There is provided a breath condenser and a collection receptacle for receiving exhaled breath and collecting exhaled breath condensate. The collection receptacle comprises an outer cylinder having a sealed end and an inner cylinder having an inlet at a first end for receiving exhaled breath and an outlet at a second end. The inner cylinder is housed at least partially within the outer cylinder, the outlet of the inner cylinder being located toward the sealed end of the outer cylinder. In use, exhaled breath passes through the inlet, along the inner cylinder, through the outlet and along the outer cylinder, and condensate forms at least on the inside of the outer cylinder. The inner and outer cylinders are adapted to be used concomitantly in a centrifuge to accumulate the condensate in the bottom of the outer cylinder. The inner cylinder may be removable from the outer cylinder. The breath condenser comprises a cooling block for at least partially receiving the collection receptacle. When the collection receptacle is at least partially received within the cooling block, an outer surface of an outer wall of the receptacle is in contact with the cooling block and an inner surface of the outer wall is in contact with the exhaled breath. |
