Amicon Ultra-15 Centrifugal Filter Unit

Provides both ultra-fast spin times and ultra-high recoveriesAmicon Ultra centrifugal filter units are the first devices to provide both ultra-fast spin times and ultra-high recoveries (typically 90%). The vertical membrane reduces concentration polarization for spin times as fast as 10–15 minutes. The heat-sealed membrane minimizes downstream extractables. The units are 100% integrity tested for reliable performance.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 10–15 minutes) Heat-sealed membrane minimizes downstream extractables 100% integrity tested for reliable performance Convenient sample monitoring with translucent housing and volume gradations Direct pipettor 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 HPLS Concentration of dilute or pre-purified proteins from column eluents Desalting, buffer exchange and protein dialysis Size exclusion and protein fractionation
