  "id": "MLC-T-CHM-003167",
  "term": "Differential contactor",
  "field": "Chemistry",
  "definition": "An apparatus designed for continuous countercurrent extraction processes, where two immiscible liquid phases flow past each other, allowing for mass transfer of a solute between them. The concentration of the solute changes continuously along the length of the contactor, creating a concentration gradient that drives the separation. Examples include packed columns and spray columns.",
