Switch automatically between 5 columns and one bypass using the column selection valve. The bypass option gives you the possibility to rinse your system with higher flowrates without damaging your columns. Furthermore it is possible to reverse the flow. This option has certain advantages. In affinity chromatography you can elute your sample in reversed flow and thereby increase the concentration while decreasing the sample volume. Another big advantage is the reversed flow column cleaning option. By this you elute contamination the shortest way and minimize damage to the column. Wetted parts of the valve are PEEK for the stator and Valcon E, a polyaryletherketone/PTFE composite for the rotor. The maximal flowrate for the valve is 50 ml/min. As an alternative and for higher flowrates you may use a column switching assistant (example AYELELEG).
You will receive valve together with the valve drive and fittings ready to use. The column selection valve can be mounted via the AZURA mounting bracket (article number A9853-2) to an AZURA L device. You can control the valve with KNAUER FPLC software PurityChrom® Bio.
