Breaking Down the Features of Pall Cassette 10k Omega Centramate OS010T02

Specifications

The Pall Cassette 10k Omega Centramate OS010T02 is built around a core filtration technology designed for biomolecule processing. Its defining characteristic is the 10K MWCO Omega Membrane, signifying a 10,000 Dalton Molecular Weight Cut-Off. This specification is crucial as it determines the size of molecules that will be retained by the membrane during filtration.

This precise molecular weight cut-off makes it ideal for concentrating and purifying proteins, monoclonal antibodies, peptides, nucleic acids, carbohydrates, enzymes, and oligonucleotides. The cassette design itself is engineered for tangential flow filtration (TFF) within the Pall Centramate system, which maximizes flow efficiency and minimizes membrane fouling. This integrated cassette approach simplifies setup and operation compared to traditional stirred cells or more complex filtration skids.

The catalog number for this specific unit is 97049-474, and its supplier number is OS010T02. While specific dimensions are not detailed in the provided product information, the cassette is designed to fit within the Centramate platform, implying a standardized form factor for easy integration. The material composition of the cassette housing is typically robust polypropylene, ensuring chemical compatibility with a wide range of biological buffers and processing fluids.

Performance & Functionality

In its primary role, the Pall Cassette 10k Omega Centramate OS010T02 performs exceptionally well, delivering on its promise of efficient biomolecule concentration and purification. The 10K MWCO Omega Membrane provides a sharp separation, effectively retaining target molecules while allowing smaller impurities and buffer components to pass through. I’ve found the filtration rates to be consistent and predictable, which is essential for reproducible experiments.
