Introduction

As part of the research and characterisation for new molecules of vegetal origin, the Molecular Chemistry department of the University Joseph Fourier can provide you with access to its platform in order to extract your natural compounds for samples up to 2Kg.

The team can enable you to benefit from all its know how and its expertise in chimio-taxonomy to study the chemical link between vegetal species belonging to the same botanic family, as well as through pharmacognosis in order to improve natural substances (raw extracts or pure compounds).

100 - 500g samples

• Extractor mounted on a 6L flask with mechanical agitation and heating (finely controlled temperature)
  
  • Extractions with different organic or aqueous solvants

• Soxhlet version: extraction via heating cycle, condensation repeats indefinitely until complete exhaustion of the solid
  
  • Very efficient (compared to soaking)

Samples up to 2kg

• Large extractor with a 20L flask with mechanical agitation and controlled heating
• Soxhlet version (continuous)
• Version adapted to essential oil extraction by water vapour

• Mixer and continuous liquid/liquid extractor on a pilot scale for the purification of raw extracts obtained by sold/liquid extraction
  
  • Extraction by solvent density difference
  • Up to 150 litres (following solvants'  density)

• Rotating evaporators (1L, 3L, 10L) allowing the concentration and evaporation of organic or aqueous solvent extracts

• Freeze drying from 1 and  5L of trapped water

Applications

• Pharmaceuticals
• Cosmetics
• Agribusiness
