Abstract
A device and methods for sample distribution through a channel in which an expandable valve provides a mechanism to regulate flow through the channel. The valve may be configured to exert a force on a membrane layer so as to substantially block a portion of the channel to retain the sample in a desired location and prevent flow past the valve mechanism between the channel and a chamber.
