Nanosep Centrifugal Devices w/ Omega Membrane - 3K, Gray, 500/Pk - OD003C35

Pall Corporation maintains the production controls and documentation standards established for regulated pharmaceutical and biotechnology applications. In a high-speed centrifuge, the Nanosep Omega membrane drives microvolume sample concentration and desalting. The modified PES surface protects dilute analytes through concentration and holds throughput across extended spins. Where a sample is scarce and dilute, molecular-weight-cutoff concentration delivers a recovered, high-yield retentate.

Key Characteristics

• Asymmetric membrane sustains high flow for fast spin times
• Broad aqueous compatibility across the pH 1 to 14 range
• Stable for centrifugal processing at temperatures up to 40 degrees Celsius
• Concentrates and desalts proteins and biomolecules by molecular-weight cutoff
• Low extractables keep UV, fluorescence, and mass spectrometry backgrounds clean

Concentrating dilute samples while clearing small-molecule interference protects the data your work depends on. Reliable centrifugal concentration delivers your sample ready for the next step before downstream assay, electrophoresis, or mass spectrometry.

Material

Polyethersulfone (PES)

Sterility

Nonsterile

Wettability

Hydrophilic

• Desalting - Removes salts and small solutes from biomolecule samples while exchanging them into a clean working buffer for analysis.
• Protein Concentration - Concentrates dilute proteins and antibodies above the molecular-weight cutoff for downstream assay and analysis.
• Enzyme Recovery - Concentrates dilute enzyme preparations at high recovery for activity assays and downstream characterization.
• Buffer Exchange - Exchanges proteins and peptides into a working buffer while concentrating the retained sample volume in one spin.
• Antibody Concentration - Concentrates monoclonal and polyclonal antibodies from dilute culture and purification fractions.
• LC-MS Sample Prep - Concentrates and clarifies protein samples ahead of liquid chromatography and mass spectrometry analysis.
