ÄKTA Pure Protein separation and purification platform

The ÄKTA ​pure systems are used and designed for purifications of mainly proteins. All kind of chromatographically techniques, like ion-exchange chromatography (IEX), size-exclusion chromatography (SEC) and more techniques can be used.

The system is present in 2 variants, the pure 25, with a maximum flow of 25 ml/min and the pure 150, with a maximum flow of 150 ml/min. The pure 25 is the analytical system, while the pure 150 is the semi preparative system.

The sample can be applied via a sample loop, an external autosampler or directly via a sample pump. The fraction collector can collect the fractions of the purified compounds in small or large volumes.

The unicorn software makes it easy to scale-up from the analytical system to the preparative purification system. It is also easy to create methods and monitor runs, pH, conductivity and UV scouting, and evaluate the results.
