Fast, Easy, and Reliably Accurate

PCR analysis is traditionally a multi-step process where a skilled lab technician tests many samples simultaneously. The cobas® Liat® PCR System fully automates these steps, allowing for the rapid, accurate analysis of single samples.

Offering a turn-around time of 20 minutes or less, this fast, flexible solution requires minimal training, making it ideal for situations when there is a pressing need for a rapid diagnosis and treatment decision. The cobas® Liat® PCR System is on-site molecular testing you can depend on, whether it’s in STAT or out-of-hours situations or for use in point of care or satellite locations.

Lab-quality results made accessible with the cobas® Liat® PCR System



Perfectly sized for settings where space is limited



Definitive results in 20 minutes or less



Fully automated system with minimal hands-on time



Powerful PCR technology expertly designed with a built-in internal control

Secure your confidence

The cobas® Liat® PCR System has extensive internal control measures that ensure you get the high-quality results you expect from PCR analysis.

The cobas® Liat® assay tube contains a set of chemical reagents that copy and amplify DNA or RNA sequences which are unique to a particular infectious disease.

The cobas® Liat® Analyzer


The small benchtop analyzer is safeguarded by an extensive array of instrument control measures, and automates all nucleic acid testing processes

  • Reagent preparation
  • Target enrichment
  • Inhibitor removal
  • Nucleic acid extraction
  • Amplification
  • Real-time detection

The cobas® Liat® assay tube


The cobas® Liat® Analyzer compresses the assay tube to selectively release reagents from tube segments, move the sample from one segment to another, and control reaction conditions at different temperatures.
