1. An apparatus for concentrating constituents from a fluid, comprising:
a connector body in fluid communication with a fluid channel;
a first reservoir having a variable pressure;
a second reservoir having a variable pressure, wherein the first reservoir is fluidly coupled to the second reservoir through the connector body while maintained at an angle relative to the second reservoir, wherein the connector body is sized to flow a desiccant between the first reservoir and the second reservoir;
a biasing element positioned inline with the second reservoir and configured to provide a pressure against a plunger within the second reservoir;
a withdrawal channel in fluid communication with the fluid channel; and
a filter positioned within the connector body to prevent passage of the desiccant from the fluid channel into the withdrawal channel.
