cobas s 201 system

The first multi-dye nucleic acid testing (NAT) screening system

The cobas s 201 system is a complete NAT solution able to meet both current and future needs of blood screening labs.

This system provides the efficiency and reliability of real-time polymerase chain reaction (RT-PCR) technology, modular automation, convenient ready to-use reagents and a robust menu selection. New assays utilize multichannel capabilities to provide real-time discrimination of major viruses.
The system is backed by world-class service and strong local support in over 140 countries.

Created from a unified vision...

An understanding of the need for improved productivity, scalability and reliability - the cobas s 201 donor screening system relies on real-time PCR technology supported by technician-friendly automated pooling, sample preparation, system monitoring and final results reporting. Its scalable design allows for expansion as needed with ready-to-use-reagents, integrated back-up capabilities and built-in contamination control. The cobas s 201 system is your customizable solution for flexible, automated, world-class NAT donor screening.

Automated Pooling

The automated Hamilton STAR family of pipettors and Roche’s proprietary Pooling Wizard software is unsurpassed for ease in pooling.

Pooling and Data Management Server

The single high-capacity server can accommodate multiple configurations to meet variable throughput needs while providing system safeguards such as data back-up, data recovery, data redundancy and data retrieval capabilities.

Scalable and Flexible Automation

Powered by a single high-capacity server, the cobas s 201 system lets you establish and change system configurations to meet your workflow requirements with less labor and provides integrated back-up capabilities.

Scale up or scale down. You can implement a world-class system today that can change to meet your needs tomorrow.

Technology to Support Emerging Pathogens

The cobas s 201 system supports assays with a platform designed for detection of emerging pathogens. The system is designed to easily accommodate future needs.

Start-to-Finish Monitoring

The system monitors samples, ready-to-use reagents, disposables and the testing process from start to finish.

User-Friendly Software and Server

The software and server provide system security, surveillance and reporting capabilities. Roche is raising the bar in laboratory quality by providing maximized flexibility with full system audit and data security.
