3. Operating Specifications
3.1 Recommended Cross Flow Rates for T-Series Cassettes with Omega Membrane
Table 3 lists recommended cross flow flux (CFF) rates for operating Pall TFF cassettes with
Omega membrane. Other parameters such as TMP and temperature can be evaluated at these
CFF values.
CFF = L/min/ft 2 or m 2 [retentate flow rate/membrane area]
The values listed under Processing Mode are recommended for use when processing a
sample. Higher flow rates are recommended for cleaning and sanitization (Cleaning Mode).
