Zusammenfassung:	Methods for detecting the presence and/or volume and/or identity of liquid in a transparent carrier include directing a light source towards the carrier; recording an image of light refracted by the carrier with a camera; and deriving information regarding the presence and/or volume of the liquid in the carrier from the recorded image of the light refracted by the carrier. Devices for detecting the presence and/or volume and/or identity of liquid in a transparent carrier include a camera directed towards the carrier; a light source directed towards the carrier; and means for recording an image of light from the light source as refracted by the carrier and captured by the camera.
