Nanosep Centrifugal Devices w/ Omega Membrane - 300K, Orange, 24/Pk - OD300C33

Pall's proprietary membrane technology and single-use device engineering converge to deliver the documented performance consistency that regulated processes demand. Nanosep spin concentrators reduce microliter sample volumes while salts and small solutes pass into the filtrate. Low-binding modified PES preserves dilute proteins in the retentate while resisting fouling through complex biological matrices and reaches target concentration factors in short cycles. Where a sample is scarce and dilute, molecular-weight-cutoff concentration delivers a recovered, high-yield retentate.

Key Characteristics

• Concentrates and desalts proteins and biomolecules by molecular-weight cutoff
• Broad aqueous compatibility across the pH 1 to 14 range
• Asymmetric membrane sustains high flow for fast spin times
• Low protein binding preserves dilute analytes for recovery above ninety percent
• Low extractables keep UV, fluorescence, and mass spectrometry backgrounds clean

Getting your biomolecule into the right buffer at the right concentration keeps your methods on track. Centrifugal desalting and buffer exchange brings your biomolecule into a working buffer across protein, peptide, and nucleic-acid preparation.

• 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.
• Buffer Exchange - Exchanges proteins and peptides into a working buffer while concentrating the retained sample volume in one spin.
• Enzyme Recovery - Concentrates dilute enzyme preparations at high recovery for activity assays and downstream characterization.
• 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.
