Fraction Collection

Multiposition valves offer an easy solution for fractionation tasks. Whenever no advanced functionality of a fraction collector is needed, multiposition valves are an excellent and price-attractive alternative. The valve can be mounted on one side of any AZURA L module or integrated into the AZURA ASM 2.2L Assistant.

Column Selection

Switching between different HPLC columns does not always require manual intervention of the user. Multiposition valves can be used perfectly for this purpose. Install one multiposition valve before and one behind the columns that should be switched. With KNAUER valves, up to 15 columns can be connected, rerserving  one port of the valve for a bypass position. In combination with eluent selection valves, the HPLC system can in this way be upgraded to a automated method or column screening system.

Sample Selection

In preparative HPLC, samples can be introduced into a system using valves. If several different samples should be separated in a sequence without manual intervention, multiposition valves can be added to a system for sample selection. This rather small addition can lead to a significantly higher level of automatization of the whole preparative HPLC process.

I am a dummy copy. And I´ve been a dummy copy since my birth. It took me a long time to realize what it means to be a dummy copy: you make no sense. You stand out now and then by being completely out of context. Often, you aren´t even read at all. But does that make me a bad copy?

I know that I´ll never stand a chance of appearing in the Economist. But does that make me any less important? I´m a dummy! But I enjoy being a copy. And should you now decide to carry on reading me to the end, I´ll have managed to achieve something most „normal“ copies don´t achieve.
