Used TangenX™ SIUS™ PD Cassette Disposal
TangenX™ SIUS™ PD cassettes are removed from the clamp by reversing the cassette installation
procedure. If the cassettes are difficult to separate and remove from the stack, a thin plastic
spatula

can be slid under the edge of the cassette to break the seal. Cassettes can then be disposed
of in a similar fashion to other disposable process equipment.
One cassette extractor is included with each shipment of TangenX™ SIUS™ PD cassettes.

Unused TangenX™ SIUS™ PD Cassette Storage
Membrane cassettes must remain sealed in their original packaging prior to use to maintain their
characteristics, integrity, and prevent microbial growth. Below are critical factors to remember
when storing unused TangenX™ SIUS™ PD cassettes:
•
Recommended storage temperature:
-
4°C to 25°C
longer than 7 days (long term)
-
50°C
less than 7 days (short term)
-
Do not freeze cassettes

Membrane Operating Characteristics
Take care to use the membrane at the lowest pressure possible while still producing consistent
permeate flow. Although higher operating pressures initially improve flow rate, they also promote
increased concentration polarization and membrane compaction, which ultimately limits flow. With
very low NMWL membranes, lower operating pressure may also reduce the retention of salts and
very low molecular weight species.
Maximum operating temperature: 50°C
