Chemical Restrictions
TangenX™ membrane cassettes are compatible with the following:
•
ACN (<15%)
•
DMF, DMSO (<40%)
•
DMAC (<15%)
•
Phosphoric Acid (<1M)
•
Sodium Hypochlorite (<400ppm)
•
Sodium Hydroxide (<0.5M)
TangenX™ membrane cassettes are NOT compatible with the following:
•
Pure aromatic and chlorinated hydrocarbons
•
Ketones
•
Polar aromatics
•
Aliphatic esters
CAUTION
In the event that the cassette is subjected to any of the conditions listed below, it is recommended
that you perform both cassette integrity and water flux tests to ensure your cassette is not
damaged. Damage may occur as a result of the following:
•
Dropping on hard surfaces, or other mechanical shock.
•
Poking with sharp objects on screened surfaces.
•
Excessive feed pressure.
•
Excessive permeate backpressure, or pressurizing the filtrate port.
•
Exposure to harsh chemicals.
•
Freezing.
•
Excessive heat.
•
Drying out - ultrafiltration membrane that is allowed to dry out can permanently
damage the pore structure.
TangenX™ SIUS™ PD cassettes must remain wet at all times to maintain product integrity and
performance.
