Amersham Biosciences AKTA FPLC System

The Amersham Biosciences AKTA FPLC System is a biocompatible, high performance liquid chromatography system for the fast and easy purification of proteins. Providing flexibility and reliability in every run, the AKTA system provides a unique combination of flow configuration and methods support for all chromatographic techniques including gel filtration (size exclusion) chromatography, anion exchange chromatography, cation exchange chromatography, hydrophobic interaction chromatography, and affinity chromatography. The compact and flexible design with an expandable rack allows the use of longer chromatographic columns and automation kits. The AKTA FPLC fully meets the demands of modern purification media by utilizing AKTAdesign and UNICORN to provide reliable results and system versatility. This system features flow rates up to 20 ml/min and pressures up to 5 MPa across one working platform for scale-up production.

The P-920 pump provides highly accurate and reproducible flow rates over the whole pressure range. Its chemical resistance makes it possible to use with corrosive liquids, such as organic solvents, as well as with high salt aqueous solutions. The P-920's high flow range makes it suitable for both analytical and preparative chromatography, and it is designed to work with a wide range of columns and gels from the UPC-900 monitor. The monitor provides precise on-line measurements of UV absorption, pH, and conductivity in liquid chromatography. The UPC-900 offers fixed wavelengths of 214 nm, 254 nm, or 280 nm with fast response. Also included is the M-925 mixer for a dynamic, single chamber unit which provides accuracy and reproducibility. The seven-port motorized valve, INV-907, can easily be used to load or wash the sample loop or wash the pump. The Frac-920 provides fraction collection up to 175 fractions in 12 mm tubes, or 95 fractions using 10-18mm tubes, or 40 fractions with 30 mm diameter tubes, depending on which rack is being used.

All of our equipment is fully tested to perform at factory specifications before being shipped.
