Amicon® Ultra-4 Centrifugal Filter Units ยี่ห้อ merck

Overview

• High recovery Ultracel regenerated cellulose membrane in a range of molecular weight cut-offs
• High retentate recovery of >90%
• Vertical membrane reduces concentration polarization for ultra-fast spin times (as fast as 5 minutes)
• Heat-sealed membrane minimizes downstream extractables
• 100% integrity tested for reliable performance
• Convenient sample monitoring with translucent housing and volume gradations
• Direct pipette sample access eliminates processing step to recover concentrate
• High concentration factors of 80–100X

Applications

• Concentration of biological samples containing antigens, antibodies, enzymes, nucleic acids, or microorganisms
• Purification of macromolecular components found in tissue culture extracts or cell lysates and protein removal prior to HPLC
• Concentration of dilute or pre-purified proteins from column eluents
• Desalting, buffer exchange and protein dialysis
