Consieve® UFC tangential flow filtration (TFF) cassette is made of RC (Regenerated Cellulose) membrane, which provides extra low protein bindings and wide chemical compatibility. It can be compatible with organic solutions as well. Which make it suitable for ultrafiltration of various biological products such as antibodies, recombinant proteins, and blood product, etc. The cassette is easy to clean, install and has a high retention efficiency, with low working volume and high efficiency which ensures product yields.

Consieve® UFC TFF cassettes are available in a wide range of molecular weight cut-offs from 3 kDa to 300 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 downstream 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)
