Mode
Explanation
ATF DUAL
Independent
The phase of each XCell ATF® Device runs wihout
dependency on the other.
In-Phase
The pressure and exhaust strokes of both XCell ATF®
Devices occur at the same time.
Out-of-Phase
The pressure and exhaust strokes of both XCellATF®
Devices occure in an altenating fashion. This is useful to
keep a bioreactor volume constant when running two
XCell ATF® Devices on one bioreactor and is used most
Note: When two ATFs run independently, the set points can be adjusted in their respective ATF Flow-
A or ATF Flow-B pop-ups. When the two ATFs are run In-Phase or Out-of-Phase, ATF Flow
setpoints for both the ATF A and ATF B pop-ups are linked and must be the same. Edit the
setpoint for both devices at the same time in either the ATF-A Flow and ATF-B Flow Pop-ups.
