Valve with sliding control for instantly switching from concentration to diafiltration, or switching gas and liquid lines simultaneously. Simplifies operation and avoids the need for multiple T-fittings and valves.

The selector valve provides a quick and simple way to switch the Amicon Stirred Cell between concentration and diafiltration modes without interrupting system operation. Four tubing connectors lead to the gas supply, the stirred cell, and the inlet and outlet ports of a reservoir (e.g. Amicon Stirred Cell Reservoir, cat no 6028).
