Cedex Bio analyzer 2 Introduction to the analyzer
Daily operation
Volume detection For each reagent set, the number of available tests is continuously calculated.
Periodic mixing Reagents may have a mixing interval defined. This interval is checked by the system
every 30 minutes, and mixing is performed without removing the reagent bottles
from the reagent disk.
For a reagent set that contains more than one reagent for which mixing is defined, the
shortest interval of all reagents of the set is used for all reagents.
Tests are blocked if any reagent they use requires mixing.
Diluents Both system water and dedicated diluents are used. System water is kept in the
external water container, dedicated diluents are supplied in reagent bottles and
placed on the reagent disk.
Cleaners Both a system cleaner and dedicated cleaners can be used. The system cleaner is kept
in the external cleaner bottle, dedicated cleaners are supplied in reagent bottles and
placed on the reagent disk.
