Centramate, Centrasette, Maximate, and Maxisett Cassettes

Centramate Cassettes
Centramate cassettes are perfect for laboratory scale and development applications in TFF. Small area formats with 0.009 m2 and 0.018 m2 may be used with the LV Centramate holder for process volumes of a few liters down to a few milliliters. The 0.09 m2 format is used with the Centramate Stainless Steel or Centramate PE holders. Centramate cassettes are available in a range of channel formats and membranes to meet every application requirement. The cassettes are supplied with the same membrane and construction materials as used in the Centrasette Membrane cassettes.

Centrasette and Centrasette II Cassettes
Centrasette cassettes,available in the same range of membrane and screen formats as the Centramate cassettes, have been widely used for years in various process applications including concentration and diafiltration by the biopharmaceutical industry. Centrasette cassettes are available with membrane areas of 0.46, 1.9, and 2.3 m2 (5, 20, and 25 ft2). Larger cassette areas simplify installation in large TFF systems, reducing the number of gaskets required and minimizing risk of leakage

Maximate
The Maximate membrane cassette offers the opportunity to simulate the performance of the larger Maxisette membrane cassette on a smaller scale. The path length in Maximate membrane cassettes is identical to that used in the Maxisette format but the membrane surface area and hold up volume are proportionately lower, meaning that processing and optimization studies may be performed on smaller batches.

Maxisette
The Maxisette format has some distinct benefits that make it advantageous for large volume processes. Most important is that the volumetric flow rate required is 40 % lower compared to cassette formats like the Centrasette. This translates to a smaller pump and piping diameter required for the same membrane area with a corresponding reduction in energy cost. The larger porting in the Maxisette (almost 50% larger feed and retentate ports than the Centrasette II Cassette) provides lower resistance to high feed flow rates which results in lower pressure drops and easier cleaning.
