Model IV Extractor


  • Complete immersion ensures good product contact with the solvent
  • Complete bed turnover prevents solids compaction and packing
  • Gentle motion and bed turnover minimizes product breakage
  • Vapor-tight design for operation with volatile solvents
  • Continuous operation requires minimal operator attention
  • Washes away products of reaction and excess reactants
  • The Model IV has been used for replacing solvent by washing with another solvent


  • Continuous counter-current extraction arrangement for improved extraction efficiency
  • Immersion in a bath of solvent for good solvent product contact without short-circuiting
  • Sanitary, easy-to-clean designs provide access for maintenance
