1. A bodily-fluid transfer device, comprising:
a housing having an inlet port configured to be fluidically coupled to a bodily-fluid source and an outlet port configured to be fluidically coupled to a sample reservoir;
a fluid reservoir disposed in the housing and at least partially defined by the housing, the fluid reservoir configured to receive and sequester a first amount of bodily-fluid withdrawn from the bodily-fluid source; and
a flow controller disposed in an inner volume of the housing and forming a friction fit with an inner surface defining at least a portion of the inner volume, the flow controller configured to transition from (i) a first configuration in which the inlet port is in fluid communication with the fluid reservoir to facilitate a flow of the first amount of the bodily-fluid from the inlet port, through a first fluid flow path, to the fluid reservoir, to (ii) a second configuration in which the inlet port is in fluid communication with the outlet port to facilitate a flow of a second amount of the bodily-fluid from the inlet port, through a second fluid flow path, to the outlet port;
the flow controller configured to automatically transition from the first configuration to the second configuration after the first amount of the bodily-fluid flows into to the fluid reservoir.
