ABSTRACT:
An analyzer, preferably a desktop analyzer, includes: a stationary probe capable of dispensing or aspirating a liquid; one or more of a movable test element or movable liquid source; and a conveyor for moving the movable test element or liquid source with respect to the stationary probe. In a preferred embodiment, the conveyor includes a dual rotor conveyor. A method of dispensing or aspirating a liquid into a test element includes: providing a movable test element having identifying marks, such as a barcode, thereon and a movable sample liquid supply; providing a stationary probe; reading the identifying marks to determine which test is to be performed and the dimensions of the test element; moving the movable sample liquid supply into registration with the probe; aspirating sample into the stationary probe; and moving the movable test element into registration with the probe, wherein the registration of the test element with the probe is controlled by the test to be performed. In a preferred embodiment, the method is implemented by a computer program interfacing with a computer.
