JANUS® G3 NGS Express Workstation

The JANUS® G3 NGS Express™ workstation is a benchtop liquid handler designed to simplify and reduce errors in low-to-moderate throughput next generation sequencing library construction. It uses an intuitive interface to guide users through protocol selection and deck setup, as well as, displays in-run status and details. An optional enclosure not only helps to minimize sample contamination, but the easy to read status lights provide visual feedback for true walkaway sample preparation. Another advanced option is the PKeye™ mobile operations monitor, which empowers full walk-away automation through the use of integrated deck cameras.

PerkinElmer has automated a number of kits and protocols for the construction of NGS libraries on the JANUS G3 NGS Express liquid handler. New protocols are continuously being developed, updated and optimized to provide the best sample preparation experience.

NGS applications automated on the JANUS G3 NGS Express workstation include:

  • Library preparation
  • Amplicon preparation
  • Target capture preparation
  • Sample normalization

See if your library preparation protocol is already developed for the JANUS G3 NGS Express workstation.

The JANUS® G3 NGS Express™ workstation is compatible with a wide range of consumables. From disposable tips to microplates and reagent troughs, PerkinElmer provides high quality consumables to meet your liquid handling needs.
