Description

BFTT-RC-3: Single-Use RC TFF Cassette

The BFTT-RC-3 is a single-use membrane cassette with a regenerated cellulose (RC) membrane for tangential flow filtration (TFF). This cassette for single use is available with different cut-offs, membrane areas and screen configurations.

Tangential flow filtration, also known as crossflow filtration, is used for concentration and diafiltration. During this process, the liquid flows along the membrane surface. Part of the liquid passes through the membrane as permeate, while retained components remain in the retentate.

Twelve Cut-Off Options from 1 to 300 kDa

The BFTT-RC-3 product range includes the following molecular weight cut-off (MWCO) values: 1, 2, 3, 5, 10, 30, 100 and 300 kDa.

In addition to the S versions, specific H and L versions are available:

1 kDa: 001S and 001H
3 kDa: 003S, 003H and 003L
100 kDa: 100S and 100H

The appropriate cut-off and membrane version depend on your application, the components you want to retain and the required separation.

Five Effective Membrane Areas

The BFTT-RC-3 is available in the following effective membrane areas:

0.01 m² — 100 cm²
0.02 m² — 200 cm²
0.11 m²
0.50 m²
2.50 m²

The required membrane area depends on factors such as process volume, liquid properties and target processing time.

Two Screen Configurations

The BFTT-RC-3 product range includes two screen options:

A – Tight screen
C – Standard coarse screen

The cassette is offered with an S – Standard body. Available combinations of cut-off, screen and membrane area vary by configuration. Not all options can be combined.

Concentration and Diafiltration

During concentration, liquid passes through the membrane, increasing the concentration of retained components. Diafiltration is used for buffer exchange or the removal of small components that can pass through the membrane.

To select a suitable TFF cassette, the RC membrane, cut-off, effective membrane area and screen configuration should match your liquid and process conditions.
