A microfluidic valve assembly includes a structure defining a microfluidic fluid path and an actuator that can be moved between different positions controlling flow through the channel. In one embodiment, the actuator can be threaded into at least a portion of the structure, and can be moved rotationally between a first position, causing relatively greater constriction of a microfluidic fluid path, and a second position causing relatively lesser constriction of the fluid path. Actuating the actuator, e.g., by rotation, can deform material between the valve and the fluid path, thereby constricting at least a portion of the underlying fluid path and regulating the flow of a fluid in the fluid path. In another aspect, the invention provides a reservoir into which fluid can be placed and from which fluid can be introduced into a microfluidic system. In one embodiment, the reservoir is expandable and thereby able to store fluid under pressure for delivery to a microfluidic system.
