ANALYZER HAVING A ROTATABLE SAMPLE RACK CARRIER

摘要

An automatic chemical analytical apparatus for analyzing liquid samples. In order to provide a fully automatic transport of sample tubes containing samples to be analyzed the apparatus comprises a sample processing unit (61), sample transport means for transporting the sample racks (16) from a rack supply unit (18) to a rotatable sample rack carrier (19) in the sample processing unit and vice versa, and means for controlling and coordinating the operation of the sample transport means and the automatic pipetting unit (11). Sample processing unit (61) comprises an automatic pipetting unit (11) and a rotatable sample rack carrier (19) adapted to accommodate a plurality of sample racks (16), each sample rack (16) being adapted to accommodate a plurality of sample tubes (12).
