Through the integration of preanalytics in a fully automated lab process, efficiency, security and quality of the entire analysis process will be considerably increased. The intelligent function of automated pre-selection of sample flow (Presorting) according to user-defined rules integrates the allocation of the samples to differing work places. Maximum variability due to optimal control while sorting is guaranteed. Varying sample holders such as centrifuge buckets, analyzer racks and other standard racks can be used. In the following you will find systems, enabling a timesaving and economical sorting of all samples – even after being given sorting priorities.
