Consieve® UET tangential flow filtration(TFF) cassette is made of asymmetric mPES (modified Polyethersulfone) membrane, which provide high flow rate, low protein bindings and wide pH compatibility. The cassette is easy to clean, install and have a high retention efficiency, with low working volume and high efficiency which ensures product yields.
Consieve® UET TFF cassettes are available in a wide range of molecular weight cut-offs from 5 kDa to 750 kDA. It can be easily scale-up from Lab, Pilot to Process scale with a wide volume range from 0.5L to 20,000L. They are widely used in separation, concentration and diafiltration in downsteam bioprocessing.
The cassettes should be used with Cobetter TFF Stainless Steel Holder:
EFA 0.01m² cassettes use with TFF Holders (0.01m²)
EFA 0.11m² cassettes use with TFF Holders (0.11m²)
EFA 0.46m²or 2.33m²cassettes use with TFF Holders (0.5m²)
