JANUS G3 BioTX Pro Plus Workstation

The JANUS® G3 BioTx Pro Plus Workstation enables consistent, time-saving small-scale protein purification and sample preparation for analytical protein characterization required to support quality by design experimentation in both upstream and downstream processes. It offers full walkaway automation for high-throughput process development, enabling more data from precious starting materials and limited resources.

Offline capabilities only, you must also order CLS153940 for full cloud access. For research use only. Not for use in diagnostic procedures.


The JANUS® G3 Bio Tx Pro Plus Includes:

  • Independent 8-channel pipetting arm combined with gripper equipped 96 channel multiple dispensing head for high throughput liquid handling and plate movement
  • Fully integrated vacuum filtration system for plate based purification and fraction collection
  • Easy reconfigurable deck for PhyNexus PhyTips®, GE PreDictor plates and Media Scout® RoboColumns
  • Automated fraction collection for whole and partial plates utilizing Media Scout® RoboColumns

The JANUS BioTx Pro and Pro-Plus Workstations are developed as intuitive, flexible, automated instruments capable of performing parallel small-scale analytical protein purification. A graphical user interface was developed to accommodate 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. Three modes of small scale protein purification can be automated on a single platform:

  • PhyNexus PhyTips®
  • GE PreDictor plates
  • Media Scout® RoboColumns

Two workstations are available to address your throughput and budgetary needs.


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