Integration

Fully Automated Liquid-Liquid-Extraction Automation for Chemical Purification

Our systems can incorporate a variety of racks and cartridges to match your demand. The following components are included in this example of a liquid-liquid-extraction system:

  1. Eightfold pipetting head next to an eightfold stirring head attached to a Z-axis. Fixed in Y-direction to match rack format and shorten the processing period.
  2. Wash station for pipetting and stirring probes. Ensuring clean pipetting and stirring probes during the whole process.
  3. Source rack. The crude product is placed here.
  4. Extraction rack. The extracted phase is transferred into the extraction rack if a second extraction step is necessary.
  5. Cartridge rack. The target product solution can be filtered with the cartridge rack.
  6. Filtrate rack. The filtrated target solution with the purified product ends up in the filtrate rack. Further analysis can be executed afterward.
  7. Pneumatic pressure spots. The pneumatic pressure spots are picked up here to apply pressure to the cartridges.
  8. Aqueous solution reservoir. The aqueous solvent is stored here.
  9. Eightfold precision syringe pump. High precision syringe pumps provide organic and cleaning solvents to be applied by the pipetting probes.
