A cable reel or cable reel assembly is provided for storing, deploying, retrieving and transporting a cable assembly. The band pass filter is formed in the laminated substrate. Sharing a web browser application management framework provides the capability for rapidly switching between applications, allows for multitasking, facilitates using a common set of input controls for applications, and makes it possible for applications to be available with little perceived startup time. Preferred devices may be fabricated with substantially planar device layers, including stencil layers, that are directly bonded without adhesives to form a substantially sealed microstructure suitable for performing pressure-based chromatographic separations at elevated operating pressures and with organic solvents.
