Abstract: An air chuck includes a body and a valve core interface. The body includes output, interface, and input ports. The body defines a first passageway that extends between the output and interface ports. The input port defines a second passageway that is in fluid communication with the first passageway. The valve core interface is slidably coupled with the body and is slidable between extended and retracted positions. The valve core interface includes a shaft and a knob. The shaft includes proximal and distal ends. The distal end is at least partially disposed in the first passageway. The knob is coupled with the proximal end of the shaft. The shaft is rotatably coupled with the body and is selectively rotatable in either tightening or loosening directions via the knob. The distal end of the shaft comprises a grasping feature that is configured to grasp a valve core of a valve stem.

Abstract: The present invention includes a spray drying disposable device for use in a spray drying system. The disposable has a spray drying head and a plasma drying chamber. The head has a spray dry nozzle assembly in fluid communication with the plasma source and the pressurized aerosol gas source. The pressurized gas flows in a vortex pattern that atomizes plasma droplets in the chamber. The head also includes a plenum has uniform air pressure of the drying gas. A baffle plate forms the floor of the plenum having drying gas jets that supply drying gas to the chamber. The atomized plasma droplets evaporate in the presence of the drying gas emitted from the jets to obtain dried plasma particles and humid air. A capture filter captures the dried plasma particles and allows the humid air to pass. The humid air passes through the gas outlet and the exhaust port.
