Disclosed is a device (10) for collecting a biological sample, the device comprising an elongate handle (40) extending generally along a handle axis, and a sample collecting head (20) removably supported or supportable on the handle, the head being formed from a porous folded planar or sheet material, optionally including a plurality of arms (22-28 FIG. 2) each extending away from the handle axis in a different direction. An ejection handle is provided. Disclosed also is an efficient method for extracting DNA information from the device.
