A diagnostic analyzer system includes a linear track, at least one pipetting device, and at least one diagnostic module. The linear track includes a pre-treatment lane disposed parallel to at least one processing lane. The linear track moves reaction vessels, containing samples, held by the pre-treatment lane and by the at least one processing lane. The pre-treatment lane pre-treats the samples in the reaction vessels of the pre-treatment lane. The pre-treatment lane is not connected to any diagnostic module for testing the samples in the reaction vessels of the pre-treatment lane. The at least one pipetting device transfers the pre-treated samples from the reaction vessels in the pre-treatment lane to the reaction vessels in the at least one processing lane. The at least one diagnostic module is connected to the at least one processing lane for testing the pre-treated samples transferred into the reaction vessels in the at least one processing lane.

The drive device includes a guide element defining a guide track, the guide element being configured to receive and guide a cuvettes strip in translation along the guide track, and a drive belt configured to displace the cuvettes strip in translation along the guide track when the cuvettes strip is received in the guide element. The drive belt is disposed below the guide track and is configured to cooperate with lower portions of the cuvettes of the cuvettes strip when the cuvettes strip is received in the guide element.

A diagnostic analyzer includes a rotating device, a first optical reader, and a second optical reader. The rotating device includes a first darkened compartment, a second darkened compartment, and an optical path along which the first darkened compartment and the second darkened compartment travel. The first optical reader is operable to read the first darkened compartment and the second optical reader is operable to read the second darkened compartment.
