The Amicon® ultra-4 centrifugal filter unit provides both ultra-fast spin times and ultra-high recoveries
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
