cobas® Liat® System
The cobas® Liat® Analyzer compresses the assay tube to selectively release reagents from tube segments, moves the sample from one segment to another, and controls reaction conditions at different temperatures. Each cobas® Liat® assay tube contains all assay reagents for a single test, prepared in isolated segments – add nothing but your patient sample. All nucleic acid testing processes are fully automated, including sample preparation, amplification and real-time detection.
