A coupling member for pivotally coupling an end of a device to a mounting ball includes a body connectable to an end of the device and defines a socket for receiving a mounting ball. Levers of plug out of three plug, the plug being connected to hoods on both end sides of a receptacle, each have a length such as to project to outward from the hoods, and the levers are configured so as to be locked to a receptacle on the outside of the hoods. The microfluidic circuit is made of three or more substrate layers and preferably includes etched channels in different layers that are dimensioned relative to one another to provide for retaining the solid composition within the capillary separation conduits. The alignment device can also include an adapter that allows the alignment device to be mounted to a firearm by coupling to a corresponding slot of a mounting platform.
