Molecular cut-off centrifugal filters are specialized devices designed to separate molecules based on their size. They employ centrifugal force to drive solvent and small molecules through a semi-permeable membrane while retaining larger molecules above a certain molecular weight cutoff. This process allows for concentration and purification of samples by removing unwanted small molecules such as salts, solvents, or contaminants, while retaining larger molecules such as proteins or nucleic acids. Molecular cut-off filters find extensive use in various research and clinical applications, including protein purification, desalting, and sample preparation for analytical techniques like mass spectrometry or PCR. By selectively retaining or discarding molecules based on size, these filters enable efficient and precise molecular separation and concentration.
