Detail Information

The JANUS® G3 BioTx Pro workstations enable consistent small scale protein purification and sample prep for analytical protein characterization required to support quality by design experimentation in both upstream and downstream processes. The JANUS BioTx Pro workstations are intuitive, flexible, automated instruments capable of performing parallel small-scale analytical protein purification. A graphical user interface accommodates a variety of screening experiments designed to determine the optimal conditions for purification of biotherapeutic proteins using small-scale, commercially available ion exchange and affinity chromatography solutions. With just one instrument, you can achieve rapid analysis of a range of sample volumes and concentrations to support Quality by Design experimentation in both upstream and downstream processes:

  • Expression optimization
  • Cell line selection
  • Purification process development
  • Bioanalytical sample prep

The JANUS BioTx Pro workstations are compatible with the following modes of purification:

  • Nexus PhyTips® columns
  • Atoll® RoboColumn® products
  • MediaScout® MiniChrom columns
  • GraviTrap® Columns
  • Resin-filled microtiter vacuum filtration plates

Two models of the JANUS BioTx Pro workstations are available to meet varying requirements
