- Amicon® Ultra-4* and -15* Centrifugal Filter Units are designed for in vitro diagnostic use and intended for concentrating serum, urine, cerebrospinal fluid and other body fluids prior to analysis.
- The premier devices for concentrating 1 – 4mL or <15 mL
- 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
The Amicon® Ultra-4 and Amicon® Ultra-15 with Ultracel®-10 membrane with catalog numbers ending in “D” are CE marked
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
- Concentration of dilute or pre-purified proteins from column eluents
- Desalting and buffer exchange
