The Beckman Array 360 Analyzer is a diagnostic analyzer for in vitro quantitation of components in biological fluids by rate nephelometry and nephelometric inhibition through measurement of light scatter resulting from an immunoprecipitin reaction.

Individual tests, panels, or batch determinations are automatically performed for up to 40 samples with up to 20 analytes per sample.  Samples are automatically diluted and delivered to reaction flow cells along with other reactants.  The nephelometer derives the final result in concentration units.  All tests requested for each sample are completed, including out of range and antigen excess checks, before printing the next sample. 

This analyzer is composed of three modules: the analyzer, CRT display, keyboard and printer.  The analyzer contains the nephelometric optics, fluid transport system, a twenty position reagent wheel, and forty position sample wheel, card reader, and an electronics compartment.

Excellent calibration stability from manufacturer supplied reagents of 14 days for each protein chemistry and 7 days for each drug chemistry

The instrument can also perform analysis for user prepared reagents and such user prepared assays can be stored in the computer memory.
