Centrifuge Filter Tube, 15mL, 50000 MWCO(Da), Nonsterile, 12/Pk - CFT50000

Tisch Scientific welcomes bulk and blanket orders with volume discounts. In a centrifuge, the hydrophilic RevoSeizer polyethersulfone membrane drives 15 mL sample concentration and desalting. Hydrophilic PES sustains high flow for fast spin times while concentrating species held above the molecular-weight cutoff and stays stable across the pH 1 to 14 range. For protein and biomolecule work, the hydrophilic RevoSeizer membrane resolves the spin into a concentrated, ready sample.

Key Characteristics

• Broad aqueous compatibility across the pH 1 to 14 range
• Low protein binding preserves dilute analytes for high recovery
• Hydrophilic membrane sustains high flow for fast spin times
• Direct aqueous sample loading without pre-wetting or conditioning
• Concentrates and desalts proteins and biomolecules by molecular-weight cutoff

Recovering concentrated, salt-free protein from a dilute sample sets up every downstream assay you run. Reliable centrifugal concentration delivers your sample ready for the next step before downstream assay, electrophoresis, or mass spectrometry.

• Sample Concentration - Reduces dilute sample volume while retaining target biomolecules above the rated molecular-weight cutoff.
• Buffer Exchange - Brings concentrated proteins and peptides into the working buffer required by the downstream analytical method.
• Protein Concentration - Concentrates dilute proteins from buffers and fractions above the molecular-weight cutoff for analysis.
• LC-MS Sample Prep - Concentrates and cleans protein samples before liquid chromatography and mass spectrometry analysis.
• Nucleic Acid Concentration - Concentrates dilute oligonucleotide and nucleic-acid samples ahead of downstream molecular workflows.
• Desalting - Removes salts and small solutes from biomolecule preparations while exchanging into a clean working buffer for analysis.
