1. 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.
