A device for collecting and transferring liquid samples having a detachable sample collecting portion includes an elongated body with a liquid collecting portion disposed at one end and a handling portion disposed at the other end separated by a frangible portion. The sample collecting portion includes an inner surface configured to be wetted by the sample. After collection, the sample is transferred into a separate housing by inserting the sample collecting portion filled with sample into a confining cavity and subsequently breaking the sample transfer device along the frangible portion. The liquid sample is extracted from the collecting portion using known means to drive and control flow in fluidic devices including rotation, capillary pressure or pneumatics. The separate housing may be part of a device capable to process the liquid sample to provide for a system for handling liquid samples.
A sample transfer device comprising a sample collecting portion and a handling portion separated by a frangible portion, wherein the sample collecting portion comprises a cavity having a first opening at an inlet end of the sample transfer device to allow a sample liquid to be drawn into the cavity and a second opening to allow air to escape from the cavity as liquid is drawn into the cavity and wherein the frangible portion comprises a weak section of material with reduced resistance to breaking compared to adjacent sections of the sample transfer device adjacent to the weak section to facilitate separation of the sample collecting portion and the handling portion.
