Electric valves for many injection and/or switching tasks

Depending on your task, you can chose between 2-position or multi-position valves:

  • 2-position valves are used mostly for injections, but can be used for complex switching systems as well. All ports are located in peripheric positions. The channels always connect two of these ports.
  • Multiposition valves are used for fraction collection, eluent selection or column switching. They have an extra port in a central position and one channel which connects the central port to one of the peripheric ports.

If more than one valve is needed for your application, it might be helpful two combine these as units in one stackable AZURA ASM 2.1L device.
