low Flow Alarm
to monitor filter plug-up
conditions. Used along with Pmaintain in
High Pressure Alarm to terminate the
filtration process.
Hi Temperature
to monitor the
temperature of your solution.
Cumulative Volume Alarm
to monitor
total volume based on the feed rate.
Filtrate Weight Alarm
to quantitatively
measure the filtrate yield.
Run Time Alarm
that stops the pump
action when a user defined filtration time
has elapsed.
Hi and Low Analog Alarms
allow you to
monitor inputs from other devices to
control your process. (pH, conductivity or
turbidity sensors, etc.)
All alarms provide an auditory signal; the pump stops when user defined alarm limits are
exceeded. Alternatively, any alarm can be selectively disabled. All pump filtration, as well as
alarm parameters can be printed out at user defined time intervals with a Parker serial printer.
Alternatively, all of the collected data can be sent to a supervisory computer for data archiving
using SciDoc or HyperTerminal.
The Masterflex Easy-Load II peristaltic pump heads can accommodate PharMed and Platinum-
cured Silicone pump tubing, including sizes 13, 14, 16, 25, & 17. If equipped with the lager
model, sizes 15, 24 & 35 can be accommodated. Feed rates for all pump tube sizes are factory
calibrated; however, the user can easily recalibrate with a single keystroke from the FilterTec
Plus front panel. The pump head delivers flow rates ranging from 0.03 ml / min. to 2200 ml /
min. for each of the two pump channels depending on motor rpm.
NOTE:
The FilterTec Plus usually is configured with a 160-rpm motor. However, if your flow rate
needs require, the FilterTec Plus is available with either a 600-rpm or 8-rpm motor. In Setup:
Pump: Motor: Rpm, select the RPM of your installed motor. By doing so, the FilterTec Plus will
select the appropriate factory installed calibration curves and flow rates.
