A sample collection device for a fluid sample includes: a body including a capillary channel having a first end and a second end, wherein the first end is adapted to draw the fluid into the channel by capillary action an air vent located in the vicinity of the second end and in fluid communication with the capillary channel a barrier positioned within the capillary channel to prevent flow of the fluid by capillary action thereacross and features on opposing sides of the body to form an axis of rotation, which is substantially perpendicular to the overall direction of the capillary channel from the first end to the second end. In a preferred embodiment, the sample collection device is adapted to rotate about the axis of rotation within a cartridge having a sample manipulation device to bring the first end into position with the sample manipulation device.
