Abstract
Rotary valves and methods of using, manufacturing, and storing the same are provided herein. The rotary valve includes a rotor and a stator, biased toward one another to form a fluid tight seal. In some implementations, the rotor comprises an integrated flow channel containing a porous solid support. Frequently, the interface between rotor and stator is made fluid-tight using a gasket. Some implementations of the rotary valve include a displaceable spacer to prevent the gasket from sealing against at least one of the rotor and stator prior to operation, wherein when the spacer is displaced, the gasket seals the rotor and stator together in a fluid-tight manner.
