BFTT-RC-1: Reusable RC TFF Cassette

The BFTT-RC-1 is a reusable membrane cassette with a regenerated cellulose (RC) membrane for tangential flow filtration (TFF). This technique, also known as crossflow filtration, is used to concentrate liquids and perform diafiltration, for example for buffer exchange.

During TFF, the liquid flows along the membrane surface. Part of the liquid passes through the membrane as permeate, while retained components remain in the retentate. The selected cut-off helps determine which components are retained and which can pass through the membrane.

Cut-Offs from 1 to 300 kDa

The BFTT-RC-1 product range includes the following molecular weight cut-off (MWCO) values: 1, 2, 3, 5, 8, 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 membrane version and cut-off should be selected based on your application, the components you want to retain and the required separation.

Seven Effective Membrane Areas

The BFTT-RC-1 is available in the following effective membrane areas:

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

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

Screen and Body Configurations

The BFTT-RC-1 product range includes three screen options:

A – Tight screen
C – Standard coarse screen
V – Suspended screen

The body is available as S – Standard body or B – Flow B. Available combinations of cut-off, screen, membrane area and body 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.
